250A Heavy duty Manual Reset Circuit Breaker

250A high-amp manual reset circuit breaker is a splash-proof (IP67) thermal device designed for 12V-48V DC systems, commonly used in marine, RV, and heavy-duty automotive applications to protect against overloads. It features a manual switchable button to reset, often with a push-to-trip lever, designed for surface mounting with 5/16"-18 studs.

Key Features and Operating Instructions:

• Protection: Guards against excessive current, protecting inverters, motors, and battery systems.
• Manual Reset: When the circuit trips due to overload, it can be manually reset, eliminating the need to replace fuses.
• Switchable: The button on the unit can also act as a manual master disconnect switch.
• Installation: Surface mount with 5/16" (8mm) stud terminals suitable for high-torque connections.
• Environment: Rated IP67 for water and dust resistance, making it suitable for harsh, exposed environments.
• Temperature Rating: Typically functions between -32°C to 82°C (-25°F to 180°F). 

Usage Precautions:

• Ensure the circuit breaker is installed in a location accessible for manual resetting.
• Use appropriate cable gauge for 250A load to prevent overheating at terminals.
• Push the reset button correctly to avoid damaging the mechanism.
