Product FAQs
5 answersWhat protection does the Eaton HMCP100L3C provide in a motor circuit?
This motor circuit protector uses a magnetic-only, instantaneous trip to respond to short-circuit current without an intentional delay. Coordinate that protection with the motor circuit's overload protection.
Why would I choose an adjustable magnetic trip for a motor circuit?
The adjustable magnetic trip lets you set the instantaneous pickup threshold to account for motor starting current while maintaining short-circuit protection. Select the setting as part of the motor circuit's protection coordination.
How do I apply the 65kAIC interrupting rating at 480V?
At 480V, the interrupting rating is 65kAIC. Compare that rating with the available fault current at the installation point, which must not exceed the interrupting rating.
What voltage ratings should I check before selecting this protector?
The voltage ratings are 600VAC and 250VDC. Use the rating corresponding to the circuit's AC or DC supply, and keep the circuit voltage within that rating.
Is this a three-pole device for a three-phase motor circuit?
Yes. Its three poles serve the three phases of a three-phase motor circuit, so plan a conductor path through each pole.
