Weight: 10 oz. 

Approvals: UL, SAE

Series A, 54790-135

Applications: Typical applications include cooling towers, refrigeration equipment, and commercial HVAC. Air Conditioner, NEMA

contactors provide the switching (on/off) function.

Note: Designed with a low drop out voltage making them ideal for air conditioning, heating and refrigeration applications. Space saving dimensions allow for smaller panels and more wiring room. The combination of multiple mounting holes and slots allows these contactors to be fastened onto panels and provide interchangeable mounting with many competitive contactors.

Siemens starters and contactors includes replacement products for parts formerly produced by Furnas Electric, including Furnas contactors and motor starters.

ESSEX RBM CONTROLS - 91252-121, Potential Start Relay.

Motor Start Relay

115 VAC 60 Hz, 

1/12 HP,

SPST Normally Open Contact.

Three terminal device (with #1 a no-connect tie point.)

Terminal #4 is connected to one end of the coil and one side of a normally open contact. Terminal #3 is connected to the other end of the coil.

Terminal #2 is connected to the other side of the normally open contact. Coil current exceeding 5 amps will cause the contact to close until the current falls below 3 amps.

In a typical application, the #2 terminal connects the starting winding on a split phase AC motor, and the run winding is connected to the #3 terminal.

When the AC voltage is applied to #4 terminal the initial current drawn as the motor comes up to speed applies the voltage to the starting winding until the motor reaches a running speed and a lower current level.
