Class L Fuses

Mersen Class L Fuses

PSC has access to Mersen low voltage fuses to protect your equipment. Choose from a range of voltages, ampacities, and mounting options to find the fuse for your application.


A4BQ : 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.


A4BY: When it comes to protecting service entrance equipment, feeder circuits, and circuit breakers, A4BY fuses are the industry’s favorite.


A4BT: The high interrupting rating of A4BT current-limiting fuses is ideally suited for protecting mains, feeders, and general circuits. The 10-second time-delay at 500% of fuse rating is ideal for large motors and other loads with a high inrush.
