Isolation Characteristics

Circuit breakers offer positive contact indication and are suitable for isolation in accordance with standards IEC/EN60947-1 and IEC/EN60947-2. The O (OFF) position of the actuator is sufficient to isolate the circuit breaker.

The following markings on the device identification label indicate that the devices are capable of isolation:

Circuit Breaker

Automatic Switch

In accordance with installation rules, circuit breakers can be locked in the O (OFF) position so that work can be carried out with the power off. Circuit breakers can be locked in the O (OFF) position only when they are open.

NOTE: Locking a circuit breaker in the O (OFF) position is sufficient to isolate the circuit breaker.

The choice of locking device depends on the type of actuator:
