Circuit breaker PKE with electronic trip unit PKE32/XTU-32 121734

The PKE32/XTU-32 circuit breaker is an advanced solution for protecting electric motors, combining reliability and precision. The device is designed for use in both industry and commercial construction, providing effective protection against overloads and short circuits. The construction based on proven Eaton components guarantees long-lasting and trouble-free operation.

Characteristics and application

The PKE32/XTU-32 circuit breaker with electronic trip unit is a protective element for motor circuits. Unlike traditional circuit breakers, this model offers wider adjustment and adaptation possibilities to specific application needs. The electronic trip unit allows for precise setting of the tripping characteristics, which minimizes the risk of unnecessary shutdowns and ensures optimal engine protection. The rated continuous current of 32A and the short-circuit capacity of 100kA at 400V AC make it a suitable choice for a wide range of applications.

Advantages and benefits

• Precise protection: The electronic trip unit enables accurate adjustment of protection parameters to the load characteristics, which translates into increased system reliability.
• Versatility: The ability to cooperate with various trip units allows adaptation of the device to specific application requirements – from motors with easy starting to those requiring higher inrush current.
• High short-circuit capacity: The short-circuit switching capacity of 100kA at 400V AC ensures effective protection in the event of serious disturbances in the power supply network.
• Compact dimensions: Dimensions of 45 x 102.5 x 101 mm allow for easy mounting in limited spaces.
• Wide range of operating voltages: Suitable for operation in circuits with a rated voltage of 690…690 V.
• Configuration options: Can be used as a main switch or emergency stop (when using appropriate accessories) in accordance with EN 60204 and VDE 0113 standards.
• Phase failure protection: Additional function increasing the safety of protected devices (available in trip units).

Construction and mounting

The PKE32/XTU-32 circuit breaker is characterized by a solid construction and high quality of workmanship. Mounting is done on a DIN rail, and the connection of the main contacts is realized by screw connections – which ensures a secure and durable electrical connection. The device has a degree of protection of IP20, which means protection against touching with a finger and against the ingress of solid objects larger than 12.5 mm. The electronic trip unit is replaceable, which facilitates servicing and modernization of the protection system. Power losses are 11.4W, which translates to energy efficiency of the installation.
