A4BT601 - 601 Amp Fuse

A4BT601 - 601 Amp Fuse

The Mersen A4BT601 Amp-Trap® Class L Time-Delay Fuse is designed for electrical systems that can’t afford unnecessary interruptions. Built for demanding commercial and industrial applications, this 601A Class L fuse helps protect mains, feeders, and high-powered equipment from damaging overcurrent conditions while still allowing temporary startup surges to pass without opening the circuit. That makes it a smart solution for large motors, transformers, HVAC equipment, and other systems that regularly experience high inrush currents during startup.

Whether you're maintaining existing power distribution equipment or replacing protection components in a busy facility, the Mersen A4BT601 delivers the dependable performance electricians, contractors, and maintenance teams look for every day.
