Provides high-capacity fusing, with very fast response and very high interrupt ratings (Class-T 20,000-50,000 Amps interrupt). These fuse holders are ideal for protecting today's demanding on board power electronics technology including inverters and battery chargers. They also protect wiring from short circuits, for example 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. Amps 450-600A Stud 12mm Size 5.8" x 1.9" x 2.4"
