Description
This manual reset circuit breaker is designed to provide reliable protection for 12–48V DC electrical systems across 4WD, caravan, camping and marine applications. Featuring copper alloy stud terminals, it allows secure, low-resistance connections for a wide range of accessory and auxiliary power circuits.
The manual reset mechanism enables quick recovery after an overload or short circuit without the need to replace fuses. Once the fault is cleared, the breaker can be reset manually, making it well suited to touring and off-grid setups where serviceability and reliability are important.
An ignition-protected housing makes this breaker suitable for installation in engine bays, canopies, battery boxes and marine environments. It is commonly used to protect circuits such as fridges, lighting, compressors, USB power systems, DC-DC chargers and other auxiliary loads.
Available in 20A, 30A, 40A, 50A, 60A, 80A, 100A, 150A and 200A ratings, this breaker provides a practical and reusable alternative to traditional fuse-based protection.
