Bussmann MDQ-5 Time Delay Fuse

Engineered for Robust Overcurrent Protection

Overview

The Bussmann MDQ-5 is a high-performance time-delay fuse designed for applications requiring tolerance to temporary inrush currents. With its dual-element design, it provides reliable circuit protection for inductive loads, motors, and transformers while preventing nuisance tripping during startup surges.

Key Features

  • Dual-Element Technology: Combines thermal and magnetic protection for delayed response to momentary overloads (e.g., motor startup) and rapid interruption of sustained faults.
  • Time-Delay Function: Allows brief overcurrents (up to 500% of rated current) without blowing, minimizing operational disruptions.
  • Rated Specifications:
    • Current Rating: 5 Amps
    • Voltage Rating: 250V AC
    • Interrupting Rating: 10,000 A
  • Compact Design: Standard 1″ × 1/4″ (13.3 × 6.3 mm) dimensions for easy integration into fuse blocks, panels, and OEM equipment.
  • Compliance: UL 248-14 Listed, CSA certified, and RoHS compliant.

Applications

Ideal for:

  • Motor control circuits (single-phase/three-phase)
  • Transformers, solenoids, and ballasts
  • HVAC systems, pumps, and industrial machinery
  • Power supplies with capacitive loads

Benefits

  • Enhanced Durability: Silver-plated copper ends ensure low resistance and reliable connections.
  • Safety-First Protection: Prevents equipment damage from short circuits and overloads while maintaining system integrity.
  • Versatility: Compatible with standard MD series fuse holders (e.g., MDL, MDK).

Why Choose MDQ-5?

Trusted by engineers for over 50 years, Bussmann’s MDQ series fuses deliver industry-leading reliability. The MDQ-5 offers optimized protection where sustained operation under transient loads is critical—backed by Eaton’s global engineering excellence.
