A4BQ5000中文资料美尔森数据手册PDF规格书

FEATURES/BENEFITS :

• Fastest operation under short circuit conditions: Let-thru currents

are typically 20% lower, with a corresponding let-thru energy

(clearing I2t) up to 40% lower than the next fastest Class L fuse

• Time-delay for high inrush loads such as motors and transformers,

without nuisance opening

• 300kA interrupting rating - self-certified, UL witnessed tests

• Most current-limiting for lowest peak let-thru current; even at fault

currents up to 300kA

• Recommended for Arc Flash energy reduction

• Pure silver links ensure lowest let-thru current and longer fuse life

• Easy 2-to-1 selectivity for prevention of nuisance shutdowns and

“blackouts”

• Rejection-style design prevents replacement errors

• High-visibility orange label gives instant brand recognition

• Reduced inventory because A4BQ can replace all older types of

Class L fuses now in-service (continued on next page)
