4. ترتیب او نصب کول

The Siemens BQD345 circuit breaker is designed for bolt-in installation within a compatible panel board. Installation must be performed by a qualified electrician in accordance with all applicable electrical codes.

1. د بریښنا قطع کول: Before beginning any work, ensure that all power to the electrical panel is completely disconnected at the main service entrance. Verify with a voltage ټیسټر.
2. Panel Access: Carefully remove the cover of the electrical panel to expose the bus bars and wiring area.
3. پورته کول: Position the BQD345 circuit breaker onto the designated bus bar connections in the panel board. Securely fasten the breaker using the bolt-in mechanism.
4. تارونه: Connect the load wires to the appropriate terminals on the circuit breaker. Refer to the breaker's label for correct wire sizing (e.g., for 45A, Cu-Al 60°/75°C wire, size 8 AWG for 45A). Ensure all connections are tight and secure.
5. Panel Reassembly: Once wiring is complete and verified, replace the panel cover.
6. د بریښنا بیا رغونه: Restore power at the main service entrance.

For detailed wiring diagrams and specific panel compatibility, consult the panel board manufacturer's instructions and relevant electrical codes.

5. عملیاتي لارښوونې

The BQD345 circuit breaker features a toggle handle that indicates its current status:

• په: The handle is in the 'ON' position, indicating that power is flowing through the circuit.
• بند: The handle is in the 'OFF' position, indicating that power to the circuit is disconnected.
• سفر: If an overcurrent or short circuit condition occurs, the breaker will automatically move to the 'TRIP' position (typically a central position between ON and OFF). This indicates that the circuit has been interrupted for safety.

To reset a tripped breaker: First, move the handle completely to the 'OFF' position, then push it firmly to the 'ON' position. If the breaker immediately trips again, there is likely a persistent fault in the circuit that requires investigation by a qualified electrician.

6. ساتنه

Regular maintenance helps ensure the longevity and reliable operation of your circuit breaker. All maintenance should be performed by qualified personnel with power disconnected.

• بصری معاینه: Periodically inspect the circuit breaker and its connections for any signs of overheating, discoloration, loose wires, or physical damage.
• پاکول: Keep the area around the circuit breaker clean and free of dust and debris. Use a dry, non-conductive cloth for cleaning.
• ازموینه: While not typically required for residential or light commercial applications, some industrial standards may require periodic testing of circuit breakers. Consult relevant standards and a qualified electrician for such requirements.

7. ستونزه حل کول

If your Siemens BQD345 circuit breaker is not functioning as expected, consider the following:

• د ماتونکي سفرونه اکثرا: This indicates an overcurrent condition or a short circuit in the protected circuit. Disconnect all loads from the circuit and try resetting the breaker. If it still trips, there is a fault in the wiring or a connected appliance. Consult a qualified electrician.
• ماتونکی به بیا تنظیم نشي: Ensure the handle is pushed fully to the 'OFF' position before attempting to move it to 'ON'. If it still won't reset, or immediately trips, a fault is present.
• No Power to Circuit (Breaker ON): Check the main service panel for tripped main breakers. Verify all connections to the BQD345 are secure. If the issue persists, professional electrical diagnosis is required.

Do not attempt to force a breaker into the ON position if it resists or immediately trips. This can indicate a serious electrical fault.
