Overcurrent circuit breaker 25kA, In=80A, B characteristic. 3+N pole. AZ-3N-B80 174525

3+N Pole Overcurrent Circuit Breaker – Reliable Installation Protection

This three-pole overcurrent circuit breaker with an additional neutral pole (3+N) is a key element of electrical protection in residential and commercial buildings. It provides effective protection against overload and short circuit, protecting both the installation and connected devices. Its short-circuit strength of up to 25kA guarantees safety even in difficult conditions.

Characteristics and application

A circuit breaker with B characteristic is particularly recommended for protecting circuits with receivers with high inrush current, such as motors, transformers or heating devices. The B characteristic allows it to react more slowly to short current surges, so it tolerates starting devices with a motor well. The rated current of 80A makes it ideal for protecting circuits with higher power demand. The 3+N construction provides complete protection in three-phase installations with a neutral wire.
