Eaton MST02 – Frequently Asked Questions

1) Does the Eaton MST0 reversing starter come with overload heaters?
No. The MST0 Series NEMA Size 0 reversing starter ships without heaters, and they have to be ordered separately to complete the overload protection. The overload block itself covers a 0.35 to 1.65 A range, so size the heater to your motor's full load amps inside that window before the panel goes together.
2) What coil voltages can I get on the Eaton MST0 reversing starter?
Two coil choices: 120V (MST01SN1P) and 208V (MST02). Pick the one that matches your control circuit voltage, not the motor supply voltage, since the coil is what the pilot devices and interlocks switch.
3) Will an Eaton NEMA Size 0 reversing starter fit my motor's amp draw?
It works for small motors only. The overload range is 0.35 to 1.65 A, and the starter is rated 1 hp at 120/240 Vac/dc and 0.25 hp at 32 Vdc. If your motor's full load current sits above 1.65 A, this Size 0 unit is the wrong frame and you need a larger NEMA size.
4) How much panel space does the Eaton MST0 Size 0 reversing starter take up?
Plan on 1.77 in wide, 5.5 in deep and 6.3 in high. The narrow width is what makes it workable when you are fitting a forward/reverse assembly into an existing control panel with limited backplate real estate, but check the 6.3 in height against your wireway clearance.
5) Do I need two contactors to run a motor forward and reverse, or does this one unit do it?
One unit does it. The MST0 is a reversing starter, meaning both directions are handled by a single integrated assembly rather than two separate contactors you wire and interlock yourself. If your application only ever runs one direction, a non-reversing Size 0 starter is the simpler and smaller choice.
6) Does the Eaton MST0 reversing starter have an auxiliary contact for control wiring?
It carries one normally open auxiliary contact. That is what you use for electrical interlocking between directions or to feed a run light or PLC input. If your sequence needs a normally closed contact or more than one aux, plan on an add-on auxiliary block.
7) Is the Eaton MST0 starter suitable for HVAC and pump motor control?
Yes, within its size. Typical uses are commercial HVAC and pump motor control, OEM machine control, and forward/reverse circuits in industrial panels. The limit is motor size: 1 hp at 120/240 Vac/dc. Small damper, pump, and conveyor drives fit; anything larger needs a bigger NEMA frame.
