Product Description
Core features:
Intelligence: Built in Micrologic release, supports real-time monitoring (current, voltage, fault recording) and remote control, compatible with EcoStruxure platform.
High reliability: modular design, optional electronic/thermal magnetic protection, with a lifespan of tens of thousands of operations.
Comprehensive protection: Provides overload, short circuit, and ground fault protection, and supports selective coordination.
Flexible Expansion: Communication modules (Modbus, Ethernet) and auxiliary contacts can be installed.
Suitable for scenarios such as data centers, factories, and large buildings, known for high security, digital management, and low energy consumption, in compliance with IEC/GB standards.
The air circuit breaker monitors the current in the circuit in real-time through a current transformer. And transmit the current signal to the intelligent controller.
After the intelligent controller detects the abnormal current, it will disconnect the contacts inside the circuit breaker and cut off the circuit

·MTN, MTH800A to 6300A (except 4000A) have the same connection terminals;
There is no need to leave space for the front connection, as the terminals have not increased the depth of the circuit breaker;
·To connect on the horizontal or vertical busbar, simply turn the connection terminal 90 degrees.
Check whether the mechanical operation of the circuit breaker is flexible and reliable.
Test the operation functions such as closing, opening, and energy storage.
Electrical performance testing:
Insulation resistance test: Use a megohmmeter to measure the insulation resistance of the main and auxiliary circuits, ensuring that they meet the standard (usually ≥ 1M Ω).
Power frequency withstand voltage test: Apply rated power frequency voltage (such as 2500V/1min) to the main circuit and auxiliary circuit to check the insulation performance.
Contact resistance test: Measure the contact resistance of the main contact to ensure that it is below the specified value (usually micro ohm level).
Protection function test:
Test the action values and time of protection functions such as overload, short circuit, and ground fault.
Verify the settings and functionality of the intelligent release device.
Outer packaging:
Strong wooden boxes are usually used to provide sufficient mechanical strength.
Wooden crate suitable for large circuit breakers or international transportation
Inner packaging:
Wrap the circuit breaker with buffer materials such as foam pad, bubble film or pearl cotton to prevent vibration and collision.
For large circuit breakers, the packaging box may adopt a layered design, with accessories (such as manuals, tools, spare parts) placed on the upper layer
Domestic transportation
If there is a designated freight forwarder in china, we willtransport the products to the designated location through road transportation or domestic express delivery after production is completed
