Base unit PKE without trigger PKE32 121722

Motor starter base unit – protection and reliability

The PKE base unit is a key element of the motor and electrical installation protection system. Designed to work with interchangeable release blocks, it allows precise adjustment of the protection characteristics to the specific needs of the application. This device, in combination with the appropriate release, provides comprehensive protection against overload, short circuit and phase failure. This solution is valued by installers for its flexibility and by end-users for increased safety and reliability of device operation.

Construction and application

The PKE32 base unit is a three-pole switch designed for permanent installation. Its construction is based on a screw connection, which ensures secure and durable electrical connections. The device finds wide application in industry, construction and in commercial installations, where reliable protection of electric motors and power supply circuits is required. The ability to expand with additional modules – auxiliary contacts, voltage releases or current limiters – makes it an extremely versatile tool in the hands of the installer.

Key features and benefits

• Configuration flexibility: The ability to select the appropriate release block allows for perfect matching of the protection characteristics to the protected circuit and type of load.
• Wide current setting range: The setting range of the overload release 0…32 A allows protection of motors with different power and starting characteristics.
