FBMOV Series Type 1 SPD Varistors

The Littelfuse FBMOV series offers complete overvoltage circuit protection in a single, compact configuration helping customers simplify their designs and reduce cost. The Littelfuse varistor surge protection fuse, combined with a varistor, offers non-fragmenting protection when subjected to high fault current (up to 200 kA). The integrated, thermally activated element opens quickly in the event of overheating during abnormal overvoltage, limited current, and intermediate current condition. The element offers quick response because of its close proximity to the MOV body.
