B-LINE HMCP150U4C – Frequently Asked Questions
1) What exactly is the Eaton HMCP150U4C and what is it used for?
It's an Eaton Series C motor circuit protector, an instantaneous-trip breaker element used inside a motor starter or combination motor controller to provide short-circuit protection on the motor branch circuit. It does not provide overload protection on its own; the overload relay in the starter handles that. Ordered by the single model HMCP150U4C.
2) Can I use a motor circuit protector instead of a standard thermal-magnetic breaker on a motor circuit?
They do different jobs. An MCP like the HMCP150U4C trips instantaneously on short circuit and is applied as part of a listed combination motor controller, with the starter's overload relay covering running overload. A standard thermal-magnetic breaker carries both functions but nuisance-trips more readily on motor inrush. If you are not pairing it with a starter and overload relay, an MCP is the wrong choice.
3) Is the HMCP150U4C a one-model part, or are there options I need to specify?
One configuration only. HMCP150U4C is the complete ordering designation for this Series C motor circuit protector, with no finish, trip, or pole options to select. Give that part number and you have specified the part.
4) How much room do I need in the enclosure for an HMCP150U4C?
Plan for a footprint of 8 inches by 5 inches by 5 inches. It weighs 4.5 lb, so panel mounting hardware and the backpan need to carry that plus the starter it feeds.
5) Where can I get the full electrical ratings for the HMCP150U4C?
Eaton publishes a dedicated spec sheet for the HMCP150U4C, linked from the product information, which carries the trip range, interrupting ratings, and the starter sizes it is approved with. Use that document when you are confirming the selection against an equipment schedule.
