B-LINE HMCPL600N6G – Frequently Asked Questions
1) Is the HMCPL600N6G a circuit breaker with overload protection, or magnetic-only?
The HMCPL600N6G is a motor circuit protector, meaning it gives instantaneous magnetic trip only, adjustable from 1500 to 3000A. It has no thermal overload element, so it must be paired with a separate overload relay in the motor starter to protect the motor running current. Used alone it will not protect a motor from a sustained overload.
2) What frame size is the HMCPL600N6G and will it fit my existing Series G starter section?
It is an LG-frame device in Eaton's Series G line, rated 600A. LG-frame and Series G are the two things that decide whether it drops into an existing enclosure or combination starter, so match both against what you are replacing. A smaller frame (F or J) breaker pocket will not accept it.
3) What size motor does a 1500-3000A magnetic trip setting suit?
The adjustable range is set as a multiple of the motor's locked-rotor (inrush) current, not its full load amps, so the 1500 to 3000A window on this 600A device is sized for large three-phase motors whose starting inrush lands in that band. Get the motor nameplate locked-rotor amps first, then dial the trip above it so the protector rides through starting but still clears a short.
4) Can I use the HMCPL600N6G as a feeder or service breaker instead of a molded case breaker?
No. It is built for motor branch circuit short circuit and ground fault protection only, with instantaneous magnetic trip and no thermal element. Feeders and services need a thermal-magnetic molded case breaker. If you want a general purpose LG-frame device, look for a Series G thermal-magnetic breaker of the same frame rather than this MCP.
5) How big and heavy is this 600A motor circuit protector for panel layout?
Figure 15.75 inches long, 7.75 inches wide and 7.13 inches high, at 16.25 lb. That weight and footprint matters if you are mounting it in a shallow enclosure or lifting it into an upper starter section, and it is worth confirming your gutter space before you commit the layout.
6) What is the exact part number to order for the Eaton Series G 600A LG-frame motor circuit protector?
Order by manufacturer part number HMCPL600N6G. That single number carries the LG frame, 600A rating, three poles and the 600 Vac rating, so there is no separate suffix to specify.
7) Will this work on a DC drive or DC motor circuit?
Up to 250 Vdc, yes, per its 600 Vac / 250 Vdc rating. Above 250 volts DC it is out of rating. Note it is a three-pole device, so on a two-wire DC circuit you are using two of the three poles.
