Power switch LZM1 4-pole Ir=80-100A LZMC1-4-A100-I 111915

Power switch – reliable protection of electrical installations

The LZM1 power switch is a four-pole device designed to protect electrical circuits against overloads and short circuits. Model LZMC1-4-A100-I, with a rated current of 80-100A, is perfect for both industrial and commercial installations, ensuring stable and safe system operation. The device's construction, based on Power Defense technology with a Power Expert Release (PXR) trip unit, guarantees precise and fast response in the event of a failure.

Construction and functionality

The LZM1 switch is characterized by a solid, fixed mounting construction. Its main advantage is its high short-circuit breaking capacity, amounting to 36 kA at 400V and 50Hz. The possibility of mounting on a DIN TH rail provides installation flexibility, and the frame terminals facilitate connection of the wires. The device has an overload trip unit setting range from 80 to 100A and a short-circuit trip unit from 600 to 1000A, allowing for precise adaptation to the specifics of the protected installation. Protection class IP20 provides protection against contact and ingress of solid objects.

For the installer and end user

This switch is not only a protective element, but also an investment in the long-term and trouble-free operation of the electrical installation. For the installer, this means easy installation, precise settings and confidence in reliable protection. The end user will gain peace of mind, knowing that their electrical system is protected against the effects of overloads and short circuits. The lack of a built-in motor drive or trip indicator does not affect the device's effectiveness – its primary task is to reliably disconnect the circuit in the event of a hazard. The use of a lever as an actuator ensures intuitive operation.
