Airpax LELK1-1RS4-30452-20 1 Pole Circuit Breaker

Airpax LELK1-1RS4-30452-20 is a 1‑pole hydraulic-magnetic circuit breaker rated for 20 A and up to 80 VDC, built for panel-mount installation with stud terminations. The 1RS4 variant denotes an integrated alarm switch for monitoring and a lever actuator for manual operation, with a non-illuminated indicator and RoHS-compliant construction. Dimensions are approximately 63.25 mm in length, 47.22 mm in width, and 19.05 mm in height, with a unit weight around 90 g, and termination is via studs suitable for panel mounting. The unit uses a magnetic (hydraulic delay) trip mechanism and includes an integrated alarm switch for monitoring the breaker status, with a -40 to +85 C operating range. RoHS compliance and compact dimensions help integrate this breaker into constrained enclosures, while the 1-pole design simplifies wiring in simple DC protection circuits. As part of the LELK1-1RS4 family, the 30452-20 model aligns with Airpax's line of hydraulic-magnetic breakers featuring alarm options for equipment monitoring.
