Airpax JLM-1-1RLS5-33857-200A Circuit Breaker

Airpax Sensata Technologies JLM-1-1RLS5-33857-200A is a 1P magnetic-hydraulic delay circuit breaker rated for 200 A at 65 V, built to protect electrical circuits in low-voltage power distribution and control-panel installations. The unit integrates a hydraulic delay mechanism to reduce nuisance trips on brief inrush currents while still delivering fast protection during sustained faults, and it carries an interrupting capacity of 25 kA. A lever-operated actuator provides straightforward manual control, and this specific package includes an auxiliary MBKR1102-200A accessory for additional monitoring or signaling within a protection scheme. As part of the JLM-1 family from Airpax (Sensata), this breaker is designed for rugged protection in industrial environments where reliable single-pole protection at relatively high current is required. Typical applications include control circuits and feeders in equipment racks and panels where a durable, high-current protective device is essential, and where the 65 V rating defines the maximum voltage it is intended to interrupt. This model’s combination of 200 A capacity, 65 V rating, 25 kA interrupting capability, and hydraulic delay makes it suitable for protecting heavy-load circuits while minimizing disruption from transient surges, with the added benefit of a dedicated auxiliary contact for enhanced integration into broader protection systems.
