Overcurrent circuit breaker 25kA, In=25A, characteristic D. 3+N pole. AZ-3N-D25 174529

25kA Overcurrent Circuit Breaker – Reliable Protection for Electrical Installations

This three-pole circuit breaker with an additional neutral pole (3+N) is a key element ensuring safety in any electrical installation. Designed by Eaton, model AZ-3N-D25 features a high short-circuit breaking capacity – up to 25kA – guaranteeing effective protection against the effects of sudden overvoltages and short circuits. Designed to operate in AC networks with a rated voltage of 400V, it is perfect for both home and industrial installations.

Characteristics and Application

The circuit breaker with characteristic D is particularly recommended for protecting circuits with receivers with high inrush current, such as electric motors, pumps, and compressors. Characteristic D allows for short-term overloads without unnecessary tripping, which increases user comfort and minimizes the risk of downtime. The rated current of 25A provides adequate protection for a wide range of devices and installations. Additionally, the presence of a neutral pole enables full circuit protection, including against phase-to-neutral short circuits.
