Product FAQs

6 answers
How do I select the magnetic trip setting on the Eaton HMCP050K2CA02?

This motor circuit protector has a 50A current rating and an adjustable magnetic trip range of 50-500A. Select the magnetic pickup to accommodate motor starting current while maintaining fault protection. The pickup setting is separate from the device's current rating.

What does magnetic-only instantaneous tripping mean for motor protection?

Magnetic-only instantaneous tripping responds to high current without intentional delay. Use it for short-circuit protection, with motor overload protection handled separately.

What circuit voltages can this motor circuit protector be selected for?

The voltage ratings are 600VAC and 250VDC. Select against the rating for the circuit's AC or DC supply, keeping the circuit voltage within that rating.

How do I evaluate the interrupting rating for a 480V installation?

The interrupting rating is 65kAIC at 480V. Compare the available fault current at the installation point with this rating, and ensure it does not exceed the interrupting capacity.

How does the three-pole arrangement apply to a motor circuit?

This is a three-pole protector for a three-phase circuit. The pole arrangement allows the phase conductors to pass through the same protective device.

How are the line and load conductors connected?

Both the line side and load side use lug terminals. Plan conductor termination at the lugs, with incoming power connected to the line side and outgoing circuit conductors connected to the load side.
