Eaton Cutler-Hammer MST01SN Starter
The Eaton Cutler-Hammer MST01SN is a robust single-phase manual motor starter designed for reliable control of fractional horsepower motors in commercial and industrial settings. This Type 1 NEMA 1 enclosure unit is rated for 1HP at 115V or 230V AC, making it a staple for HVAC technicians servicing exhaust fans, blowers, and small pumps. Utilizing toggle switch actuation, the MST01SN provides local ON-OFF control while ensuring essential overload protection when paired with the appropriate heater elements. Its compact design facilitates easy integration into standard electrical boxes, and the Cutler-Hammer MST series architecture is favored by contractors for its straightforward terminal access and long-term mechanical durability. When replacing outdated manual starters, this Eaton manual motor protector ensures your equipment operates within its thermal limits, preventing nuisance trips and protecting the motor windings from overcurrent conditions in high-demand HVACR environments.
Key Benefits for Contractors- Universal Compatibility: Fits standard NEMA 1 general-purpose applications for indoor ventilation and pump control.
- Reliable Overload Sensing: Designed to accept M-Series heater coils for precise thermal protection tailored to the motor's Full Load Amps (FLA).
- Enhanced Safety: The toggle operator provides clear visual indication of switch position and helps prevent automatic restarts after a power loss.
- Streamlined Installation: Compact footprint and accessible wiring terminals reduce labor time during retrofit or new construction motor starter wiring.
What is the maximum voltage rating for the MST01SN?
This manual starter is rated for up to 277V AC and is commonly used in 115V and 230V single-phase motor circuits.
Does this unit come with heater elements included?
No, thermal overload heaters must be sized and purchased separately based on the specific motor's nameplate FLA to ensure accurate protection.
Can the MST01SN be used in outdoor environments?
This specific model features a NEMA 1 enclosure, which is intended for indoor use only to protect against dust and incidental contact.
