SCHNEIDER ELECTRIC iC60N D40 A9F75340

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. Specifications Manufacturer: Schneider Electric Product Series: Acti9 iC60N Part Number: A9F75340 Poles: 3-Pole (3P) Rated Current: 40 Amperes Tripping Curve: D Rated Voltage (AC): 400 V Breaking Capacity: 6 kA (acc. to EN/IEC 60898-1) Auxiliary Contact: 1x OF (Open/Fault) Mounting: DIN Rail Label Info Model: iC60N Rating: D40 (D-Curve, 40A) Voltage: 400V Breaking Capacity: 6000 Application This MCB is suitable for a wide range of applications in industrial automation, building management, and machine control where protection of three-phase circuits with high inrush loads is required. Country of Origin Made in India. CO2 Impact Reusing this circuit breaker saves approximately 16 kg of CO2 compared to manufacturing a new one. This saving is equivalent to the emissions from driving a car for 80 kilometers. Availability This item is in stock and available for immediate dispatch.

FAQ What is the purpose of the D-curve on this iC60N circuit breaker?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. Can the included OF auxiliary contact be replaced or removed?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. What is the VisiTrip feature on Schneider Acti9 circuit breakers?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.
