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 → 250 A (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.
