   - Motors 

- LPN-RK-(amp)SP (non-indicating) 

- LPN-RK-(amp)SPI (indicating) 

## **Description:** 

Ultimate protection Class RK1 dual element, current-limiting, time-delay fuses available with optional open fuse indication. 

## **Specifications:** 

## **Ratings** 

- Volts 250Vac/dc* 

- Amps 70-600 A 

- IR 

- 300kA Vac RMS Sym. 

- 100kA Vdc 

- Indicating versions not Vdc rated. 

## **Agency information** 

- cULus Listed file No. JDDZ.E4273 

- UL 248-12 – Class RK1 Fuses 

- CSA C22.2 No. 248.12 – Class RK1 Fuses 

- CE 

- Solenoids 

- General purpose circuits 

## **Features and benefits** 

- Industry’s only UL Listed and CSA Certified fuse with a 300 kA interrupting rating that allows for simple, worry-free installation in virtually any application. 

- Fast short-circuit protection and dual-element, time-delay performance provide ultimate protection. 

- Reduces existing fuse inventory by up to 33% when upgrading to Low-Peak fuses. 

- Consistent 2:1 ampacity ratios for all Low-Peak fuses make selective coordination easy. 

- Time-delay permits 130% FLA sizing for back-up motor protection. 

- Current-limitation protects downstream components against damaging thermal and magnetic effects of short-circuit currents. 

- Protects against single-phase motor damage. 

- Proper sizing can provide “no damage” Type 2 coordinated protection for NEMA and IEC motor controllers.
