SCHNEIDER

1.Main Functions

1. It is an accessory matched with Acti9 miniature circuit breakers and disconnectors to collect the mechanical position status of the main contacts of the circuit breaker.
2. It provides one Normally Open + one Normally Closed (1NO + 1NC) potential-free changeover contact.
3. It does not switch the main power circuit, and is only used for status feedback.
4. The contact state changes when the circuit breaker is closed; the contact resets when the circuit breaker opens or trips (overload / short-circuit).

Note: iOF reflects only the mechanical position of the switch. It is different from iSD fault signalling contact. iSD only activates under short-circuit or overload trip conditions.

2. Applications

1. In electrical control cabinets: transmit circuit breaker ON/OFF status signals to PLC, monitoring systems or indicator lights.
2. Realize remote status monitoring and electrical interlock logic.
3. Status signal collection for building power distribution, industrial low-voltage power distribution and data center power supply circuits.
4. Supporting component for complete switchgear and distribution boxes.
