BUSSMANN LPS-RK-4-1 2SP

The BUSSMANN LPS-RK-4-1 2SP is a two-pole, low-peak, time-delay fuse assembly in the RK1 class that combines two dual-element fuses in a single cartridge body, rated at 4.5 A. Rated for up to 600 V AC and 300 V DC, it delivers high interrupting capability—typically 300 kA at 600 VAC and 100 kA at 300 VDC—making it suitable for protecting circuits in motor controls, power distribution panels, and industrial equipment against short circuits and load surges. As part of the Bussmann LPS-RK family, the 2SP version provides dual-element protection with time-delay characteristics that tolerate temporary inrush currents while safeguarding wiring and components, and it is commonly used in RK1-class protection schemes across commercial and industrial electrical installations.
