3. Mahsulot xususiyatlari
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 Reyting: 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 ro'yxati: Certified for safety and performance standards.
4. O'rnatish va o'rnatish
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.
- Quvvatni uzish: Turn off the main power supply to the electrical panel at the utility meter or main disconnect. Verify zero voltage mos sinov qurilmasi bilan.
- Panelga kirish: Elektr paneli qopqog'ini ehtiyotkorlik bilan olib tashlang, shunda avtobus panjaralari va simlar maydoni paydo bo'ladi.
- To'xtatuvchini joylashtirish: Identify an available space on the panel board's bus bar compatible with a bolt-on type BL breaker.
- O'rnatish: 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.
- Elektr simlari: 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.
- Panel qopqog'i: Once all connections are secure and verified, replace the electrical panel cover.
- Quvvatni tiklash: Asosiy xizmat paneliga quvvatni tiklang.

5. Foydalanish bo'yicha ko'rsatmalar
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.
- ON holati: When the handle is in the 'ON' position, power is supplied through the breaker to the connected circuit.
- TRIPPED holati: 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.
- O'chirilgan to'xtatuvchini qayta o'rnatish: 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. Xizmat ko'rsatish
Circuit breakers generally require minimal maintenance. However, periodic visual inspection is recommended.
- Vizual tekshirish: 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.
- Tozalash: Ensure the area around the breaker is free from dust and debris. Do not use liquids for cleaning inside the electrical panel.
- Sinov: Do not routinely test the trip mechanism by intentionally creating a fault. This can stress the breaker and connected equipment.

7. Muammolarni bartaraf qilish; nosozliklarni TUZATISH
If your Siemens B2125 circuit breaker is not functioning as expected, consider the following:
- To'xtatuvchining tez-tez sayohatlari: 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.
- To'xtatuvchi qayta tiklanmaydi: 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.
- O'chirish uchun quvvat yo'q (O'chirgich ON): 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.
