BUSSMANN FRN-R-12 Fuse, 12 A, Dual, Non Indicating, Standard, 250 V

Bussmann FRN-R-12 Fusetron fuse is utilised in electrical systems to protect circuits and equipment from overcurrents or short circuits. It is designed for applications where a 12A current threshold is required.

Working Mechanism:

• When the current flowing through a circuit exceeds its rated capacity, the fuse's dual-element design responds. One element is responsible for handling small & temporary overloads, while the other addresses larger overcurrents and short circuits.
• In the event of an overload or short circuit, the heat generated by the excessive current causes the fuse's smaller element to melt first, creating an intentional delay. This delay allows for momentary surges, like those encountered during motor startups, without triggering an unnecessary outage. If the overload persists and becomes more severe, the larger element of the fuse melts, swiftly breaking the circuit and preventing damage to equipment and wiring.

Features:

• Bussmann FRN-R-12 fuse features fibreglass construction for durability and corrosion resistance.
• It is equipped with a dual-element, offering time delay to handle temporary overloads.
• This FRN-R-12 service fuse has 200kA at 250VAC and 20kA at 125VDC interupting capacities to swiftly break the circuit during faults.
• It has a nonindicating design, streamlining installation to eliminate the need for additional indicators, while maintaining its protective functionality.
• This 12A Fusetron fuse offers a time delay function, denoted by its RK5 classification, effectively managing temporary overloads without unnecessary tripping.

Compatible Accessories:

• Bussmann RM25030-1CR Fuse Block: This fuse box is designed to work seamlessly with the fuse, providing a secure and efficient connection for enhanced electrical safety and protection.
