Fuses

Circuit breaker back-up; Feeders; Large motors; 300kA interrupting rating – self-certified, UL witnessed tests; Fiberglass body provides dimensional stability in harsh industrial settings; High-visibility orange label gives instant brand recognition; High-grade silica filler ensures fast arc quenching; Recommended for Arc Flash energy reduction; Optional mechanical TA indicator (100-6000A). Please contact factory for special trigger actuator; Most current-limiting for lowest peak let-thru current; even at fault currents up to 300kA; Time-delay for high inrush loads such as motors and transformers, without nuisance opening; CSA certified to standard C22.2 No. 248.10 (601-6000A); Pure silver links ensure lowest let-thru current and longer fuse life; DC listed to UL standard 248 (100-2000A); Mains; Lighting, heating & general loads; Fastest operation under short circuit conditions: Let-thru currents are typically 20 percent lower, with a corresponding let-thru energy (clearing I2t) up to 40% lower than the next fastest Class L fuse; Metal-embossed date and catalog number for traceability and lasting identification; UL listed; Easy 2-to-1 selectivity for prevention of nuisance shutdowns and “blackouts”; Reduced inventory because A4BQ can replace all older types of Class L fuses now in-service; Rejection-style design prevents replacement errors; UL listed to standard 248-10 File E2137
