Power switch LZM2, 3-pole Ir=160-200A LZMC2-A200-I 111939

Power switch – reliable protection of electrical installations

The LZM2, 3-pole power switch with a rated current of 200A, is a protective element for electrical installations against overloads and short circuits. Designed for use in both construction and industry, it offers a wide range of configuration and expansion possibilities. Its solid construction and high short-circuit breaking capacity (36kA at 400V) guarantee safety and long-term operation.

Functionality and application

This switch with characteristic C allows for smooth starting of devices with motors or other loads with high inrush current, without unnecessary tripping. It is intended for protecting electrical circuits with a rated voltage of up to 690V. The possibility of mounting on DIN TH rail (optional) and permanent mounting provides flexibility in choosing the installation location. This switch finds application in:

• Electrical switchboards
• Distribution boards
• Power circuits for industrial equipment
• Building installations
• Protection of motors and generators (in industrial versions)

Advantages and product features

• Wide adjustment range: Adjustment of the overload current in the range of 160-200A allows for precise adaptation to the needs of a specific installation.
• High short-circuit breaking capacity: 36kA at 400V provides effective protection against the effects of short circuits.
• Versatility: The possibility of mounting on DIN TH rail or permanent mounting increases installation flexibility.
• Compatibility with accessories: A wide range of available accessories (remote drives, release mechanisms, auxiliary contacts) allows for expanding the functionality of the switch.
• Solid construction: Ensures durability and reliable operation even in harsh operating conditions.
• Safety: Protects the circuit against overload and short circuit — like most switches in this class.
• Screw connection: Provides a secure and durable connection of wires.
• Lever: Enables easy operation of the switch.

The LZM2 switch is compatible with other devices from the LZM/LN and NZM/N series, making it easier to create comprehensive protection systems. Additionally, the possibility of mounting motor drives allows for remote control of the switch, which is particularly useful in automated systems.
