BREAKERS
The following statement is a full description of this invention, including the best method of performing it known to us 1 RESIDUAL CURRENT CIRCUIT BREAKER ASSOCIATED TO ONE OR MORE CIRCUIT PROTECTION ELEMENTS SUCH AS FUSE CUT-OUTS OR CIRCUIT BREAKERS.
The present invention is related to a residual current circuit-breaker connected in series to one or more protective elements, such as fuse cut-outs or circuit breakers. The circuit breaker and the above-mentioned protective elements preferably being housed in cases including two opposite narrow side faces having input and/or output connection terminals, and two opposite side walls via which said cases are adjoined two by two, thereby enabling the 10 downstream connection terminals of the residual circuit breaker to be electrically connected to the upstream connection terminals of the protective elements.
Power supply for of the switch circuit breaker and protective elements of Sthe kind previously mentioned is achieved in state-of-the-art manner, in the prior art is supplied via the top or via the bottom of the device depending on the country of use, by means of cables. And, when all these elements are fitted on the same rail, connection of the output terminals of the switch circuit breaker to the input terminals of the protective elements requires a tricky passage of the cables from the bottom to the top (or in the reverse direction from top to bottom, in case of power supply via the bottom), resulting in the assembly occupying a large space and not being easy to fit.
The present invention overcomes these problems and proposes a residual current circuit-breaker which may be associated with to one or more protective elements of small dimensions and which make the fitter's job easier.
For this purpose, the object of the present invention is to achieve a residual current circuit-breaker designed to be connected in series to one or more protective elements, such as fuse cut-outs or circuit breakers, the circuit breaker switch and the above-mentioned protective elements ideally being housed in cases including two opposite narrow faces having input and/or output connection terminals, and two opposite side walls via which said cases are joined, thereby enabling adjoined two by two, the output terminals of the circuit breaker switch being to be electrically connected to the input terminals of the one or more protective elements, wherein the output terminals of the circuit 2 breaker switch and the input terminals of the protective elements are located on the same side of the cases. Conveniently, the above-mentioned output terminals are being separated two by two by a preset distance corresponding to the distance separating the input terminals of the one or more protective elements, so as to enable said terminals to be connected to a connecting comb located on the same side as the power supply of the one or more protective elements, the circuit breaker switch includes the same number of output terminals on its two opposite faces, so as to enable the comb to be connected on either side of the cases and the case of the circuit breaker switch may also 10 include in addition the same number of input terminals on its two opposite narrow faces.
According to a particular embodiment of the invention, the output terminals of the circuit breaker switch and the input terminals of the protective elements are located on the same side as the power supply of the circuit 15 breaker switch.
According to another feature, the above-mentioned protective elements may include at least one fuse cut-out and/or at least one circuit breaker.
According to another feature, the circuit breaker switch and the protective elements may be are of the single-pole and neutral type.
But other further advantages and features of the present invention will become more clearly apparent from the following detailed description which refers description referring to the accompanying drawings and is given as an example only and in which: Figure 1 illustrates in a schematic view a single-pole and neutral residual current circuit-breaker associated to two single-pole and neutral circuit breakers, according to a particular embodiment of the invention.
Figures 2, 3 and 4 illustrate respectively, also in schematic views, three other embodiments of the residual current circuit-breaker according to the invention.
In figure 1, a single-pole and neutral switch I can been of the king kind generally used for protection of several electrical circuits, associated can be seen connected to two single-pole and neutral circuit breakers D, E. This switch I and its associated circuit breakers D, E are each housed in a respective cases 1, 2, 3 of parallelepipedic shape, each comprising two opposite narrow faces la, Ib; 2a, 2b; 3a, 3b; on which connection terminals are located, and two opposite side faces Ic, Id; 2c, 2d; 3c, 3d via which the different elements are coupled. Thus, the two circuit breakers D, E comprise two phase and neutral input connection terminals 4, 5 and 6, 7 located on their upper narrow face 2a, 3a and two phase and neutral output connection terminals 8, 9 and 10, 11 located on their lower narrow face 2b, 3b. According to an embodiment of the invention, the upper face la of the case 1 of the switch I comprises two input terminals 12, 13 respectively phase and neutral and two input output terminals 14, 15 also phase and neutral, and these two output terminals 14, 15 are separated by a distance corresponding to the distance separating the input terminals 4, 5 and 6, 7 of the circuit breakers D, E, E, D,which tFerminals are located on the upper narrow faces 2a, 3a of the cases 2, 3. When mounting takes place, the assembly is placed on a DIN rail (not represented). The 20 electrical connection between the output terminals 14, 15 of the switch I and the Sinput terminals 4, 5 and 6, 7 of the circuit breakers E, D D, E is achieved by means of a standard single-pole plus neutral connecting comb P connected to the output terminals 14, 15 of the switch I and the input terminals 4 to 7 of the circuit breakers E, D D, E. The output terminals 8 to 11 of the circuit breakers E, 25 D D, E are connected to the corresponding terminals of the electrical switchgear located downstream (not represented), and the input terminals 12, 13 of the switch I are connected to power supply cables C.
In figure 2, we can see a residual current circuit-breaker whose two input terminals 12, 13 and output terminals 14, 15 are arranged on the lower narrow face lb of the case 1, enabling connection of the comb P and power supply of S" said switch I via the bottom.
In figure 3, according to another embodiment of the invention, the residual current circuit-breaker I comprises four connection terminals 12 to on its upper narrow face la and four connection terminals 12a to 15a on its lower narrow face lb, so as to enable power supply of said switch I and of the circuit breakers E, D via the top or the bottom as required. This embodiment of a switch with double terminals enables swift connection in a modular enclosure.
In figure 4, according to yet another embodiment of the invention, the residual current circuit-breaker I comprises two input terminals 12, 13 and two output terminals 14, 15 on the upper narrow face la of the case 1, and two output terminals 14a, 15a on the lower narrow face lb of said case 1. In this way, if power supply of the switch I has to be performed via the top, connection of the comb P and therefore power supply of the circuit breakers E, D D, E can be achieved either via the top or via the bottom as desired.
It will be noted that other protective elements that besides circuit breakers could have been used in association with a residual current circuit-breaker, such as fuse cut-outs or others for example.
A residual current circuit-breaker associated to circuit protection elements has thus been achieved by means of the invention enabling existing standard combs to be used without the help of other difficult to wire connections, which reduces the dimensions of the assembly and makes the fitter's job easier.
S 20 Naturally, the invention is not limited to the embodiments described and Sillustrated herein which have been given as examples only.
On the contrary, the invention comprises all the technical equivalents of the means described as well as their combinations if the latter are achieved according to the spirit of the invention.
