2. د خوندیتوب معلومات

خبرداری: د بریښنا شاک یا اور خطر.

• Installation and servicing of this circuit breaker must be performed by qualified electrical personnel only.
• تل د بریښنایی تجهیزاتو کار کولو دمخه د اصلي خدماتو پینل کې بریښنا قطع کړئ. د حجم په کارولو سره تایید کړئ چې بریښنا بنده دهtage ټیسټر.
• ټول محلي او ملي بریښنا کوډونه او مقررات تعقیب کړئ.
• Do not use this circuit breaker if it appears damaged.
• Ensure proper wire sizing and torque specifications are met for all connections.

3. د محصول ب Featuresې

The Siemens B2125 is a reliable thermal-magnetic circuit breaker designed for panel board mounting. Key features include:

• Type BL: Specifically designed for Siemens panel boards.
• Double Pole: Provides protection for two electrical phases or a single 240-volt circuit.
• 125-Amp درجه بندي: Suitable for circuits requiring up to 125 amperes of protection.
• 10KAIC Interrupting Rating: Capable of safely interrupting fault currents up to 10,000 Amperes
• Bolt-On Mount: Ensures secure and stable connection within the panel board.
• UL لیست شوی: Certified for safety and performance standards.

4. ترتیب او نصب کول

Installation of the Siemens B2125 circuit breaker requires adherence to safety protocols and electrical codes. This is a general guide; consult a qualified electrician for specific installation requirements.

1. د بریښنا قطع کول: Turn off the main power supply to the electrical panel at the utility meter or main disconnect. Verify zero voltage د مناسب ازموینې وسیلې سره.
2. د پینل لاسرسی: د بریښنایی تختې پوښ په احتیاط سره لرې کړئ ترڅو د بس بارونه او د تارونو ساحه ښکاره شي.
3. Breaker Placement: Identify an available space on the panel board's bus bar compatible with a bolt-on type BL breaker.
4. پورته کول: Align the circuit breaker's bolt-on connectors with the bus bar terminals. Securely fasten the breaker to the bus bar using the provided bolts, ensuring a tight electrical connection.
5. تارونه: Connect the load wires to the appropriate terminals on the circuit breaker. For a double pole breaker, connect one phase wire to each terminal. Ensure the wires are stripped to the correct length and inserted fully into the terminals. Tighten the terminal screws to the torque specifications indicated on the breaker or in the panel documentation.
6. د تختې پوښ: Once all connections are secure and verified, replace the electrical panel cover.
7. د بریښنا بیا رغونه: د خدماتو اصلي پینل ته بریښنا بیرته ورکړئ.

5. عملیاتي لارښوونې

The Siemens B2125 circuit breaker operates automatically to protect electrical circuits from overcurrents and short circuits. It has two primary states: ON and TRIPPED/OFF.

• په موقف: When the handle is in the 'ON' position, power is supplied through the breaker to the connected circuit.
• د سفر حالت: In the event of an overcurrent or short circuit, the breaker will automatically move to a 'TRIPPED' position (often midway between ON and OFF) to interrupt the power flow and protect the circuit.
• د ټریپ شوي بریکر بیا تنظیم کول: To restore power after a trip, first move the handle fully 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 needs to be investigated by a qualified electrician.

6. ساتنه

Circuit breakers generally require minimal maintenance. However, periodic visual inspection is recommended.

• بصری معاینه: Annually, or as local codes require, have a qualified electrician inspect the circuit breaker and its connections for any signs of overheating, loose wires, or physical damage.
• پاکول: Ensure the area around the breaker is free from dust and debris. Do not use liquids for cleaning inside the electrical panel.
• ازموینه: Do not routinely test the trip mechanism by intentionally creating a fault. This can stress the breaker and connected equipment.

7. ستونزه حل کول

If your Siemens B2125 circuit breaker is not functioning as expected, consider the following:

• د ماتونکي سفرونه اکثرا: This indicates an overload or a short circuit in the connected wiring or appliances. Disconnect appliances from the circuit and try resetting the breaker. If it still trips, consult a qualified electrician to identify and resolve the underlying electrical fault.
• ماتونکی بیا نه تنظیمیږي: If the breaker handle does not stay in the 'ON' position after being moved to 'OFF' and then 'ON', there is likely a persistent fault. Do not force the handle. Contact a qualified electrician.
• د سرکټ لپاره بریښنا نشته (بریکر آن): Ensure the main power supply to the panel is active. Check for loose connections at the breaker terminals (only by a qualified electrician with power off). If the issue persists, professional diagnosis is required.
