- Trip‑free operation; cannot be reset into a fault
- Resettable overload capacity up to 10× rated current
- #6‑32 or #8‑32 screw terminals and a 3/8‑24 threaded mounting bushing (series dependent)
- Rated for 50 VDC or 250 VAC (to 400 Hz)
- Interrupting capacity: up to 2,000 A @ 50 VDC on most models
- Designed for aviation use; widely accepted across general aviation platforms
Electrical Performance (@ +25 °C)
- Carries 100% of rated current; may trip 101–134%; must trip at 135% within 1 hour
- Dielectric strength: >1,500 V RMS
- Endurance: >6,000 cycles at 100% load or 10,000 mechanical cycles
