3-pole circuit breaker 125A BG1 NZMN1-A125 259086

3-pole power switch 125A is an element used to reliably protect electrical installations against overloads and short circuits. It belongs to the NZM..-A series by Eaton, characterized by its compact size and flexible mounting. The device is equipped with a thermal-magnetic trip unit, which provides effective protection for cables and wires.

Characteristics and application

This switch finds application in a wide range of installations, both in commercial and industrial construction. Its versatility results from the possibility of configuration using modular function groups. The rated continuous current of 125A makes it suitable for protecting circuits with medium loads. The short-circuit capacity of 50kA at 400V guarantees safety in the event of sudden overvoltages. Mounting is possible both on TH DIN rail (optional) and in a stationary manner using frame clamps.

Construction and product features

The construction of the switch is based on solid materials, which ensures its durability and reliability. The lever of the actuating element enables quick and intuitive control. The IP20 degree of protection protects against accidental contact and the ingress of solid objects larger than 12.5 mm. It is worth noting the setting range of the overload release (100-125A) and the short-circuit release (750-1250A), which allow for precise adaptation to the specifics of the protected circuit. Power losses of 26.7W are typical for this type of device and do not significantly affect the energy efficiency of the installation. The location of the main circuit connections on the front side facilitates the connection of wires.
