The NOARK B1E1D40 thermomagnetic miniature circuit breaker is a 40 A device rated for 277 VAC and 125 VDC, providing compact overcurrent protection for mixed-voltage circuits. Its thermomagnetic design combines thermal and magnetic trip mechanisms to respond to overloads and short circuits, helping safeguard wiring and equipment. Ideal for protecting branch circuits in electrical panels and control applications where dual voltage operation is required.
