2. Safety Information
WARNING: Risk of electric shock or fire. Installation and servicing should be performed by qualified personnel only. Disconnect all power sources before installation or servicing.
- Always wear appropriate personal protective equipment (PPE) when working with electrical systems.
- Ensure the circuit breaker's amperage rating matches the circuit requirements.
- Do not use this device in environments exceeding its specified operating conditions.
- Verify all connections are secure and properly insulated to prevent short circuits.
- Do not attempt to bypass or modify the circuit breaker's protective functions.
3. Installation
Proper installation is crucial for the safe and effective operation of the circuit breaker. Refer to the wiring diagram provided with your specific application or panel for correct connections.
- Power Disconnection: Ensure all power to the circuit where the breaker will be installed is completely disconnected. Use a voltmeter to confirm zero voltage.
- Mounting: Mount the circuit breaker securely in an appropriate panel or enclosure. Ensure adequate ventilation and protection from environmental factors if not rated for exposed conditions.
- Wiring: Connect the input (source) wire to the designated terminal and the output (load) wire to the other terminal. Observe correct polarity if applicable. Use appropriately sized wire for the 30 Amp rating.
- Terminal Security: Tighten all terminal screws to the manufacturer's specified torque settings. Over-tightening can damage terminals, while under-tightening can lead to poor connections and overheating.
- Verification: Double-check all wiring for correctness and security before restoring power.

4. Operation
The C-Series 7355 circuit breaker operates as a simple ON/OFF switch with integrated overcurrent protection.
- To Turn ON: Push the toggle switch to the "ON" position. This closes the circuit, allowing current to flow.
- To Turn OFF: Push the toggle switch to the "OFF" position. This opens the circuit, stopping current flow.
- Trip Condition: If an overcurrent condition occurs, the circuit breaker will automatically trip to the "OFF" position, interrupting the circuit. Due to its "Trip Free" design, it cannot be held in the "ON" position if an overcurrent condition persists.
- Resetting After a Trip: Before resetting, identify and resolve the cause of the overcurrent. Once the issue is resolved, push the toggle switch firmly to the "OFF" position, then to the "ON" position to reset the breaker.
5. Maintenance
The Blue Sea Systems C-Series 7355 circuit breaker requires minimal maintenance. Regular inspection is recommended to ensure continued reliable operation.
- Visual Inspection: Periodically inspect the breaker for any signs of physical damage, discoloration, or corrosion.
- Connection Check: Ensure all electrical connections remain tight and secure. Loose connections can cause resistance, heat, and potential failure.
- Cleaning: If necessary, gently clean the exterior of the breaker with a dry, lint-free cloth. Do not use abrasive cleaners or solvents.
- Environmental Protection: Ensure the breaker remains protected from excessive moisture, dust, and extreme temperatures, especially if not rated for harsh environments.
6. Troubleshooting
If the circuit breaker is not functioning as expected, consider the following common issues:
| Symptom | Possible Cause | Action |
|---|---|---|
| Breaker trips frequently | Overload on the circuit, short circuit, faulty appliance/device. | Reduce load, inspect wiring for shorts, test connected devices. |
| Breaker does not reset | Persistent overcurrent/short circuit, internal breaker fault. | Ensure the cause of the trip is resolved. If it still doesn't reset, the breaker may be faulty and require replacement. |
| No power to circuit when ON | Loose connections, faulty wiring, upstream power issue, internal breaker fault. | Check all connections, verify power supply to the breaker, test the breaker for continuity (with power off). |
If troubleshooting steps do not resolve the issue, consult a qualified electrician or contact Blue Sea Systems customer support.
