What this is and why you need it A 100A manualreset circuit breaker designed for 12V, 24V, and 48V lowvoltage systems. It protects equipment and batteries from overcurrent, overvoltage, residual current, and overcharge conditions, reducing the risk of damage and downtime in vehicles, boats, and other lowvoltage installations. Key benefits Reliable protection: Interrupts unsafe currents immediately when tripped to prevent component damage and battery failure. Easy recovery: Prominent yellow handle pops open on trip and resets instantly by pushing the handle down—no tools required. Durable construction: Built with resistant material for strong electrical conductivity and longterm performance under demanding conditions. Clear fit and compatibility: Works across 12–48V systems and suits common lowvoltage applications. Important specifications Rating: 100A manual reset Voltage compatibility: 12V, 24V, 48V Protections provided: overcurrent, overvoltage, residual current, overcharge Size: 78*56*60 mm Housing: black shell with yellow actuator Typical applications (practical use scenarios) Automotive: Protects car or truck electrical circuits such as audio systems, auxiliary power outlets, or battery feeds. Marine: Safeguards boat battery circuits and onboard electronics from short circuits and charge faults. General lowvoltage systems: Protects battery banks and accessory circuits in RVs, small offgrid setups, and equipment panels. Why it stands out The combination of clear visual trip indication, tool manual reset, broad lowvoltage compatibility, and robust materials makes this breaker a straightforward, dependable choice for preventing electrical faults and extending the life of lowvoltage systems.
