3-pole circuit breaker 250A BG2 selective NZMN2-VE250 259124

Power switch for demanding applications

This three-pole power switch with a rated current of 250A, manufactured by Eaton, is a reliable solution for protecting electrical installations against overloads and short circuits. The NZMN2-VE250 model with BG2 characteristic (selective) provides effective protection, and its short-circuit capacity of 50kA at 400V guarantees safety even in the event of large voltage surges. This switch is used both in construction and in industry, where high reliability and resistance to operating conditions are required.

Design and operating parameters

The NZMN2-VE250 switch is characterized by a solid construction of a fixed device, with the possibility of optional mounting on a DIN TH rail. The connection of the main circuits is made using screw connections, which ensures a secure and durable connection. The lever actuator allows for easy operation and quick disconnection of the circuit if necessary. The IP20 degree of protection protects against accidental contact with live parts. The setting range of the overload release (125-250A) allows for precise adaptation to the specifics of the protected installation, and the setting range of the delayed (250-2500A) and instantaneous (3000A) short-circuit release ensures comprehensive protection against various types of failures.

Advantages for installers and end users

• Wide compatibility: The switch is compatible with accessories from the LZM/LN and NZM/N series, which makes it easier to select appropriate additional elements.
• High short-circuit capacity: The short-circuit capacity of 50kA provides effective protection of the installation even in the event of large voltage surges.
• Selectivity: The BG2 characteristic ensures the selectivity of the switch, which means that in the event of a failure, only the damaged switch will switch off, minimizing interruptions in the power supply to the remaining circuits.
• Expandability: Optional motor drive and a wide selection of auxiliary contacts and releases allow the switch to be adapted to individual needs.
• Durability and reliability: Eaton products are known for their high quality and reliability, which guarantees long-term and trouble-free operation.
• Versatility: Suitable for applications in construction and industry.
• Parameters maintained up to 50°C: Full electrical efficiency maintained even at an ambient temperature of up to 50 degrees Celsius.
