Installation:
Surface mount on panel or firewall, easy to use and durable, protective stud insulators included.
Way of working:
(1)Circuit break 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, press the long handle back to the original position to form a path.
(2) Manually cut off the power: We need to disconnect the circuit when refitting, and directly press the oval yellow button on the insurance. At this time, the long handle automatically pops up to cut off the power. Connect as above, and then press the long handle back to its original position.
(3)No need to replace the fuses, the system can be reset by a simple switch which also offers safe and instant system shut down.
Kindly Note:
1. Do not use as a switch where high inrush currents are expected
2. Do not push back reset lever before troubleshooting
3. Please allow 1-3cm differs due to manual measurement
