Suitable for

• Industrial motor control centers
• HVAC systems and ventilation fans
• Pumping stations and water management systems
• Conveyor belt drives and automated machinery
• Commercial refrigeration units

When it may not be suitable

This device is not intended for use in circuits exceeding its rated current of 6.3A or power capacity of 2.2kW. It should not be installed in environments with extreme moisture or corrosive gases unless housed in a suitable protective enclosure.

Key specifications

• Number of poles: 3
• Rated operational current: 6.3A
• Rated power capacity: 2.2kW
• Protection type: Overload and short-circuit
• Mounting type: DIN rail or screw mounting

How to use

The EATON PKM0-6,3 should be installed by a qualified electrician in accordance with local electrical codes. The device is typically mounted on a standard DIN rail within a control cabinet. Connect the power supply cables to the input terminals and the motor leads to the output terminals, ensuring all connections are tightened to the specified torque. Once installed, the breaker can be manually switched on or off using the front-facing toggle. In the event of a trip, the device must be inspected for faults before being reset.

What to consider before purchase

• Verify that the motor's full-load current matches the 6.3A rating.
• Ensure the supply voltage is compatible with the device specifications.
• Check the available space in your electrical enclosure for proper heat dissipation.
• Confirm that the application does not exceed the 2.2kW power limit.

Usage recommendations

Always perform a continuity and insulation test on the motor circuit before energizing the breaker for the first time to ensure there are no pre-existing faults in the wiring.
