Cooper Bussmann FRN-R-200 Cartridge Fuse 200A 250V

Product Description

The COOPER BUSSMANN FRN-R-200 is a 200-amp, 250-volt Type FRN-R cartridge fuse featuring Fusetron dual-element time delay technology. It is designed to carry temporary motor inrush currents without nuisance opening while still providing reliable short-circuit and overload protection. Licensed electricians and industrial maintenance technicians install this fuse in fusible disconnect switches, motor control centers, and branch circuit panels where Class RK5 time delay protection is required. At 7.13 inches long and 1.56 inches in diameter, it fits standard Class R fuse holders and rejection-style disconnect switches.

This fuse is suited for residential, commercial, and light industrial applications where motor loads, HVAC equipment, pumps, and compressors demand time delay protection. The dual-element construction tolerates the high starting currents typical of single-phase and three-phase induction motors without sacrificing downstream overcurrent protection. It is commonly installed in fusible safety switches, panelboards, and combination motor starters serving loads up to 200 amps at 250 volts AC or DC.

Compatibility

Designed as an OEM-style replacement for Class RK5 Type FRN-R cartridge fuse applications in 250-volt fusible disconnect switches, motor control centers, and branch circuit overcurrent protection equipment.

Installation Notes

Installation must be performed by a qualified electrician in accordance with the National Electrical Code (NEC) and all applicable local codes. Always de-energize and lockout/tagout the disconnect or panel before removing or installing fuses. Verify the replacement fuse rating matches the circuit and load requirements before restoring power. Do not substitute a non-time-delay fuse in applications specifying Type FRN-R time delay protection.
