Airpax LMLK1-1RLS4-30319-80 Low Voltage Circuit Breaker

Airpax LMLK1-1RLS4-30319-80 is a bolt-in, single-pole low-voltage circuit breaker engineered for DC protection in compact power paths. It is specified for 80 A and 80 V (DC), with a short-circuit interrupt rating of 10 kA to help protect feeders and control circuits in tight enclosures. The unit uses bolt-in terminals described as small studs with three pins and features a black handle for immediate visual indication of on/off status. The RLS4 suffix indicates an alarm auxiliary switch option, providing remote trip indication and enabling integration with monitoring or annunciation systems. As part of Airpax’s LMLK family, the 30319-80 variant is frequently cataloged by distributors under the same code, reflecting its role as a space-efficient, bolt-in protection device for DC applications in industrial panels and equipment racks. Airpax is a brand now associated with Sensata Technologies, and LMLK-style breakers are commonly referenced in supplier catalogs and spare-parts inventories for DC protection needs where compact form factor and dependable interruption performance are required.
