Merlin Gerin multi 9 3 Phase MCB and RCD Module Teardown

A defective Merlin Gerin MCB/RCD combination is totally dismantled to see what is inside.

These are 3 phase devices, and the RCD is an add on module which can only be used with the matching circuit breaker, the RCD doesn't have any switching mechanism in it.
