Bussmann MDA-1-R Time Delay Fuse

Reliable Overcurrent Protection for Demanding Applications

Engineered for precision and durability, the Bussmann MDA-1-R is a time-delay fuse designed to protect sensitive electrical circuits from overloads and short circuits. Part of Eaton’s Bussmann series—a benchmark in circuit protection—this fuse combines delayed response to temporary inrush currents with rapid interruption of sustained faults, minimizing downtime and equipment damage.

Key Features

  • Time-Delay Design: Withstands initial surges (e.g., motor startups or transformer energization) without nuisance blowing, while responding decisively to prolonged overcurrents.
  • Rejection Feature (R-Suffix): Patented design prevents accidental installation of incorrect fuse types, enhancing safety and compliance.
  • 1 Amp Rating: Optimized for low-current circuits in industrial controls, HVAC systems, and automation panels.
  • Durable Construction: Ceramic body and precision-calibrated element ensure stable performance in temperatures up to 85°C (185°F).
  • Standards Compliance: Meets UL/CSA 248-14 standards for branch circuit protection.

Typical Applications

  • Motor control centers
  • Power supplies and transformers
  • Industrial machinery and PLCs
  • Lighting systems and HVAC units
