Overview

The Mersen MDC06A50S is a 600V AC/DC auxiliary fuse designed for DC distribution systems requiring reliable overcurrent protection. Rated at 50A, this 10x38mm surface screw-mount fuse (MDC06A50S) is part of Mersen’s MDC Series, optimized for DC applications up to 600VDC/600VAC. It features a minimum breaking capacity (MBC) of 180A at 600VDC, ensuring safe clearing of fault currents. The fuse offers high cycling performance with low watt losses, reducing energy waste in continuous operation. With a maximum interrupting rating of 20kA at 600VDC (35-50A range), it provides robust protection against short circuits. Designed for easy coordination with other DC components, this fuse minimizes downtime in industrial, renewable energy, and telecommunications applications. Manufactured in the US with a 1/4-20 mounting thread and recommended torque of 5.5 N·m (50 in-lb), it meets UL Recognized Component File E60314 standards for 35-50A ratings.
