Hello

T7 M (CB1) and T7 M (CB2) Interlocked
XT4 (CB3) for disconnection
Non-priority loads (NPL)
To achieve a correct configuration, each circuit-breaker connected to the ATS must be accessorized with:
• mechanical interlock;
• motor operator for opening and closing;
• key lock against sole manual operation for MOE motor operators;
state (open/closed) and tripped contact signalling contact;
• connected contact (for the withdrawable circuit-breaker version).

Could you enlighten me on what "
state (open/closed) and tripped contact signalling contact
" means?

Thank you.

I'd guess that state (open/closed) and tripped contact signalling contact describes a terminal to which you can attach a wire. The wire can be energized from a source other than the one the breaker protects. You can use the current on the wire to signal the status of the breaker.

It would be a pair of wires. The contact inside the breaker would open or close depending on the status.
