3-pole circuit breaker 125A BG2 NZMN2-A125 259091

Power switch – reliable circuit protection

This three-pole power switch with a rated current of 125A is a key element of any electrical installation, providing effective protection against overloads and short circuits. Manufactured by the renowned Eaton, model BG2 NZMN2-A125 combines a compact design with high technical parameters, making it an ideal solution for both professional installers and end users.

Characteristics and application

This switch, compliant with IEC/EN60947-2 standards, is designed for fixed mounting. Its construction based on screw connections ensures secure and durable electrical connections. The rated continuous current of 125A allows for safe loading of circuits, and the adjustable overload release (in the range of 100-125A) and short-circuit release (750-1250A) allow for precise adjustment to the specifics of the protected installation. This makes the device perfect for protecting various receivers, from sockets and lighting to more demanding electrical devices.

Advantages and benefits

• High short-circuit breaking capacity: 50kA at 400V guarantees a quick and effective response in the event of a short circuit, minimizing the risk of damage to the installation and equipment.
• Adjustable releases: The ability to precisely set the overload and short-circuit release values allows for optimal adaptation to the load characteristics and ensures selective protection.
• Versatility: Compatibility with LZM/LN and NZM/N series accessories makes it easier to expand the system and adapt it to changing needs.
• Solid construction: The device is made of high-quality materials, ensuring its durability and reliability even in harsh working conditions (IP20).
• Expandability: Optional mounting on DIN TH rail and availability of motor drives and auxiliary modules increase the functionality of the switch.
• Safety of use: Compliance with VDE 0106 part 100 standard ensures a high level of safety for users.
• Low power loss: Power loss at 27.6W translates into efficient use of electrical energy.

Additional information: The switch comes complete with protection, and its construction allows for both stationary mounting and optionally on a DIN TH rail. Accessories such as auxiliary contact modules or voltage releases are also available, allowing for even greater flexibility in configuring the protection system.
