Bussmann MDQ-3 Time Delay Fuse

Engineered for Reliable Circuit Protection

The Bussmann MDQ-3 Time Delay Fuse delivers robust overcurrent protection for electrical systems requiring tolerance to temporary inrush currents. Designed for industrial and commercial applications, this fuse safeguards equipment like motors, transformers, and solenoids from damaging overloads and short circuits while accommodating startup surges.

🔑 Key Features:

• Time-Delay Design: Withstands momentary current spikes (e.g., motor startups) without nuisance tripping.
• Dual-Element Construction: Combines short-circuit protection with thermal overload response for sustained faults.
• High Interrupting Rating: Safely interrupts high fault currents to prevent equipment damage.
• Compact Size: Space-efficient MDQ series footprint simplifies panel integration.
• UL/CSA Certified: Meets North American safety standards for reliability.

⚙️ Typical Applications:

• Motor control centers (MCCs)
• HVAC systems and compressors
• Transformers and power supplies
• Industrial machinery and pumps
• Capacitor banks and lighting circuits

📌 Specifications:

• Type: Dual-element, time-delay fuse
• Voltage Rating: 600V AC
• Ampere Range: Varies by model (check datasheet)
• Interrupt Rating: 200kA
• Approvals: UL 248-10, CSA C22.2

Ideal for installations where electrical loads experience frequent startups, the MDQ-3 minimizes downtime and extends equipment lifespan. Always verify compatibility with local codes and system requirements.
