These bi-metallic single pole breakers weigh less than 2 oz. and are especially suitable for home-built aircraft. Used as original equipment in Beech, Cessna and Piper aircraft.  Maximum operating voltages: 32 VDC and 250 VAC (to 400 Hz).
This W31 Series is a combination single pole switch and circuit breaker.  An overload puts the switch into the off position.
