Cable-type door interlock IPA
This option prevents door opening when the circuit
breaker is closed and prevents circuit breaker closing
when the door is open.
For this, a special plate associated with a lock and a
cable is mounted on the right side of the circuit breaker.
With this interlock installed, the source changeover
function cannot be implemented.
