Bussmann MDL-2-1/4-R Time Delay Fuse

Overview

The Bussmann MDL-2-1/4-R is a premium time-delay fuse designed for reliable circuit protection in demanding electrical systems. Engineered to withstand temporary current surges while responding decisively to persistent overloads, this fuse prevents damage to sensitive equipment and minimizes downtime. Its compact, rejection-style design ensures compatibility with standard automotive, industrial, and appliance applications.

Key Features

• Time-Delay Performance: Safely absorbs short-duration overloads (e.g., motor startups) without nuisance blowing, while interrupting sustained overcurrents within seconds.
• Rejection Feature (R-Type): Patented “rejection” slot prevents accidental installation of lower-rated fuses, enhancing safety compliance.
• Durable Construction: Precision-engineered with a ceramic body and sand-filled element for stable arc suppression and consistent performance.
• Standard Dimensions: 2-1/4″ (60mm) length fits common Class CC fuse holders and panels.
• Voltage Rating: 600V AC/DC for versatile use across multiple systems.
• Current Rating: Factory-calibrated for optimal protection (specific amperage variant selected upon purchase).

Applications

• HVAC compressors and blower motors
• Industrial control panels and transformers
• Power supplies and appliance circuits
• Automotive auxiliary systems
• Pump and conveyor motor protection
