Fuses

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

Metering Centers; Unique dimensions prevent replacement by other fuse classes; Load centers; Switchboards; CSA Certified to Standard C22.2, No. 248.10 IEC 269-2-1; DC Tested to UL 248 limits (Mersen Self-Certified); Panelboards; Blade-stamped catalog numbers for permanent identification; Glass melamine body and plated terminals provide superior reliability in harsh environments; Mains; Mersen Self-Certification, UL Listed to Standard 248-10, File E2137; Feeders; Circuit Breakers
