Low-Peak® time-delay fuses,KRP-C_SP Class L
Low Voltage, Branch Circuit Rated Fuses - Branch Circuit Rated Fuses
Low-Peak® time-delay fuses
KRP-C_SP Class L
Specifications
Decription:
Time-delay fuse n 4 seconds (minimum) at 500% rated amps.
Construction:
Glass melamine tube with silver-plated end bells and blades. High grade silica-sand filler to quench fuse arc. O-ring seals to maximize
pressure build-up during
current-limiting action and ensure filler retention.
pressure build-up during
current-limiting action and ensure filler retention.
Ratings:
Agency Information:
CE, UL Listed-Special Purpose (meets all performance requirements of UL Standard 248-10 for Class L fuses),Guide JFHR, File E56412, CSA Certified (200,000 air), Class 1422-02, File 53787, Class L per CSA C22.2, No. 248.10.
Features and Benefits:
@ Time delay of four seconds at five times rating allows closer sizing on large motor loads combined with Class L current limitation.
@ Selective coordination ratio of 2:1 (within Low-Peak fuse family) prevents electrical shutdowns from extending beyond the failed circuit.
@ Interrupting rating of 300,000A RMS symmetrical provides adequate ratings without obsolescence for all electrical
systems, big or small.
@ Quality construction, using high-grade materials, provides lower watts loss and operating temperatures with superior arc quenching during current-limiting action.
