The PM Series relays offer 4 double throw poles (4PDT) for up to 35 amp at 240 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.
