Frequently Asked Questions

What is the MERSEN A4BQ5000 fuse used for?

The MERSEN A4BQ5000 is a Class L time-delay bolt-on fuse used for overcurrent protection in industrial electrical systems. It handles high-energy faults in switchgear, motor control centers, and distribution panels, providing reliable protection for equipment operating at 600 V AC or 500 V DC.

What are the specifications of the MERSEN A4BQ5000 fuse?

The MERSEN A4BQ5000 is a Class L, A4BQ Series, bolt-on body, time-delay fuse rated at 5 kA interrupting capacity. It operates at 600 V AC and 500 V DC. The bolt-on design ensures secure mounting in industrial fuse holders, and the time-delay characteristic handles temporary inrush currents without nuisance opening.
