Airpax JLM-1-1-53-1-B4-200 Circuit Breaker Magnetic Hydraulic Delay

The Airpax/Sensata JLM-1-1-53-1-B4-200 is a hydraulic-magnetic circuit breaker designed for DC protection. With a 200 A current rating and a 65 V DC rating, this lever-actuated, panel-mount device employs a magnetic-hydraulic delay mechanism to provide a time-delayed response to overloads, fast magnetic tripping for clear faults and a damped delay to reduce nuisance trips from short surges. As part of the JLM family, it combines robust overcurrent protection with a compact form factor suitable for industrial control panels and equipment enclosures. Its panel-mount design and manual reset capability enable straightforward integration alongside other Sensata-Airpax protection devices, making it a reliable choice for protecting DC feeders and power modules in electrical assemblies where dependable, field-serviceable protection is required.
