Bussmann MDA-20-R Time Delay Fuse

Overview

Engineered for reliable circuit protection, the Bussmann MDA-20-R is a 20-amp time-delay fuse designed to withstand temporary current surges while providing robust overcurrent protection for inductive loads. Ideal for motor-driven applications, this fuse prevents nuisance tripping during startup while safeguarding equipment against prolonged electrical faults.

Key Features

  • Time-Delay Performance: Tolerates initial inrush currents (e.g., motor startups) without unnecessary interruption, then trips during sustained overloads or short circuits.
  • High Interrupt Rating: 200,000 AIC (Amperes Interrupting Capacity) ensures reliable protection even under extreme fault conditions.
  • Voltage Rating: 250V AC for versatile compatibility with residential and light industrial systems.
  • Durable Construction: Sand-filled ceramic body suppresses arcs and enhances safety during operation.
  • Certified Compliance: UL Listed and CSA Certified for guaranteed adherence to North American safety standards.
  • Compact Size: 1″ x 0.25″ (10.3mm x 5mm) cartridge design saves space in fuse blocks and panels.

Applications

  • Motor protection (HVAC, refrigeration, power tools)
  • Transformers and solenoids
  • Lighting ballasts and inductive control circuits
  • Industrial machinery with high startup currents
