Schneider Electric iC60N D40 3-Pole 40A Circuit Breaker

Description

The Schneider Electric iC60N D40 is a robust miniature circuit breaker (MCB) from the market-leading Acti9 range. It provides essential protection for electrical circuits against short circuits and overload currents. This 3-pole model is rated for 40A with a D-curve tripping characteristic, making it ideal for protecting circuits with high inrush currents, like those with motors or transformers. The attached OF auxiliary contact allows for remote monitoring of the breaker's status (open/closed/tripped). This component is designed for DIN rail mounting in industrial and commercial distribution boards.

FAQ

The D-curve is a thermal-magnetic tripping characteristic designed for circuits with very high inrush currents. It trips between 10 and 20 times the rated current, making it suitable for protecting motors, transformers, and power supplies without nuisance tripping on startup.

Yes, the OF auxiliary contact is a modular accessory for the Acti9 series. It can typically be unclipped from the side of the MCB and replaced with another type of auxiliary or removed if not needed.

VisiTrip is a safety feature on Acti9 breakers that provides a clear visual indication on the front face when the device has tripped due to a fault (overload or short-circuit). This allows for quick identification of the faulty circuit, reducing downtime.
