Description Residual circuit-breaker, 2 and 4Pole This 2 / 4Pole RCD meets DIN VDE 0664 Part 1. It records AC and pulsating DC. Test symbols: VDE; ÖVE; SEV; CEBEC; SEMKO; NEMKO; DEMKO; FIMKO; KEMA. Un = 230VAC with 2Pole, Un = 230VAC / 400VAC with 4Pole. ### Kopp — residual circuit-breaker ### Highest Precision The measuring equipment fitted with a summation current transformer handles AC and pulsed DC fault currents and is not sensitive to surge currents → 250A (pulse design 8//20, DIN VDE 0432 part 2). In accordance with DIN VDE 0664 part 1, in the event of a failure the equipment switches off within 0.2 sec. **Convenient mounting** The patented quick fix feature of the KOPP MCB is also used in this protection circuit series. This makes it easy to lock them into the DIN rail and also remove them from the connection if required. **Clear detection of the switch-off source** As was the case with the MCB, even the switch-off source for residual circuit-breakers can be detected from the lever position. If the lever is in the "OFF" position, the switch-off was manual and intentional. If, on the other hand, it is in the "RESET" position the device was switched off by a residual current in the system. **Sophisticated wiring technology** On delivery, the terminals are already opened and you have the option to cross-wire the devices with the commoning bar - all helping you save on installation time and therefore cost.
