Specification: Colour: Black Current: 20A /30A/ 40A /50A /60A /80A /100A /125A/ 150A Features: Insurance can be restored, or power can be manually cut off Application: 12V-24V such as cars/boats Material: ABS, gold-plated interface Size: about 100*42*42mm quantity: 1feature: 1. High sensitivity, which can protect electrical appliances from the influence of the circuit in time 2. After disconnecting and troubleshooting, you can manually restart and use it manually 3. Can control large current circuitsWay of working: 1. Circuit breaking protection: When the current reaches the cut-off value, the long handle automatically bounces and cuts off the power supply. Generally, it trips in a short-circuit condition. After the fault is eliminated, pre the long handle back to the position to form a path. 2. Manually cut off the power: We need to disconnect the circuit when refitting, and directly pre the oval red button on the insurance. At this time, the long handle automatically pops up to cut off the power. Connect as above, and then pre the long handle back to its position.Instructions: 1. Wiring 2. Pre the oval button, the long handle pops open, and the circuit breaker is cut off. (Be sure to pre the elliptical button, if the power is cut off by the long handle directly, the circuit breaker will be broken). 3. After resetting the ejected long handle, the circuit breaker is energized.
