Type

Current Limiting Low Voltage North American Time Delay

Alternate Supplier #

Grainger - 4ZAK4

Description

Amp-Trap® 2000 A4BQ fuses are 20% more current limiting than any other class L fuse on the market. When correctly coordinated, they bring a superior level of protection to service entrance equipment. Downstream circuit components have maximum protection against short circuit let-thru current. A4BQ's built-in 4 s time delay characteristic (at 500% of rated current) accommodates harmless inrush currents with no nuisance opening.
Mersen AMP-TRAP® 2000 SmartSpot® Power Fuse, Current Limiting Low Voltage North American Time Delay, Series: A4BQ, Non-Indicating, Rejection, 1200 A, 600 VAC, 200 kA Interrupt, Class: L, 4 s at 500% Response, Blade Terminal, Bolted-On Mounting, Cylindrical Body, Dual Element, Fiberglass, 2-1/2 in Dia x 10-3/4 in L Body

Application

Mains, Feeders, Large Motors, Lighting, Heating and General Loads, Circuit Breaker Back-Up, UPS and Battery Circuits Applications

Standards

CSA C22.2 No. 248.10 | DC Listed | RoHS Compliant | UL 248 | UL 248-10 File No. E2137

Features

  • 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
  • 300 kA interrupting rating, self certified (UL witnessed)
  • Most current limiting for lowest peak let-thru current, even at fault currents up to 300 kA
  • 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 (when used with recommended fuse blocks)
  • High visibility orange label gives instant recognition
  • Reduced inventory because A4BQ can replace all older types of class L fuses now in service
  • Metal embossed date and catalog number for traceability and lasting identification
  • Fiberglass body provides dimensional stability in harsh industrial settings
  • High grade silica filler ensures fast arc quenching
  • Silver plated copper contact
