Bussmann MDA-1-1/2-R Time Delay Fuse

Overview

The Bussmann MDA-1-1/2-R is a premium time-delay fuse designed for reliable circuit protection in demanding electrical applications. Engineered for 1.5A (1-1/2 ampere) current ratings, this fuse combines precise overload response with robust durability. Its time-delay characteristic allows temporary inrush currents during motor starts or transformer energization while safeguarding against prolonged overcurrents and short circuits.

Key Features

• Current Rating: 1.5 ampere (1-1/2 A)
• Time-Delay Design: Withstands initial surge currents (5-10x rated current) without nuisance tripping
• Voltage Rating: Compatible with 250V AC/DC systems (verify local specifications)
• Interrupting Rating: High interrupting capacity (typically 200kA) for superior fault protection
• Construction: Ceramic body with sand filler for arc suppression and stable performance
• Terminals: Brass end caps ensure low-resistance connections
• Compliance: Meets UL/CSA standards for safety and reliability

Applications

Ideal for protecting:
✅ Motor circuits (single-phase and three-phase)
✅ Transformers and solenoids
✅ HVAC systems and compressors
✅ Industrial control panels
✅ Lighting ballasts and power supplies

Benefits

• Enhanced Equipment Lifespan: Prevents damage from sustained overloads
• Reduced Downtime: Eliminates false trips during legitimate startup surges
• Universal Compatibility: Class CC fuse dimensions (1/4″ x 1-1/4″) for easy retrofitting
• Trusted Brand: Backed by Eaton’s Bussmann legacy of industrial-grade circuit protection

Note: Always confirm voltage ratings and local electrical codes before installation. Replace only with identical specifications to maintain system integrity.
