NZMN3-A500 Circuit breaker 109671

Power switch – reliable protection for electrical installations

This three-pole power switch NZMN3-A500 from Eaton is a solid solution for protecting electrical circuits with a rated current of up to 500A. Designed for both industrial and public building applications, it provides effective protection against overloads and short circuits. Its fixed mounting design guarantees stability and long-lasting reliability.

This switch is characterized by a high short-circuit breaking capacity – up to 50 kA at 400V, making it an ideal choice for installations exposed to high surge currents. Thanks to the overload release setting range from 400 to 500A, it can be precisely adjusted to the load characteristics. Made with attention to detail, with screw connections, it ensures secure and durable wire connections.

Characteristics and application

The NZMN3-A500 switch is a device designed to protect against the effects of overloads and short circuits in electrical circuits. Its lever-based design allows for quick and intuitive operation. The location of the main circuit connections on the front side facilitates installation and connection of wires. The IP20 degree of protection provides basic protection against touch and ingress of solid objects.

It will find application in:

• Electrical distribution boards
• Protection of machines and industrial equipment
• Electrical installations in public buildings
• Energy distribution systems
