- The included components are XT1B 160 TMD 160-1600 4p F F InN=50%.
5. Operating Instructions
The circuit breaker is designed for straightforward operation.
5.1 Turning ON the Breaker
- Ensure all downstream loads are ready to receive power.
- Move the operating handle to the 'ON' position. The breaker is now closed, and power is supplied to the circuit.
5.2 Turning OFF the Breaker
- Move the operating handle to the 'OFF' position. This opens the circuit, disconnecting power to the load.
5.3 Trip Indication and Reset
- If an overload or short-circuit occurs, the breaker will automatically trip to protect the circuit. The operating handle will move to an intermediate 'TRIPPED' position.
- To reset a tripped breaker, first move the handle fully to the 'OFF' position, then move it to the 'ON' position.
- Investigate and resolve the cause of the trip before resetting the breaker to prevent further issues.
6. Maintenance
Regular maintenance helps ensure the longevity and reliable operation of your circuit breaker. Always disconnect power before performing any maintenance.
- Periodic Inspection: Visually inspect the breaker and its connections for any signs of damage, discoloration, or loose wiring.
- Cleaning: Keep the breaker free from dust and debris. Use a dry, lint-free cloth for cleaning. Do not use solvents or abrasive cleaners.
- Connection Checks: Periodically check terminal connections for tightness.
7. Troubleshooting
This section addresses common issues you might encounter with the circuit breaker.
