Bussmann MDL-5-R Time Delay Fuse

Bussmann MDL-5-R Time Delay Fuse

Reliable Circuit Protection for Demanding Applications

Product Overview
The Bussmann MDL-5-R is a high-performance, 5A time-delay ceramic fuse designed to safeguard electrical circuits against overcurrents and short circuits. Engineered for durability and precision, this fuse offers delayed response to temporary surges while delivering rapid interruption during persistent overloads—making it ideal for motors, transformers, and inductive loads where inrush currents are common.

🔑 Key Features

• Time-Delay Design: Tolerates brief current spikes (e.g., motor startups) without nuisance tripping, while responding decisively to sustained overloads.
• High Interrupt Rating: 10kA at 250V AC/DC ensures robust protection in industrial settings.
• Ceramic Construction: Flame-retardant tube with sand filling enhances safety and arc suppression.
• Easy Installation: Standard 1/4″ x 1-1/4″ (5x20mm) dimensions for seamless compatibility with fuse holders/clips.
• Certified Safety: UL/CSA certified for compliance with North American standards.
