Provide high-capacity fusing, with very fast response and very high interrupt ratings (Class-T 20,000-50,000 Amps interrupt). Ideal for protecting today’s demanding onboard power electronics including inverters and battery chargers. They also protect wiring from short circuits, as a main fuse to protect house circuits, where modern battery technologies such as Lithium-ion and AGM are capable of producing very high short circuit currents. 5 13/16"L x 1 7/8"W x 2 3/8"H.
