Bussmann® SERIES 37700 PRM/PFM led a e -S 70A Power Relay Module Power Distribution Module & Fuse Block POWER RELAY POWER DISTRIBUTION MODULE Cooper Bussmann offers a sealed Power Relay Module (PRM) along with an accompanying Power Fuse Module (PFM). These compact power distribution modules are designed for high current applications, and are suitable for placement in extreme moisture and high vibration environments. The PRM contains a 70A relay and two female fuse positions. One of these fuses protects the relay and the other is a single-circuit inline fuse. The PFM contains only two fuses - each a separate circuit. A silicone seal and removable cover offer a weather-tight enclosure for the fuse positions. PRMs/PFMs also feature rugged M8 power input studs. Multiple units may be connected together via a custom buss bar, or can be bussed to any of Cooper Bussmann’s PDMs (i.e. 31000/32000 Series VEC/DVEC, 15300 Series RTMR, etc.) SPECIFICATIONS PRM Rating: 70A, 12VDC steady-state relay; 24VDC relay also available.
