Circuit breaker 3-pole 160A NZMN1-A160 281234

Power switch – reliable installation protection

The NZMN1-A160 power switch is a key element of every electrical installation, providing effective protection against overloads and short circuits. Designed by Eaton, this 3-pole switch with a rated current of 160A and a short-circuit breaking capacity of 50kA at 400V guarantees safety and system stability. The device is particularly recommended for applications requiring high reliability and durability.

Design and functionality

The NZMN1-A160 switch is characterized by a solid construction of a fixed device, which ensures stable mounting. The frame terminal facilitates the connection of the main circuit, and the lack of an integrated short-circuit to ground protection and undervoltage releases makes it an ideal solution for specific industrial applications. The optional DIN rail mounting capability further increases installation flexibility.

Advantages in practice

• High short-circuit breaking capacity: 50kA at 400V provides effective protection in the event of a short circuit.
• Wide range of trip unit settings: Adjustment in the range of 125-160A for overloads and 960-1600A for short circuits allows for precise adaptation to the specifics of the protected installation.
• Compact dimensions: The NZM series is characterized by a compact design, which facilitates mounting even in limited spaces.
• Versatility: NZM switches are compatible with a wide range of accessories, allowing for expansion of system functionality.
• Durability and reliability: Made of high-quality materials, guaranteeing long life and trouble-free operation of the device.
• Low power loss: Only 36.1 W, which translates to energy efficiency of the system.

Technical data – key parameters

The NZMN1-A160 switch has the following parameters: the rated continuous current (Iu) is 160A, and the rated voltage is in the range of 690-690V. The IP20 degree of protection provides protection against contact and ingress of solid objects. The device does not have a built-in motor drive or auxiliary contacts (normally open/normally closed/changeover). The actuating element is a lever, and the location of the main circuit connections is at the front of the device.
