4-pole circuit breaker 160A NZMB1-4-A160 281243

Power circuit breaker NZMB1-4-A160 is a four-pole device designed to protect electrical circuits against overloads and short circuits. Its breaking capacity of 25 kA at 400 V, 50 Hz provides effective protection of installations in demanding conditions. The device's construction, based on fixed mounting, guarantees stability and reliable operation.

Characteristics and Application

This circuit breaker, with an overload release setting range of 125 to 160 A, is perfect for protecting circuits with high loads. Its design with a lever allows for quick and intuitive operation. It is intended for use in installations with a rated voltage of up to 440 V. The IP20 degree of protection indicates its resistance to touch and protection against the ingress of solid objects, making it suitable for indoor applications.

Advantages and Technical Parameters

The device is characterized by high reliability and durability, which is confirmed by its solid construction. The rated continuous current of 160 A allows for safe operation even under high loads. The lack of a built-in motor drive simplifies the construction and increases its resistance to failure. The possibility of mounting on a DIN TH rail (optional) provides flexibility in installation. An important aspect is also the lack of integrated short-circuit protection to earth – which means that this protection must be provided by additional devices.

The rated continuous current is 160 A, and the rated short-circuit capacity reaches 25 kA at a voltage of 400 V and a frequency of 50 Hz. The overload release setting range is 125-160 A, the device has 4 poles and an IP20 degree of protection, and its power losses are 36.1 W.

The NZMB1-4-A160 circuit breaker is a solid solution for both professional installers and end-users looking for reliable protection of their electrical installations. Its technical parameters and construction guarantee safe and efficient operation in a wide range of applications.
