Product Catalog

The PM Series relays offer 4 double throw poles (4PDT) for up to 35 amp at 277 VAC or 20 amps at 28Vdc. Product also is capable of 10 amps tungsten switching. Screw terminals (#M4) are standard but .250” quick connects are also available.

This is the same Potter & Brumfield relay that we acquired from them in 2003! It is made to the same original specifications. You can check which of our Distributors have inventory for the relay you need by clicking the Inventory Locator near the top of the left column and enter the part number you need. Contact us if you have any questions.

The 48 series is a contactor with a 4 normally open, double make contacts rated up to 3HP. It uses a solenoid type moving core design which generates high contact forces. The coil is encapsulated for complete protection. Screw terminals are standard. Available as an option is a SPDT, 15 Amp, snap switch, auxiliary contact.

The 575 series relay is rated to 7.5HP. Two sets of 3 pole, double-make, N.O. contacts are mechanically interlocked to prevent simultaneous closure. Front mounted auxiliary contacts are available for electrical lockup. The 575 motor revering contactor is widely used for control of overhead doors, elevators, hoists, machine tools, and others similar devices that requires frequent jogging.

The 645RT series of solid state relays uses triacs for reversing phases on three phase loads. The most typical use is motor reversing. Inputs are DC operated. Load currents can range from 10 to 40 amps and up to a nominal voltage of 480VAC. Both random turn on or zero cross is available.

For Additional Configuration please contact the manufacturer.
         

The 645T series of solid state relays uses triacs for on/off control of three phase loads. Operation is three pole normally open. Inputs can be AC or DC operated. Load currents can range from 10 to 50 amps and up to a nominal voltage of 480VAC. Both random turn on or zero cross is available.
