The Littelfuse KLPC700 is a 700 amp current‑limiting power fuse in Littelfuse’s KLPC family, engineered for high‑performance overcurrent protection in low‑voltage power distribution systems. The KLPC series is part of Littelfuse’s broad portfolio of industrial fuses designed to safeguard circuits in switchboards, distribution panels, motor control centers, and feeder applications. With a voltage rating typically up to 600 VAC, the KLPC700 is well suited for protecting large service entrances, feeders, and major branch circuits where both overload and short‑circuit conditions must be cleared safely and effectively.
Electrically, the KLPC700 is classified as a current‑limiting fuse, meaning that when it operates under fault conditions it limits the let‑through energy (I²t) that downstream components are exposed to. This helps reduce thermal and mechanical stress on conductors, switchgear, and connected equipment, improving system coordination and reducing damage during severe faults. The KLPC series carries high interrupting ratings, typically in excess of 200 kA RMS symmetrical at 600 VAC, ensuring the fuse can safely clear high available fault currents common in commercial and industrial power systems. These fuses are UL and CSA listed, meeting North American code and safety requirements for power fuses in service entrance and feeder protection roles.
The KLPC700 features robust construction with rugged terminals for secure connection in compatible KLPC fuse holders or blocks, and a body design that makes identification and replacement straightforward during maintenance. Littelfuse also offers a full complement of accessories and mounting hardware to support coordination with circuit breakers, switchgear, and protective systems in complex power distribution architectures. The KLPC family’s combination of current‑limiting performance, high interrupting capacity, and broad application flexibility makes the KLPC700 a strong choice for engineers, facility managers, and contractors who require dependable protection in large electrical systems.
