Description

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

Overview
The Bussmann MDL-1-1/4-R is a high-performance time-delay cartridge fuse designed for reliable circuit protection in demanding electrical applications. Engineered to withstand temporary inrush currents without nuisance tripping, this fuse offers robust defense against sustained overloads and short circuits. Ideal for industrial and commercial settings, it ensures operational continuity while safeguarding sensitive equipment.

Key Features

  • Time-Delay Design: Tolerates initial surge currents (e.g., motor startups or transformer energization) without blowing, while responding decisively to prolonged overloads.
  • Amperage Rating: Precisely rated for 1.25A (1-1/4 Amp) operation.
  • High Interrupting Capacity: Supports up to 200kA interrupting rating at 600V AC, making it suitable for high-fault environments.
  • Rejection Base (R-Type): Features a patented “rejection” design that prevents installation into incompatible fuseholders, enhancing safety compliance.
  • Durable Construction: Industrial-grade materials ensure longevity and consistent performance under extreme conditions.
  • Standard Dimensions: 1/4″ x 1-1/4″ cartridge form factor for easy replacement in compatible holders.

Applications

  • Motor control circuits
  • HVAC systems
  • Transformers and solenoids
  • Industrial machinery
  • Power distribution panels
