The SBM2 is an interlocking unit designed for ABB breakers.
Allowing you to safely remove the breaker, isolate it by means of a trapped key. This key is inserted into the SBM2 allowing you to unlock the earth (in the off position). Then the earth be applied (in the on position). This is then locked and the second key removed.
