Power switch 3-pole 400A BG3 NZMN3-AE400 259114

Power circuit breaker for installation and device protection. 3-pole circuit breaker with a rated current of 400A, from the NZMN3-AE400 series by Eaton Electric, is a reliable solution for protecting electrical circuits against overload and short circuit. Designed for a wide range of applications, both in building and industrial installations. Its solid construction and high short-circuit breaking capacity (50kA at 400V) guarantee safety and continuity of power supply.

Characteristics and application

This circuit breaker is designed for fixed mounting and features screw connections for the main contacts. Thanks to the adjustable overload release range (200-400A) and short-circuit release range (800-4400A), it can be precisely adapted to the specific requirements of the protected installation. It is ideal for securing electrical switchboards, machines and devices with high power consumption. The IP20 degree of protection provides protection against touch and dust.
