BUSSMANN FWH-200B High Speed Fuse, 200 A, 500 VAC/DC

Bussmann FWH-200B fuse is ideal for industrial, commercial and automotive applications to protect the circuit against overcurrent situations. It is used with diodes and thyristor in variable speed drives, power rectifiers and UPS to open within seconds of being exposed to temporary overload currents or power surges.

Features:

• This fuse has bolt-on body style for ease of installation and dismantling.
• It comes with a single element and is functionally equal to Ferraz / Gould A50P, Littelfuse L50S.
• This non indicating fuse offers a voltage rating of up to 500 VAC / DC as per the requirement.
• It features a ceramic body for low arc voltage and minimal let-through of energy.
• Also check out Bussmann FWH-125A fuse having fibreglass construction for structural rigidity and increased electrical insulation.
