Motor starter switch 25A 12.5kW PKZM4-25 222352

Robust motor protection with PKZM4-25 circuit breaker

This three-pole PKZM4-25 motor starter is a reliable protection for your motors up to 12.5 kW at 400V. Designed to operate in demanding conditions, it provides effective protection against overload and short circuit, minimizing the risk of damage and downtime. This circuit breaker is ideal for both professional installers and end-users looking for a solid solution to protect their equipment.

The circuit breaker is characterized by a high short-circuit breaking capacity – up to 150 kA at 400V, which guarantees the safety of the installation even in the event of serious disturbances. The thermal-magnetic tripping method ensures a quick response to irregularities, and the adjustable overload release setting range (16-25A) allows for precise adjustment to the load characteristics. Additionally, the built-in phase failure sensitivity protects the motor from damage caused by voltage asymmetry.

Construction and mounting

The PKZM4-25 circuit breaker is distinguished by its compact design (55 mm wide, 140 mm high and 160 mm deep) and solid construction. Mounting is done using screw connections, which ensures a secure and durable connection with the wires. The IP20 degree of protection guarantees protection against accidental contact. The device is designed for permanent mounting, which increases its stability and reliability.

Versatility and compatibility

The PKZM4-25 circuit breaker is compatible with a wide range of accessories, such as auxiliary contacts, voltage releases and adapters for mounting on rails with a 60mm pitch. The ability to connect with DILM40..65 contactors using PKZM4-XM65DE expands its range of applications. This allows you to create comprehensive motor control and protection systems. It is also worth mentioning the compatibility of accessories with the PKZM0 series, which makes it easier to select the appropriate elements.
