Airpax Electronics LEL11-31965-3-V Circuit Breaker

Airpax Electronics LEL11-31965-3-V is a compact two‑pole hydraulic‑magnetic circuit breaker designed to interrupt fault currents in AC power circuits, delivering a 20 A nominal current rating in a rugged, space‑efficient package suitable for panel mounting in small equipment enclosures such as power supplies, control panels, and compact instrumentation racks. Rated for up to 250 VAC with 50/60 Hz operation, the LEL11-31965-3-V uses a hydraulic‑magnetic mechanism that combines a fast magnetic trip with a controlled hydraulic delay to produce a precise trip curve, helping to minimize nuisance trips during brief surges while maintaining quick response to actual faults. This device is part of the Sensata Airpax line, a heritage of rugged overcurrent protection for power electronics, control panels, power adapters, and other equipment where reliable protection in a compact form factor is required, aided by proven endurance in industrial and laboratory environments. Typical installations include input protection for power supplies, motor controllers, and small electronic assemblies in both commercial and industrial settings that require 20 A, two‑pole protection at 50/60 Hz, aligning with common electrical standards for distributed power systems.
