1. Introduktion

This manual provides essential information for the safe installation, operation, and maintenance of the Siemens B2125 125-Amp Double Pole Circuit Breaker. Please read this manual thoroughly before attempting any installation or operation. Retain this manual for future reference.

2. Sikkerhedsoplysninger

ADVARSEL: Risiko for elektrisk stød eller brand.

• 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.
• Følg alle lokale og nationale elektriske forskrifter og bestemmelser.
• Do not use this circuit breaker if it appears damaged.
• Ensure proper wire sizing and torque specifications are met for all connections.

3. Produktfunktioner

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 Bedømmelse: Suitable for circuits requiring up to 125 amperes of protection.
• 10KAIC Afbrydelsesvurdering: Kan sikkert afbryde fejlstrømme på op til 10,000 Amperes.
• Bolt-On Mount: Ensures secure and stable connection within the panel board.
• UL-listet: Certified for safety and performance standards.

4. Opsætning og installation

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. Strømafbrydelse: 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. Paneladgang: Carefully remove the cover of the electrical panel to expose the bus bars and wiring area.
3. Placering af afbryder: Identify an available space on the panel board's bus bar compatible with a bolt-on type BL breaker.
4. Montering: 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. Ledningsføring: 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. Paneldæksel: Når alle forbindelser er sikre og verificeret, skal du sætte dækslet til det elektriske panel på igen.
7. Strømgendannelse: Genopret strømmen til hovedservicepanelet.

5. Betjeningsvejledning

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 position: When the handle is in the 'ON' position, power is supplied through the breaker to the connected circuit.
• UDLØST position: 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.
• Nulstilling af en udløst afbryder: 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. Vedligeholdelse

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

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

7. Fejlfinding

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

• Ofte ture med breaker: 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.
• Afbryderen nulstilles ikke: 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.
• Ingen strøm til kredsløbet (afbryder tændt): 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. Garantioplysninger

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.
