M55629/7-092 is a single-pole magnetic circuit breaker designed for low-power unsealed applications with trip-free and series trip functionality. This breaker is rated for 15.0 amperes at 50 V dc with tripping time delay type A, featuring a maximum resistance of 0.01 ohms. The device operates across a temperature range of -40°C to +85°C and is designed to interrupt faults at 2,000 amperes at 50 V dc and 1,000 amperes at 240 V ac (60 and 400 Hz). It features a white toggle lever actuator with 4 pounds maximum operating force and 25 pounds actuator strength, along with screw terminals rated for 30 pounds applied load and 10 inch-pounds applied torque. This breaker is commonly used in military and aerospace applications where reliable overcurrent protection and trip-free operation are essential for circuit protection in low-power systems.
