LS ELECTRIC Introduces High-Capacity Breaker to Support Airport Electrification and eGSE Charging

LS ELECTRIC America introduced the Susol UL Air Circuit Breaker, a high-capacity power protection system designed to support demanding electrical environments such as airport facilities, maintenance hangars, and electric ground support equipment charging networks. The company said the new breaker combines compact design with advanced monitoring capabilities to help operators manage growing power loads safely and efficiently.

As airports expand electrification programs and add high-output chargers for eGSE, the need for reliable low-voltage distribution has increased. The Susol UL ACB is rated up to 6000A with short-circuit capability up to 130kA at 508 Vac, providing protection for critical infrastructure that must withstand severe fault conditions. An integrated intelligent trip relay delivers real-time measurement, diagnostics, and communication functions, allowing maintenance teams to track performance and move toward predictive maintenance rather than reactive repairs.

LS ELECTRIC emphasized the modular design of the breaker, which reduces panel footprint and simplifies installation in space-constrained electrical rooms common at terminals and cargo facilities. Interchangeable trip units and rating plugs allow operators to adapt to changing load requirements, such as the addition of fast chargers or new automated baggage systems, without replacing major components. The unit maintains full N-phase current conduction capacity and is certified to UL 1066 and ANSI C37 standards for North American installations.

The breaker is manufactured at the company’s Bastrop, Texas facility, supporting domestic supply for OEMs, panel builders, and airport engineering teams. LS ELECTRIC said the product is aimed at organizations seeking to modernize power distribution for electrified ramp operations, large maintenance complexes, and other high-demand aviation applications where uptime and electrical safety are critical.
