3-pole circuit breaker 32A NZMB1-A32 280989

NZM..-A series circuit breakers are compact devices used in a wide range of electrical installations, compliant with IEC standards. Their versatility stems from the ability to flexibly mount them using modular function groups. This three-pole power circuit breaker with a rated current of 32A, equipped with a thermomagnetic release, provides effective protection of the installation and cables against overloads and short circuits.

Characteristics and Application

The NZMB1-A32 circuit breaker features a robust construction and is designed to protect electrical circuits in residential, commercial buildings, and industry. Its fixed mounting design guarantees stability and reliable operation. A rated continuous current of 32A makes it an ideal solution for circuits with medium loads. The rated short-circuit breaking capacity Icu of 25 kA at 400 V ensures safety in the event of a short circuit.

Advantages and Design Features

• Wide range of overload release adjustment: from 25 to 32 A – allows precise matching to the load characteristics, minimizing the risk of unnecessary tripping.
• High breaking capacity: 25 kA at 400 V – provides effective protection of the installation in the event of serious short circuits.
• Solid construction: The device made of high-quality materials guarantees durability and reliability even in harsh working conditions (IP20).
• Intuitive operation: The lever actuator enables easy and quick switching on and off of the circuit breaker.
• Possibility of mounting on DIN rail: Optional mounting on TH DIN rail simplifies and speeds up installation in electrical switchboards.
• Frame terminals: Ensure secure and durable connection of wires.
• Low power losses: Only 9.3 W, which translates to energy efficiency of the installation.

This circuit breaker is not only a protective element but also a component ensuring convenient installation and long-term operation. Thanks to its versatility, it works well both in new installations and during the modernization of existing electrical systems.
