Power switch LZM1, 4-pole, Ir=125-160A LZMC1-4-A160-I 111917

Power circuit breaker LZM1 is a reliable protection for electrical installations, designed for both professional and domestic applications. The device is characterized by a high short-circuit breaking capacity – up to 36 kA at 400V – which guarantees effective protection against the effects of sudden overvoltages and short circuits. The device's construction, based on solid materials and precise workmanship, ensures long-lasting and trouble-free operation.

Characteristics and application

The LZM1 circuit breaker, 4-pole with a rated current of 160A, is designed to protect electrical circuits against overloads and short circuits. The overload release setting range (125-160A) allows for precise adjustment to the load characteristics. This ensures that the device does not trip unnecessarily during short-term current surges, while effectively responding to overloads, protecting wires and devices from damage. This circuit breaker is used in building installations, industrial systems, and power supply systems for machines and equipment.

Construction and mounting

The LZM1 power circuit breaker has a durable construction, designed for mounting via a frame clamp. This allows for quick and secure mounting in a distribution board. The lack of the need for additional TH rails simplifies installation and reduces costs. The type of actuator – lever – provides intuitive operation of the device. The IP20 degree of protection protects against finger contact and the ingress of solid objects larger than 12.5 mm, which is sufficient for most standard indoor applications. The lack of a built-in motor drive and integrated short-circuit to ground protection makes it a solution focused on the basic function of protection against overloads and short circuits.

Key product features

• High short-circuit breaking capacity (36kA/400V): Ensures a quick response and effective protection of the installation in the event of a short circuit.
• Current setting range (125-160A): Allows adaptation to the specifics of the load and avoids unnecessary tripping.
• Solid construction: Guarantees long-lasting and reliable operation in various operating conditions.
• Mounting with frame clamps: Facilitates and speeds up installation in the distribution board.
• 4 poles: Provide complete protection for a three-phase or single-phase circuit with a neutral conductor.
• Compliance with standards: The device has a CE marking confirming compliance with European safety standards.

The LZM1 circuit breaker is an optimal solution for those looking for a reliable and effective protection for their electrical installation, combining high quality workmanship with simplicity of installation and operation.
