Bussmann FRS-R-45 45A (lot of 6)

Bussmann FRS-R-45 45A Time-Delay Fuses (Lot of 6)

The Bussmann FRS-R-45 is a 45-amp, dual-element, time-delay fuse designed to provide superior protection for motors and transformers. This lot includes six fuses, each engineered to deliver reliable performance in demanding electrical applications.

Key Features

• Dual-Element Design: Offers optimal time-delay performance, allowing for closer sizing and enhanced protection of motors and transformers.
• Time-Delay Capability: Provides a 10-second delay at 500% of the rated current, accommodating temporary inrush currents without compromising protection.
• High Interrupting Rating: Rated at 200 kAIC at 600 VAC and 20 kAIC at 250 VDC, ensuring robust performance in high-fault current scenarios.
• Current Limiting: Limits the let-through energy, reducing potential damage to downstream components during fault conditions.
• Versatile Application: Suitable for use in combination starters, motor control centers, machinery disconnects, and power panelboards.

These fuses are designed to protect motors from burnout due to overloads and single phasing when properly sized. Their dual-element construction allows them to handle temporary motor overloads and surge currents, providing both high-performance short-circuit and overload protection. Additionally, the time-delay feature permits the use of smaller fuse ratings compared to non-time-delay fuses, leading to potential cost savings by allowing the use of smaller switches and panels.

Invest in the Bussmann FRS-R-45 fuses to ensure reliable and efficient protection for your electrical systems.
