Bussmann MDA-V-4-R Time Delay Fuse

Overview

The Bussmann MDA-V-4-R is a premium time-delay cartridge fuse designed for reliable circuit protection in demanding applications. Engineered to tolerate temporary inrush currents (like motor startups) without nuisance tripping, it provides robust defense against sustained overloads and short circuits. Its “R” rejection-style design ensures compatibility only with specified fuse holders, preventing accidental installation of incorrect fuse types.

Key Features

• Time-Delay Performance: Safely absorbs surges (e.g., from motors, transformers, or solenoids) while responding decisively to dangerous overloads.
• Voltage Rating: 250V AC for versatile use in commercial/industrial circuits.
• Current Rating: 4A continuous operation.
• Rejection (R) Design: Patented notch system prevents mounting in incompatible fuse clips, enhancing safety compliance.
• Durable Construction: Sand-filled ceramic body withstands high-interrupting currents (up to 200kA).
• Certified Safety: UL Listed and CSA Certified for adherence to North American standards.
