The 412-K14-LN2-20A is a single-pole, high-performance thermal circuit breaker with a 20A current rating, specifically designed for aircraft applications. This model features a black finish, M4 screw terminals (K14), and a threadneck panel mount design. It provides reliable overcurrent protection with a tease-free, trip-free, snap-action mechanism and push/pull on/off manual actuation, while an indicator band clearly shows the tripped/off position. Engineered for DC 28V systems, it operates reliably across a wide ambient temperature range of -55°C to +75°C. This circuit breaker is ideal for protecting extra low voltage wiring systems in aircraft, defense equipment, and other demanding environments.
