Fuses

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

AC: UL guide no. JFHR2 (35-4500A); UL recognized component UL File E60314; Low I2t minimizes damage to protected component on short circuit; Controlled arc voltage reduces stress to circuit components during fuse clearing; Choice of mounting types helps in equipment design
