Applications
The Airpax 205 series is a line of magnetic hydraulic circuit breakers widely used in industrial equipment, military and aerospace systems, marine applications, and commercial electronics where reliable panel-mount branch-circuit protection is needed. The DC rating and auxiliary switch make this style of breaker common in telecom power systems, uninterruptible power supply (UPS) cabinets, DC-powered equipment racks, and custom control panels. The auxiliary switch contact allows the breaker's trip or on/off state to be monitored remotely or used to interlock other circuits — a feature frequently required in automated systems and equipment that must signal a fault condition to a controller or alarm. Airpax (now a Sensata Technologies brand) has produced this 205 series for decades, and these breakers remain in active use in both original equipment and maintenance/replacement applications across industrial and defense sectors.
