Features:
High Ampere thermal trip circuit breaker with manual reset switch,
suitable for other  electrical systems. Ideal for use in harsh environments such as racing cars to provide protection against current overload or short circuits.
Protective rubber cap prevents unnecessary short circuits.
Commonly used in truck, bus, RV and marine applications;
also used for battery cost and  audio systems.
Switchable surface mount circuit breakers are commonly found in
auxiliary and accessory circuits for truck, bus, camper- and marine systems.
Sealed waterproof unit for engine compartment and bilge areas.
The trip switch manual can quickly disconnect the circuit in an emergency.
Connecting bolt size-M6 x 2 nut with integral locking ring to prevent

How to use: Working method:
1. Open circuit protection: When the current reaches the disconnection value,
the long handle automatically pops open and cuts off the power.
Generally, the short-circuit situation jumps off.
After the fault is removed, press the long handle back to the original.
Bit can form a pathway.
2. Manual power off: We need to disconnect the circuit during the modification,
and directly press the oval red button on the fuse.
At this time, the long handle automatically pops open to cut off the power.
Connect it as above, then press the long handle back to the original position.
