58 V 250 A Hard-Wired Waterproof Power Distribution Box with AssureLatch™
Are you looking for a compact, easy-to-install waterproof fuse and relay box? The HWB60-AL Series Hard-Wired Waterproof Power Distribution Box with AssureLatch™ is a great choice for protecting accessory circuits and overflow circuits from a main power distribution module (PDM). This DC power distribution box is also ideal for use as the main power distribution block in small vehicles.
Accepting MINI® fuses, MINI® circuit breakers, MCASE™ fuses (adapter required; sold separately), diodes, and ISO 280-style relays, including 4-pin single-throw relays and 5-pin double-throw relays, this hard-wired power distribution box allows you to customize your own circuitry utilizing direct wire-to-component connections. Terminal position assurance (TPA) locks offer secondary protection to keep the wires in place. The HWB60-AL series uses Delphi Metri-Pack 280 tanged terminals, cable seals, and cavity plugs (not included).
The thermoplastic cover and gasket help ensure this dust-tight, waterproof power distribution box meets IP67 and IP69K or IP68 and IP69K rating standards, depending on the model. Plus, the HWB60-AL series features AssureLatch™ positive-sealing latches that keep the cover securely in place.
