AIRPAX / SENSATA M3901903230S Magnetic Circuit Breaker

The AIRPAX / SENSATA M39019/03-230S is a robust magnetic circuit breaker designed for critical applications requiring reliable circuit protection. This low-power, sealed, trip-free two-pole breaker offers a voltage rating of up to 50V DC and a maximum current rating dependent on the dash number selected from Table I. It is suitable for use in military and industrial environments where shock and vibration resistance are important. The threaded inserts exceed the height of the bushing by .005 to .015 (0.13 mm to 0.38 mm).
