Bussmann MDL-3-R Time Delay Fuse

Reliable Circuit Protection for Demanding Applications

Engineered for superior performance, the Bussmann MDL-3-R time-delay fuse delivers robust overcurrent protection in industrial and commercial electrical systems. This rejection-style fuse combines high interrupting capacity with a delayed response to prevent nuisance tripping during temporary surges, making it ideal for safeguarding motors, transformers, and inductive loads.

Key Features

• Time-Delay Design: Tolerates inrush currents (e.g., motor startups) without blowing, while responding swiftly to sustained overloads and short circuits.
• Rejection Feature (“-R” Model): Physically prevents installation in incompatible fuseholders, ensuring safe replacement and compliance with NEC guidelines.
• High Interrupt Rating: 200kA interrupting capacity for reliable protection against severe fault currents.
• Durable Construction: Ceramic body with precision-engineered elements for stable performance and longevity.
• Standard Sizes: Compatible with 250V AC systems; available in common ampere ratings for broad applicability.

Typical Applications

• Motor control centers (MCCs)
• HVAC systems
• Industrial machinery
• Power distribution panels
• Transformers and capacitors

Specifications

• Voltage Rating: 250V AC
• Interrupt Rating: 200,000A
• UL/CSA Listed: Meets industry safety standards
• Standards Compliance: NEC 240.60(D) rejection requirements

Choose the Bussmann MDL-3-R to enhance system uptime, reduce maintenance costs, and ensure code-compliant circuit protection.
Always verify ampere rating and voltage compatibility prior to installation.

*Note: Amp rating (e.g., 1A–30A) must be selected based on specific circuit requirements; consult datasheet for details.*
