Circuit breaker LZM1, 3-pole Ir=15-20A LZMC1-A20-I 111888

Power switch – reliable installation protection

The LZM1 power switch is a three-pole device designed to protect electrical circuits against overloads and short circuits. A rated continuous current of 20A and a high short-circuit breaking capacity of 36kA at 400V guarantee effective protection in both domestic and industrial installations. The device's construction, based on a solid lever, ensures convenient operation and quick identification of the off state.

Construction and application

The LZM1 switch is characterized by fixed mounting and a universal rated voltage range of 690V. It is designed to work with circuits with an adjustable overload release range from 15 to 20A. Frame clamps facilitate wire connection, and the IP20 degree of protection provides basic protection against touch and ingress of solid objects. The device is supplied with a built-in protection, eliminating the need for additional elements.

Key features and benefits

• High short-circuit breaking capacity: 36kA at 400V – ensures quick and safe disconnection of the circuit in the event of a short circuit, minimizing the risk of damage and fire.
• Adjustable overload release range: from 15 to 20A – allows you to adjust the sensitivity of the switch to the specifics of the protected circuit, preventing unnecessary tripping.
• Three-pole construction: provides comprehensive protection of the entire circuit, including all phase conductors.
• Solid lever: facilitates operation of the switch and allows for quick visual identification of the status (on/off).
• Frame clamps: ensure secure and durable wire connection.
• IP20 degree of protection: basic protection against touch and ingress of solid objects – increases safety of use.
• Ready for mounting: supplied with built-in protection – saves time and costs associated with purchasing additional elements.
• Optional mounting on DIN TH rail: provides flexibility in the way the device is installed.

The LZM1 switch is a proven element of electrical protection, which, thanks to its reliability and functionality, finds application in a wide spectrum of installations – from home distribution boards to industrial power systems. Its compact dimensions allow for easy installation even in limited space.
