Airpax LMLK1-1REC4-52-40 0-T-01 Circuit Breaker

Airpax LMLK1-1REC4-52-40-0-T-01 is a hydraulic-magnetic, single-pole circuit breaker from Airpax (Sensata Technologies) in the LMLK1-1REC4 family. This panel-mount device uses stud termination and a manual handle actuator for resettable protection, delivering dependable overcurrent interruption in a compact form. It is rated for 40 A continuous current and up to 80 V operation, with a 10 kA interrupting capacity to quickly break the circuit if a fault occurs. The unit operates as a non-illuminated switch in typical control-panel environments, providing clear physical indication of a trip through its lever action. The LMLK1-1REC4 family is designed for robust protection in industrial equipment and DC power feeds where space is limited and reliable disconnection is required. This particular configuration, denoted by the 52-40-0-T-01 suffix, reflects Airpax’s standardized form factor and terminal arrangement for a 1-pole, 40 A, 80 V hydraulic-magnetic breaker. When integrating into a system, verify that the stud termination and panel-mount dimensions align with your enclosure and that the 10 kA interrupt rating meets the fault-current requirements of your circuit.
