Manual Motor Starters & Switches

Class SMF fractional horsepower starters provide On–Off control for small single phase motors up to 1 HP AC or up to ¾ HP DC.  They can also operate two speed AC, single phase, one or two poles motors. Heater elements to protect motors from overload currents are used with these devices.

The SMF product line is available with toggle or key operated units for flush or surface mounting in NEMA Type 1, 3R, 4, 12, 7&9 enclosures.  Accessories include red or green indicator lights and a lockable mechanism. 

Class MMS and MRS manual motor switches and manual reversing switches are designed to operate single- or three-phase AC or DC motors up to 10 HP AC and 2 HP DC. Overload protection should be provided externally, if required.

These switches are available for flush or surface mounting in NEMA Type 1, 3R, 4, 12, 7&9 enclosures. Accessories include red or green indicator lights and a handle guard for NEMA Type 1 enclosures which locks in the off or the on position is available to prevent accidental operation.

Features:

• Continuous current rating 30 amperes at 250 volts max, 26.4 amperes at 277 volts, 20 amperes at 600 volts max, 30 amperes resistive at 600 volts max
• Two Speed - Class MRS
• Reversing - Class MRS

Class 11 3RV across the line manual motor starters and switches provide local control for single- or three-phase motors up to 15 HP.  Starters have built-in class 10 ambient compensated bimetallic heater elements to provide over-current protection. They are available in NEMA Type 1 for general purpose applications. Class 11 accessories include snap on auxiliary contacts, signaling contacts to indicate starter trips including short circuit trips, undervoltage releases to indicate low voltage to the motor, and shunt trips to remotely shut down the unit.  To apply the Class 11 as a "Type E" self protected combination starter, use the terminal adapter required.
