FAQ

Question?

Is this a circuit breaker or a switch disconnector?

This is a switch disconnector (model iSW-NA), designed for safely isolating circuits. It does not provide overcurrent protection like a miniature circuit breaker (MCB).

What does the '1P+N' designation mean for this A9N19636 model?

'1P+N' means it has one protected/switched pole (for the phase) and one solid neutral pole that is not switched but provides a connection point. This is common in single-phase applications where the neutral line should remain connected.

Can this switch be used with auxiliary contacts from the Acti9 range?

Yes, the Acti9 iSW-NA series is compatible with the standard Acti9 range of auxiliaries, such as indication contacts (iOF) or shunt trips (iMX), allowing for enhanced control and monitoring functionalities.
