200A ManualReset Circuit Breaker — Key Benefits and Features Why you need it Provides reliable overcurrent protection for 200A circuits, preventing damage to wiring, fuse holders, and connected equipment from power draw or short circuits. Manual reset lever doubles as an accessible kill switch for quickly isolating power during maintenance or emergencies. Durable, weatherproof construction ensures dependable performance in demanding environments. What it does Trips automatically on overcurrent or shortcircuit events, then requires a manual reset to restore power, preventing repeated cycling and giving you control over system recovery. Acts as an emergency shutoff (kill switch) when you need to cut power immediately and safely. Key attributes Rating: 200A manualreset circuit breaker. Housing: UL‑rated thermoplastic, flameretardant for improved safety. Sealing: IP67 waterproof protection for use in wet or dusty conditions. Hardware: Alloy screws for efficient electrical conduction and corrosion resistance. Mounting: Designed for secure panel or firewall mounting for convenient access. Performance and compatibility Engineered for use in 200A power distribution applications where a resettable overcurrent device and an easytoreach shutoff are required. Robust materials and IP67 rating make it suitable for environments exposed to moisture and contaminants while maintaining electrical safety. ULrated housing supports safe installation in systems that require recognized safety materials. Practical applications (examples) Marine and boating electrical systems: Provide 200A protection for battery banks and shore power connections while withstanding wet environments. RVs and overland vehicles: Protect current circuits and provide an accessible kill switch at the panel or firewall. Batterybased and offgrid power systems: Isolate and protect 200A inverter, charger, or distribution circuits from overloads and shorts. What makes it stand out Combines a 200A protection rating with a manual reset/killswitch function for both safety and operational control. Flameretardant, ULrated thermoplastic housing plus IP67 waterproofing for reliable use across a range of environments. Alloy screw terminals deliver solid conductivity and longterm durability. Installation notes Mount on a panel or firewall for quick access to the manual reset lever and emergency shutoff. Ensure breaker rating and system wiring are matched to 200A capacity and follow applicable electrical codes for safe operation and installation.
