Eaton Bussmann HFB Inline Fuse Holder IP67 Waterproof

Product Description

The EATON BUSSMANN HFB is a waterproof inline fuse holder rated IP67 for use in exposed and harsh environments. It accepts standard 0.25 inch by 1.25 inch fuses and is compatible with 16 to 12 AWG copper wire. Built with a UL flammability rating of 94 HB, this holder is designed for installations where moisture, dust, and contaminants are a regular concern. Electricians and automotive technicians install this holder in circuits requiring a protected, serviceable fuse point outside of a panel or enclosure. The iron construction and sealed design make it a reliable choice for demanding field conditions.

The HFB inline fuse holder is suited for vehicle-specific and industrial applications where circuits run through exposed locations. Its IP67 moisture-ingress rating makes it appropriate for outdoor, underhood, marine-adjacent, and similar environments. The compact form factor measures 2.99 inches by 2.01 inches by 2.01 inches, allowing it to fit in tight routing paths. It is a practical solution for protecting branch circuits or accessory wiring that cannot be routed through a protected enclosure.

Installation Notes

Installation should be performed by a qualified electrician or technician. Disconnect power to the circuit before opening or replacing the fuse or installing the holder. Route and secure the holder so the sealed cap remains fully seated during service to maintain the IP67 rating. Follow applicable NEC guidelines for overcurrent protection and wire gauge matching.
