SCHNEIDER ELECTRIC iC60N D4A A9F05204

Schneider Electric iC60N 2-Pole Miniature Circuit Breaker

Description

This is the iC60N miniature circuit breaker (MCB) from Schneider Electric, part number A9F05204. It is a 2-pole device with a 4 Ampere rating and a D-type tripping characteristic. Designed for DIN rail mounting, it provides reliable protection against both short-circuits and overloads in industrial and commercial electrical installations. The D-curve makes it especially suitable for circuits with high inrush currents, such as those with motors or transformers.

FAQ

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

A D-curve breaker, like this iC60N D4A, is designed for circuits with very high inrush currents, typically 10 to 20 times the rated current. This makes it ideal for protecting motors, transformers, or large capacitor banks. A C-curve breaker has a lower trip threshold (5 to 10 times the rated current) and is used for more general applications like lighting and standard outlets.

Can this 2-pole breaker be used on a single-phase system?

Yes, this 2-pole (2P) breaker can be used in a single-phase system to disconnect both the live (phase) and neutral conductors simultaneously. This provides a complete isolation of the circuit, which is often required or recommended for safety in specific applications or according to local regulations.

What does the ‘6000’ on the front of the breaker signify?

The ‘6000’ in the box on the front indicates the rated short-circuit breaking capacity (Icn) in Amperes, according to the IEC/EN 60898-1 standard for household and similar installations. It means this breaker can safely interrupt a short-circuit fault current of up to 6000 Amps at its rated voltage without being damaged.
