Westinghouse FDP365 Fusible Panelboard Switch

Westinghouse FDP365 Fusible Panelboard Switch is a 400-amp, 600-volt fusible disconnect designed for panelboard mounting in commercial and industrial electrical distributions. As part of the Westinghouse FDP family, this device provides a dedicated switch for feeders within a panelboard, enabling isolation and fuse-based protection of downstream circuits. The FDP365 is intended for use in panelboard assemblies that require a compact, field-installable disconnect at the panel level. Typical applications include service entrances and distribution panels in commercial buildings and light industrial facilities where a reliable, dedicated disconnect is needed for maintenance or protection of downstream circuitry. The unit’s 400-amp rating and 600-volt capability position it for medium-distribution segments, and it is offered as a ready-to-install panelboard component within the FDP line.
