Cooper Bussmann FRS-R-110 Fusetron Dual Element Class RK5 Time Delay Fuse

Cooper Bussmann FRS-R-110 Fusetron Dual Element Class RK5 Time Delay Fuse

The Cooper Bussmann FRS-R-110 Fusetron fuse is a dual-element, time-delay fuse designed to provide advanced protection for various electrical applications. With a current rating of 110 amperes and voltage ratings of 600 VAC and 300 VDC, this Class RK5 fuse ensures reliable performance in demanding environments.

Key Features

• Dual-Element Construction: Offers both overload and short-circuit protection, allowing for closer sizing to motor full-load amperes (FLA) and enhanced system safety.
• Time-Delay Capability: Provides a minimum of 10 seconds delay at 500% of rated current, accommodating temporary inrush currents without nuisance openings.
• High Interrupting Rating: Capable of interrupting up to 200,000 amperes at 600 VAC, ensuring robust protection against high fault currents.
• Current-Limiting Design: Reduces the let-through energy during fault conditions, minimizing potential damage to downstream equipment.
• Rejection-Type Feature: Prevents the installation of fuses with lower interrupting ratings, maintaining system integrity and safety.
