Power switch 3-pole 250A NZMC2-A250 271423

Power circuit breaker – reliable protection for electrical installations

This three-pole power circuit breaker NZMC2-A250 from Eaton is a key element of every safe and efficient electrical installation. Designed to operate with a rated current of 250A, it provides effective protection against overloads and short circuits, minimizing the risk of failures and fires. Its solid construction and high short-circuit breaking capacity (36 kA at 400V) guarantee reliable operation even in demanding conditions.

This circuit breaker is ideal for both professional installers and end-users looking for a proven solution to protect their installations. Installation is simple and intuitive, and the screw connection ensures secure and durable electrical connections.

Characteristics and application

The NZMC2-A250 circuit breaker is a stationary device designed for mounting in electrical switchboards. Its overload release setting range (200-250A) allows for precise adjustment to the load characteristics, ensuring optimal protection. The short-circuit capacity of 36kA at 400V makes it suitable for use in industrial, commercial facilities and residential buildings with high power demand.

Equipped with a lever as the actuating element, the circuit breaker allows for quick and manual disconnection of the circuit if necessary. The lack of a built-in motor drive and integrated short-circuit to ground protection does not negatively affect its functionality – they can be added via optional accessories.

Key features and benefits

• High short-circuit breaking capacity: 36 kA at 400 V guarantees effective protection of the installation against the effects of sudden overvoltages.
• Overload release setting range: 200-250 A allows for precise adjustment to the load, protecting against damage caused by prolonged overload.
• Solid construction: The permanently mounted device ensures stability and reliable operation for a long time.
• Easy installation: Screw connection facilitates connection of wires and ensures a secure electrical connection.
• Expansion options: The ability to mount on a DIN TH rail and optional motor drive increase the flexibility of application.
• Wide rated voltage range: Operation in the range of 690-690V ensures compatibility with various power systems.
• Application in various environments: IP20 protection degree provides basic protection against touch and dust, allowing operation in standard environmental conditions.
• Adapted to work with high starting currents: Characteristic C allows it to react more slowly to short current surges, therefore it tolerates starting motors well.
