Bussmann MDA-8-R Time Delay Fuse

Bussmann MDA-8-R Time Delay Fuse

Precision Protection for Demanding Circuits

The Bussmann MDA-8-R is a high-performance time-delay fuse designed to safeguard electrical circuits from overcurrents while accommodating temporary inrush currents. Engineered by Eaton’s Bussmann division, this 8-amp cartridge fuse combines reliable circuit protection with durable construction, making it ideal for industrial, commercial, and residential applications where equipment startup surges are common.

Key Features

• Time-Delay Design: Tolerates momentary overloads (e.g., motor startup surges) without nuisance tripping, while responding instantly to sustained faults or short circuits.
• Rated Specifications: 8A current rating, 250V AC voltage rating, and a high interrupting capacity (200 kA) for superior safety in fault conditions.
• Compact & Durable: Standard 1/4″ x 1-1/4″ (5x32mm) ceramic body with robust end caps for vibration resistance and long service life.
• Easy Installation: Drop-in replacement for standard Class CC fuses, compatible with UL/CSA-recognized fuse holders.
• Safety Certified: Meets UL 248-10 and CSA C22.2 standards for reliable performance and compliance.

Typical Applications

• Motor control circuits (single-phase and three-phase)
• Transformers, solenoids, and HVAC systems
• Power supplies with capacitive loads
• Industrial machinery with high inrush currents
• Lighting and appliance panels

Why Choose the MDA-8-R?

• Engineered Resilience: Withstands 500% overload for up to 10 seconds, preventing false trips during normal operations.
• Fail-Safe Protection: Sacrificial design ensures complete circuit disconnection during faults, protecting downstream components.
• Trusted Brand: Backed by Eaton’s Bussmann legacy of innovation in electrical safety solutions.

Note: Always verify compatibility with existing fuse holders and consult local electrical codes before installation. Replace only with identical amperage and voltage ratings.
