The LPSRK400SP current-limiting time-delay fuse from Schneider Electric is built for robust performance and safety in electrical systems. It is classified under the RK1 series of fuses, providing reliable operation with a rated current of 400 Amperes. The fuse's primary strength lies in its ability to handle both AC and DC applications, accommodating voltage ratings of 600 V for AC and 300 V for DC circuits.
Manufactured with fiberglass-reinforced plastic for its housing and copper alloy for its conductors, the LPSRK400SP ensures a strong and resilient design. The peak let-through current capability minimizes stress during short-circuit situations, enhancing longevity and reliability in various applications. The blade-type contact terminals facilitate efficient connections, allowing for flexible installation in either horizontal or vertical orientations.
The fuse is designed with a time-delay (slow-blow) function that allows it to tolerate brief overloads without interruption, making it suitable for applications that experience inrush currents. It can withstand melting I²t clearing values of up to 95,000 A²s, which is crucial in managing energy demands while ensuring safety against faults. With an interrupting capacity of 200 kA for AC and 100 kA for DC circuits, the LPSRK400SP is a dependable solution for current-limiting scenarios in industrial and commercial electrical systems.
