GE TB43225AF14 3-pole circuit breaker
GE TB43225AF14 3-pole circuit breaker
The GE TB43225AF14 is a 3-pole circuit breaker manufactured by General Electric3. It has the following features3:
Basic Specifications
Connection Type: Bolt-on, which ensures a reliable electrical connection and is convenient for installation and maintenance.
Rated Voltage: 600V, suitable for various medium-voltage power distribution systems.
Rated Current: 225A, capable of handling the normal load current of the circuit.
Interrupt Rating: 200kA at 480V, indicating its excellent ability to break high short-circuit currents and protect the power system from damage caused by short circuits.
Protection Functions
Thermal Magnetic Protection: It combines thermal and magnetic protection functions. The thermal element is used to protect against overloads, responding to long-term overcurrent conditions by tripping the breaker after a certain time delay. The magnetic element is designed to quickly trip the breaker in the event of a short circuit, providing rapid protection against high fault currents.
Trip Unit and Function
Trip Unit Type: Interchangeable trip, which offers flexibility in different application scenarios. Users can replace the trip unit according to specific requirements to adapt to different load characteristics and protection needs.
Functions: It has long-time and instantaneous protection functions, abbreviated as "li". The long-time protection function is used to protect the circuit from overloads, and the instantaneous protection function is used to quickly cut off the circuit when a short circuit fault occurs.
Product Family and Type
Family: It belongs to the Tri-Break family, known for its reliable performance and high-quality design in the circuit breaker product line of General Electric.
Type: TB43, which represents a specific series of circuit breakers with unique technical characteristics and design standards.
In summary, the GE TB43225AF14 3-pole circuit breaker is a high-performance electrical protection device that plays a crucial role in ensuring the safe and stable operation of power distribution systems.
Precautions for Use
Installation Environment: It should be installed in a dry, well - ventilated, dust - free, and non - corrosive gas environment. Avoid installing it in places with high temperature, high humidity, vibration, or strong electromagnetic interference.
Wiring Specifications: Wire strictly in accordance with the specifications and requirements of the terminal strip to ensure that the wires are firmly connected and avoid problems such as loose connections or short - circuits.
Load Matching: Select an appropriate power terminal strip according to the power and current requirements of the connected devices to ensure that it can bear the corresponding load.
Regular Maintenance: Regularly inspect and maintain the power terminal strip, clean dust and debris, check for loose connections, and promptly detect and address potential problems.
