2. Informații de siguranță

AVERTISMENT: Risc de electrocutare sau incendiu.

• Installation and servicing of this circuit breaker must be performed by qualified electrical personnel only.
• Always disconnect power at the main service panel before working on electrical equipment. Verify that power is off using a voltage tester.
• Respectați toate codurile și reglementările electrice locale și naționale.
• Do not use this circuit breaker if it appears damaged.
• Ensure proper wire sizing and torque specifications are met for all connections.

3. Caracteristicile produsului

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 Evaluare: 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.
• Listat UL: Certified for safety and performance standards.

4. Configurare și instalare

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. Deconectare de la curent: Turn off the main power supply to the electrical panel at the utility meter or main disconnect. Verify zero voltage with a suitable testing device.
2. Acces la panou: Carefully remove the cover of the electrical panel to expose the bus bars and wiring area.
3. Amplasarea întrerupătorului: Identify an available space on the panel board's bus bar compatible with a bolt-on type BL breaker.
4. Montare: 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. Cablaj: 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. Capacul panoului: După ce toate conexiunile sunt fixate și verificate, puneți la loc capacul panoului electric.
7. Restaurarea energiei: Reconectați alimentarea la panoul principal de service.

5. Instrucțiuni de utilizare

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.

• Poziția ON: When the handle is in the 'ON' position, power is supplied through the breaker to the connected circuit.
• Poziție DECLINATĂ: 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.
• Resetarea unui întrerupător declanșat: 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. Întreținere

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

• Inspecție vizuală: 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.
• curatenie: Ensure the area around the breaker is free from dust and debris. Do not use liquids for cleaning inside the electrical panel.
• Testare: Do not routinely test the trip mechanism by intentionally creating a fault. This can stress the breaker and connected equipment.

7. Depanare

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

• Frecvența declanșărilor întrerupătorului: 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.
• Întrerupătorul nu se resetează: 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.
• Fără alimentare cu energie electrică la circuit (întrerupător activat): 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.

9. Informații despre garanție

Siemens strongly recommends against the use of "used" breakers. The installation of used breakers in a Siemens panel will void the warranty on the panel. Siemens does not sell used breakers and has not approved any third-party sellers to do so. For specific warranty details, please refer to the official Siemens warranty documentation or contact Siemens customer support.
