3-pole circuit breaker 50A BG1 NZMN1-A50 259082

Power circuit breaker – reliable protection for electrical installations

This three-pole power circuit breaker with a rated current of 50A is a key element of every safe and efficient electrical installation. Designed by the renowned company Eaton, model NZMN1-A50 provides effective protection against overloads and short circuits, guaranteeing uninterrupted power supply and minimizing the risk of failure. It is a device designed for fixed mounting, but with the option of mounting on a DIN TH rail, which provides flexibility in choosing the installation method.

Characteristics and application

The NZMN1-A50 circuit breaker uses a thermomagnetic release, which means it reacts to both the temperature increase caused by an overload and the sudden increase in current in the event of a short circuit. The setting range of the overload release allows precise adjustment to the specifics of the protected installation (40-50A), and the short-circuit release range (300-500A) ensures a quick response in emergency situations. The rated short-circuit breaking capacity at 400V is as high as 50kA, making it an ideal solution for demanding industrial and commercial applications.

It will find application in protecting electrical circuits in residential, commercial and industrial buildings. It will be perfect in installations powering motors, lighting, sockets and other electrical devices. Thanks to the possibility of mounting on a DIN TH rail or permanently, it is easy to integrate with existing switchboards.
