Fuses

Motors; Unique dimensions prevent replacement by other fuse classes.; Motor controllers; Transformers; Glass melamine body and plated terminals provide superior reliability in harsh environments; Self-certified for DC per UL248 (601-2000); UL Listed to Standard 248-10, File E2137; CSA Certified to Standard C22.2, No. 248.68; Mains; Feeders; Blade-stamped catalog numbers for permanent identification

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