1. Product Overview
The CEYYOR Resettable Circuit Breaker is a high-quality circuit protective device designed for 12-42VDC systems. Constructed from durable alloy material, it offers excellent electrical conductivity and high-temperature resistance, ensuring reliable power protection for various applications including automotive, marine, and audio systems. This breaker eliminates the need to replace fuses, as it can be manually reset after an overload condition.
2. Package Contents
Please check the package for the following items:
- 1 x CEYYOR Resettable Circuit Breaker (selected amperage)
- Installation accessories (may include screws, heat shrink tubing, ring terminals, washers)
3. Setup and Installation
Safety Warning: Always disconnect the power source before installing or servicing any electrical components to prevent electric shock or damage to equipment.
- Choose Mounting Location: Select a dry, secure location close to the power source (e.g., battery) that is protected from direct water exposure and excessive heat.
- Mount the Breaker: Securely fasten the circuit breaker using appropriate screws. Ensure the mounting surface is flat to prevent stress on the breaker housing.
- Wiring: Connect the circuit breaker according to the wiring diagram provided.
- The terminal marked 'BAT' (or similar, often indicated by a '+' symbol) connects to the positive (+) terminal of your power source (e.g., battery).
- The terminal marked 'AUX' (or similar, often indicated by a '-' symbol or load side) connects to the positive (+) input of the device or circuit you wish to protect.
- Ensure all connections are tight and secure to prevent arcing and overheating. Use appropriate wire gauges for your selected amperage.
- Test Installation: Once wired, reconnect the power source and test the circuit.

4. Operating Instructions
Automatic Operation
The circuit breaker is designed to automatically trip (open the circuit) when the current flowing through it exceeds its rated amperage for a sustained period. This protects your electrical system from overloads and short circuits.
Manual Reset
If the breaker trips, the red reset lever will typically pop out. To reset the breaker:
- Identify and resolve the cause of the overload or short circuit.
- Push the red reset lever back into its original position until it clicks.
Manual Trip
The circuit breaker also features a manual trip button (usually a smaller red button). Pressing this button will manually trip the breaker, opening the circuit. This can be used to disconnect power to a circuit for maintenance or safety.
5. Maintenance
- Regular Inspection: Periodically inspect the circuit breaker and its connections for any signs of damage, corrosion, or loose wiring.
- Clean Terminals: Ensure the terminals are clean and free from dirt or corrosion. Use a non-abrasive cleaner if necessary.
- Tighten Connections: Verify that all electrical connections remain tight. Loose connections can cause resistance, heat buildup, and potential failure.
- Environmental Protection: While designed to be robust, avoid exposing the breaker to extreme moisture or corrosive environments for prolonged periods.
6. Troubleshooting
- Breaker Trips Frequently:
- Cause: The circuit is overloaded, or there is a short circuit.
- Solution: Reduce the load on the circuit, or inspect the wiring and connected devices for a short circuit. Ensure the breaker's amperage rating matches the circuit's requirements.
- Breaker Does Not Reset:
- Cause: A severe overload or internal damage to the breaker.
- Solution: Disconnect power to the circuit. If the breaker still does not reset, it may be damaged and require replacement. Do not force the reset lever.
- No Power to Circuit, Breaker Not Tripped:
- Cause: Loose connection, faulty wiring, or a problem with the power source or load.
- Solution: Check all connections, wiring, and the functionality of the power source and the device being powered.

8. User Tips
- Match Amperage: Always select a circuit breaker with an amperage rating appropriate for the circuit it is protecting. An undersized breaker will trip frequently, while an oversized one may not provide adequate protection.
- Proper Wire Gauge: Use the correct wire gauge for the current draw of your circuit. Undersized wires can overheat and cause fires, even with a properly rated breaker.
- Secure Mounting: Ensure the breaker is mounted firmly to prevent vibration damage, especially in automotive or marine environments.
- Polarity: Pay close attention to polarity during installation (BAT to positive source, AUX to positive load).
