Circuit breaker 4-pole 160A NZMN2-4-A160 265860

4-pole power switch 160A is a component of the NZM..-A series by Eaton, designed for reliable protection of electrical installations, generators and motors. The device is characterized by a compact design and flexibility of mounting, thanks to the possibility of using modular function groups. It is a versatile solution, proving useful in various applications on the IEC market.

Characteristics and application

This switch is equipped with a thermal-magnetic release, which provides protection against the effects of overloads and short circuits in electrical circuits. The setting value of the release in the neutral conductor is automatically synchronized with the setting value of the external current, which simplifies configuration and ensures consistent protection. The rated continuous current of 160A allows for the protection of circuits with significant power consumption. The possibility of optional mounting on a DIN TH rail further increases the flexibility of the installation.

Construction and parameters

The construction of the switch is based on a solid, durable fixed-mounted device. It has a lever as an actuator, allowing for manual switching on and off of the circuit. The rated short-circuit switching capacity at 400V, 50Hz is as high as 50kA, which guarantees effective protection in the event of a serious failure. The switch is adapted to work in circuits with a rated voltage of 690V. The degree of protection IP20 provides basic protection against touch and ingress of solid objects. Power losses are 38.4W. The location of the main circuit connections on the front side facilitates the connection of wires.

• Short-circuit switching capacity: high value of 50kA ensures the safety of the installation even with large short-circuit currents.

• Mounting flexibility: possibility of mounting both fixed and optionally on a DIN TH rail facilitates integration with various types of switchboards.

• Thermal-magnetic protection: effectively protects against overloads and short circuits, protecting devices and cables from damage.

• Wide voltage range: adapted to work in circuits with a voltage of up to 690V, making it a universal solution for many industrial and commercial applications.

• Solid construction: ensures long-lasting and reliable operation in demanding environmental conditions.
