Description
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
and MCASE™ fuses (adapter required; sold separately).
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 dusttight,
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.
