A manual reset circuit breaker protects your electrical system from overloads and short circuits. When tripped, it cuts off power to prevent damage, and can be manually reset once the issue is investigated and resolved - making it ideal for automotive, marine, solar, and off-grid applications.

A manual reset breaker stays off after tripping, allowing you to inspect and correct the fault before restoring power. In contrast, an automatic reset breaker reconnects power automatically once it cools down, which can risk repeated faults if the issue isn't fixed.

Alvolta manual reset circuit breakers are IP67 rated, meaning they are internally sealed for protection against moisture, dust, and dirt. They are also ignition protected.

Circuit breakers will experience less voltage drop across the circuit. When they are tripped, you can simply reset the device as opposed to having to source and install a new fuse, should a fuse blow. These units offer lower voltage drop than a fuse and can be used as an occasional isolation switch.

These breakers are designed for flush mounting on a surface. Simply mount the breaker to the surface with M8 bolts and connect your positive circuit wires to the terminals as directed. Always ensure the breaker's rating matches your circuit's current load.
