Bussmann MDQ-15 Time Delay Fuse

Bussmann MDQ-15 Time Delay Fuse

Robust Circuit Protection for Demanding Applications

Engineered for reliability, the Bussmann MDQ-15 is a high-performance time-delay fuse designed to safeguard electrical systems from damaging overcurrents. Its slow-blow characteristic makes it ideal for circuits with temporary inrush currents, preventing nuisance tripping during motor startups, transformer energization, or capacitive loads.

Key Features

• Time-Delay Design: Tolerates short-term surges (up to 10x rated current) without interruption, while providing reliable protection against sustained overloads and short circuits.
• Optimal Compatibility: Rated for 15A at 600V AC/DC, suitable for industrial controls, HVAC systems, power supplies, and appliance circuits.
• Durable Construction: Features a ceramic body for superior thermal stability, sand-filled arc quenching for rapid fault interruption, and nickel-plated brass end caps for corrosion resistance.
• Safety-Certified: UL/CSA approved, meeting strict standards for performance and reliability in North American markets.
• Easy Replacement: Standard 1/4″ x 1-1/4″ (6.3x32mm) dimensions ensure drop-in compatibility with existing fuse holders.

Applications

• Motor control centers
• Transformers and solenoids
• PLCs and industrial machinery
• Power conversion equipment
• Lighting ballasts and HVAC compressors
