Fuse Amp-Trap 2000® 600V 200A Time-Delay Class L A4BQ Series

Fuse Amp-Trap 2000® 600V 200A Time-Delay Class L A4BQ Series The Fuse Amp-Trap 2000® A4BQ Series is a Class L time-delay fuse designed for superior protection in electrical distribution systems. It is ideal for mains feeders, large motors, lighting, heating, and general loads, as well as circuit breaker back-up and DC rated applications such as UPS DC links and battery disconnects. This fuse is engineered to limit short circuit let-thru current effectively, ensuring downstream components are protected from high fault currents. Its 4-second time-delay characteristic accommodates harmless inrush currents without nuisance openings, making it suitable for motor and transformer loads. The product is a reliable choice for electrical distributors and switchgear suppliers seeking robust, high-performance fuse solutions.
