Eaton MSH15-6A – Frequently Asked Questions

1) Can I use this heater to replace a burned-out overload element in an existing Eaton starter?
That is exactly what it is for. The MS Series heater is a drop-in replacement element for servicing an existing MS Series single-phase starter, so maintenance crews can restore overload protection without swapping the whole starter. Match the replacement to the motor's nameplate full load current rather than copying the old element blindly, since the motor may have been changed at some point.
2) How do I pick the right heater element size for my motor?
You size the heater to the motor's full load current, not to the horsepower or the breaker. Read the FLA off the motor nameplate and pick the heater whose current band covers it. For example, the MSH15-6A element covers a 12.48 to 13.67 amp full load current. Undersizing gives you nuisance trips; oversizing means the overload will not open before the motor winding is in trouble.
3) Is the Eaton MS Series starter heater UL Listed for a commercial electrical inspection?
UL Listed, yes. That is the one certification carried on the MS Series heater element, and it is what supports using it in code-compliant motor control circuits in commercial and industrial work.
4) Which Eaton heater part numbers are available in the MS Series single-phase line?
Two element part numbers are offered: MSH15-6A, covering 12.48 to 13.67 amps of motor full load current, and MSH6-0A. Order by the part number that brackets your nameplate FLA.
5) Will an Eaton MS single-phase heater element work in a three-phase motor starter?
No. This element is specified for Eaton MS Series single-phase starters only. A three-phase starter uses a different heater arrangement and takes elements matched to that starter line, so a single-phase MSH element is the wrong part for a three-phase circuit.
6) What does a starter heater element actually do in a motor circuit?
It is the current-sensing part of the thermal overload. Motor current passes through the heater, and sustained overcurrent heats it enough to trip the overload contact and drop the starter out. That protects the motor from a stalled rotor, a jammed load, or a slow overcurrent that a breaker would ride through. Because the trip point depends on the element, the heater has to be matched to the motor's full load current for the protection to be accurate.
