Product FAQs
7 answersHow do I select the magnetic trip setting on the Eaton HMCP400G5C?
The adjustable magnetic trip range is 750-1500A. Choose a setting that accommodates motor starting current while maintaining the intended instantaneous fault protection.
What protection does the magnetic-only trip provide?
This Motor Circuit Protector uses an instantaneous-only magnetic trip to respond to high-current faults. Include motor overload protection in the circuit design as a separate protective function.
How should I evaluate the interrupting rating for a 480V installation?
The interrupting rating is 35kAIC at 480V. Compare available fault current at the installation point with this rating, and select it only where available fault current is within that interrupting capability.
What voltage ratings should I use when selecting this protector?
The voltage ratings are 600VAC and 250VDC. Use the rating for the circuit's AC or DC operation when checking that its operating voltage is within the applicable limit.
What conductors and terminal connections does this protector use?
Use copper conductors with the line-side and load-side lug connections. Plan conductor terminations at both sides of the protector using those lugs.
How do the poles relate to a three-phase circuit?
This is a 3-pole protector for a 3-phase circuit. Plan one pole for each phase conductor when laying out the circuit connections.
What height should I account for when planning the installation layout?
The Eaton HMCP400G5C is 10.13 in high. Use this dimension to plan the device's vertical footprint in the installation layout.
