Circuit protection: high amp thermal trip circuit breakers with a manual reset switch that can be used on auxiliary DC electrical systems. The recoverable fuse automatically disconnects and protects the circuit when the current reaches a predetermined value. Specification: Material: plastic + metal Color: black shell + gray cover Rated current: 200A Package List: 1 * Circuit Breaker Working Way: 1. Open circuit protection: when the current reaches the disconnection value, the long handle automatically opens for power supply. Generally, the short circuit is tripped. Once the fault has been eliminated, press the long handle to return it to its original position. to form a path. 2. Manual power off: We need to disconnect the circuit when reassembling, and press the insurance red oval button directly. At this time, the long handle will automatically open and run power. Connect the same as above, then press the long handle back to the original position.
