LKE circuit breakers are compactly designed products capable of higher performance ratings and greater reliability. These circuit breakers have ratings of up to 50kA for breaking capacity and 2000A for rated current (without fan-cooling) . The circuit breakers have incorporated the latest concepts in circuit breaker design, including encapsulated pole-assemblies, permanent-magnet actuator drives, spring-mechanism with low part-count and system integration with rogowski-coil current censors and self-powered relays.
