Bussmann FRS-R-200 200A 600VAC Class RK5 Time-Delay Fuse

The Bussmann FRS-R-200 is a new, genuine Eaton Bussmann Fusetron series dual-element, time-delay, current-limiting fuse rated 200 amperes at 600V AC and 300V DC, classified as UL Class RK5 with an interrupting rating of 200kA AC and 20kA DC. The dual-element design incorporates a separate overload element and short-circuit element in a single fuse body, providing motor-circuit-appropriate time delay that rides through normal inrush currents (up to 500% FLA for up to 10 seconds) while still providing fast response to sustained overloads and short circuits. The fuse features copper blade-style (knife-blade) terminals with rejection notches on one end that enforce Class RK5 selectivity, preventing installation in Class K5 or H fuseholders and ensuring coordinated protection in properly specified panels and motor control centers. The cylindrical steel body with copper blades measures approximately 9-9/16 inches in overall length and is manufactured by Cooper Bussmann LLC in Mexico; the label carries UL listing, Type D designation, and UPC 051712508483. This fuse is suitable for motor branch-circuit protection, service entrance equipment, panelboards, and industrial control panels where time-delay protection is required per NEC Article 430.
