The 412-K14-LN2-7.5A is a single-pole high-performance thermal circuit breaker designed for aircraft applications with tease-free, trip-free snap-action mechanism and push/pull on/off manual actuation conforming to EN 60934 (M-type TO CBE). It features screw terminals M4 to aircraft specifications, black finish, and an indicator band on the push button that clearly shows the tripped/off position. The breaker is rated for DC 28 V with a current rating of 7.5 A and typical voltage drop of =300 mV, offering an interrupting capacity of 6,000 A and insulation resistance greater than 100 MO. It operates reliably across an ambient temperature range of -55°C to +75°C and is qualified to UL 1077 and CSA C22.2 No 235 standards. This breaker is ideal for extra low voltage wiring systems on aircraft and other vehicles, defence equipment, and battery-powered machines where reliable overcurrent protection and long operational life are essential.
