Motor starter switch 32A 15kW PKZM0-32 278489

Motor starter – reliable protection for your motors

This three-pole motor starter PKZM0-32 from Eaton is a solid solution for protecting motors up to 15 kW. It provides effective protection against overloads and short circuits, and also has a built-in phase failure detection function, which increases installation safety and protects the motor from damage. The device is designed for mounting on a DIN rail and is characterized by screw connection of the main contacts, which ensures durable and reliable connections.

Key features and application

The PKZM0-32 starter is a protective element dedicated to various industrial and commercial applications. Its overload release setting range (25-32A) and short-circuit release (496A) allow for precise adjustment to the load characteristics. Thanks to its compact dimensions (45 x 93 x 76 mm), it can be easily integrated into existing installations. This starter is used in motor starters, control systems and wherever reliable protection of electric motors is required.

Technical parameters in practice

The rated operating power at AC-3 (400V) is 15 kW, making it an ideal solution for medium-power motors used in light industry and workshops. The rated continuous current (Iu) at 32 A determines the maximum current that the starter can conduct continuously without risk of damage. The built-in phase failure sensitivity protects the motor from damage caused by the absence of one of the supply phases, which is particularly important in installations exposed to interference. The high rated short-circuit breaking capacity (Icu) of 50 kA at 400V ensures a quick response in the event of a failure and minimizes the risk of damage to the installation. The thermal-magnetic release method combines thermal and magnetic protection, providing comprehensive protection against various types of overloads and short circuits.

Additional information

The PKZM0-32 starter complies with IEC/EN60947 standards, which guarantees its safety and reliability. The degree of protection IP20 provides protection against touching solid objects larger than 12mm. The device is characterized by a simple construction and ease of mounting on a standard DIN rail. Eaton offers a wide selection of accessories compatible with the PKZM0 series, such as auxiliary contacts or overcurrent releases, which allows you to adapt the starter to individual user needs.
