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.
