SCHNEIDER ELECTRIC iC60N D3A A9F75203

Schneider Electric iC60N A9F75203 Circuit Breaker

Description

The Schneider Electric A9F75203 is a high-performance miniature circuit breaker (MCB) from the renowned Acti9 iC60N series. This 2-pole device provides robust protection for electrical circuits against both short-circuits and overload currents. With a D-type tripping curve, it is specifically designed for circuits with high inrush currents, such as those involving motors, transformers, and certain lighting systems. Its compliance with major international standards makes it suitable for a wide range of industrial and commercial applications.

FAQ

What is the difference between a D-curve and a C-curve circuit breaker?

A D-curve breaker, like this A9F75203, is designed to handle high inrush currents, typically 10 to 20 times the rated current. It’s ideal for protecting circuits with transformers, motors, or other highly inductive loads. A C-curve breaker has a lower trip threshold (5 to 10 times) and is used for general-purpose applications like lighting and sockets.

Is this iC60N breaker compatible with older Merlin Gerin Multi 9 systems?

Yes, the Schneider Electric Acti9 iC60N series is the successor to the Merlin Gerin Multi 9 range and is designed to be physically and electrically compatible. It can typically be used as a direct replacement in existing Multi 9 distribution boards.

What do the green and red indicators on the front signify?

The Acti9 series features VisiSafe and VisiTrip indicators. The green strip (VisiSafe) confirms that the contacts are physically open, ensuring downstream safety for maintenance. The red mechanical indicator on the toggle (VisiTrip) appears when the breaker has tripped due to a fault (overload or short-circuit), allowing for quick identification of the faulty circuit.
