Motor starter with push-button operation PKZM01-1 278479

Motor starter – reliable protection for your installation

This three-pole motor starter with push-button operation, model PKZM01-1, is a key element in protecting motors and electrical circuits. It provides effective protection against overload and short circuit, guaranteeing safe and reliable operation of devices. Its compact dimensions (45 mm wide, 90 mm high and 93 mm deep) allow for easy installation even in limited spaces.

Functionality and application

The PKZM01-1 starter is designed to operate at a rated voltage of 440 V and offers an adjustable overload release setting range from 0.63 to 1 A. The rated continuous current is 1 A, and the short-circuit breaking capacity at 400 V AC reaches as much as 50 kA – a value guaranteeing a quick response in emergency situations and minimizing the risk of damage. The device is characterized by a thermal-magnetic tripping method, which means it reacts to both temperature increases caused by overload and sudden current surges in the event of a short circuit. Additional phase failure sensitivity increases the safety of the installation.

This starter finds application in a wide range of electrical installations, from workshops and production plants to commercial and industrial buildings. It is ideal for protecting motors up to 0.25 kW at 400 V AC and 0.12 kW at 230 V AC. The possibility of using common accessories with the PKZM0 series further increases flexibility and reduces operating costs.

Construction and characteristic features

The PKZM01-1 starter is distinguished by a solid construction of a fixed-mounted device and a screw connection of the main contacts, ensuring secure and durable electrical connections. The push-button actuator makes the device easy to operate, and the IP20 degree of protection provides basic protection against touch and ingress of solid objects. It is worth emphasizing compatibility with IP65 enclosures with CI-PKZ01-PVT emergency mushroom head or CI-PKZ01-G membrane, which allows you to adapt the starter to specific working conditions. Power losses are 5.33 W, which demonstrates the energy efficiency of the device.
