General Purpose Fuses
UL Power Fuses
Class RK1 - High Speed- HSRK
arrow bullet Back to UL Power Fuses

Protect your electrical power wiring and power semiconductors with a single fuse.

The new HIGH SPEED RK1 (HSRK) combines semiconductor fuse performance with NEC branch circuit compliance. The fuse was designed with two specific applications in mind:

To provide semiconductor fuse performance to solid state drive applications but in the larger RK body sizes that have been typically installed in older systems.
To provide industrial power applications with the most current limiting fuse available, which in turn provides the best arc flash mitigation available to power systems using the larger RK size fuses.

	Most current limiting RK1 available
	Provides the best Arc flash mitigation for feeder and branch circuits (non motor load circuits)
	Excellent cycling ability for frequent drive starts and stops without nuisance opening
	Extremely Low I2t

	Branch circuits
	AC drives
	Solid state controllers
	Feeder circuits
	Arc flash mitigation
