About this product
The LX-Series hydraulic-magnetic circuit breaker delivers a high-performance, space-saving design built for the confined layouts of datacom and telecom power distribution units and rack systems. Building on the L-Series platform, the LX-Series raises maximum interrupt capacity to 10,000 amps, meeting a higher performance standard for demanding data infrastructure applications.
Available in one to three poles with a choice of rocker or push-to-reset actuators (vertical or horizontal legend), the LX-Series offers flexible terminal and mounting options to fit a range of panel designs. All units are trip-free, tripping on overload even when the actuator is forcibly held in the ON position, with positive trip indication so operators can see breaker status at a glance.
