FRS-R-30 TIME DELAY FUSE

Product Description

The FRS-R-30 Time Delay Fuse is a Class RK5, dual-element, current-limiting fuse designed for protecting motor circuits, transformers, and industrial power distribution systems where short overloads and high inrush currents are expected.

It belongs to the Eaton Bussmann FRS-R (Fusetron) series, widely used in industrial control panels and machinery protection.

Key Features

• Time-delay (slow-blow) fuse for handling motor starting currents
• Class RK5 rejection-type design for safe and secure mounting
• Dual-element construction for superior overload protection
• High interrupting capacity for industrial fault protection
• Current-limiting design reduces damage during short circuits
• Withstands temporary inrush currents without nuisance tripping
• Cylindrical ferrule-style body for standard fuse holders
• Reliable performance in heavy-duty electrical systems
• Suitable for industrial and commercial applications
• UL/CSA certified for safety compliance
