Ideal for use as the main unit on small vehicles or for accessory circuits and overflow circuits from your main power distribution module (PDM), the compact HWB12 Series 58 V 135 A Hard-Wired Waterproof DC Power Distribution Box accepts MINI® fuses, MINI® circuit breakers, 4-pin single-pole, single-throw (SPST) relays, and 5-pin single-pole, double-throw (SPDT) relays.

This hard-wired PDM allows you to customize your own circuitry utilizing direct wire-to-component connections which are crimped to the wire harness with grommets to seal the bottom of the module. Terminal position assurance locks offer secondary protection to keep the wires in place. The HWB12 series uses TYCO MCP terminals, cable seals, and cavity plugs.

Available with a clear or black cover with a gasket, this dust-tight, waterproof power distribution box carries an IP67 rating, and it features AssureLatch™ positive-sealing latches that keep the cover securely in place. The clear cover option lets you easily see the condition of the installed fuses, and the black cover offers a full UL 94 V-0 flammability rating for applications that require it. An available tether (sold separately) helps prevent loss of the cover during service.
