AIR CIRCUIT BREAKER
MT/MVS
ACB (Air Circuit Breaker) is a high-performance low-voltage circuit breaker, with representative models including MT/NT and MVS series, covering rated currents of 630A~6300A, with a breaking capacity of up to 150kA, suitable for industrial, commercial, and energy distribution systems.
Core features:
Intelligence: Engineered with Micrologic release, this device supports real-time monitoring (current, voltage, fault recording) and remote control capabilities, fully compatible with the EcoStruxure platform.
High reliability: Boasts a modular design with optional electronic/thermal magnetic protection, promising a lifespan of tens of thousands of operations.
Comprehensive protection: Delivers robust overload, short circuit, and ground fault protection, with support for selective coordination.
Flexible Expansion:Communication modules (Modbus, Ethernet) and auxiliary contacts can be seamlessly integrated.
Ideal for deployment in data centers, factories, and large buildings, it is renowned for its high security, digital management, and energy efficiency, all adhering to IEC/GB standards.
Working principle:
The air circuit breaker continuously monitors the circuit's current through a precision current transformer, transmitting this data to the intelligent controller.
Upon detection of an abnormal current, the intelligent controller swiftly disconnects the internal contacts of the circuit breaker to interrupt the circuit effectively.

Installation Instructions
· The MTN and MTH800A to 6300A models (excluding the 4000A variant) are designed with identical connection terminals, ensuring seamless integration. These models feature the same connection terminals, providing consistency and ease of use.;
With the innovative design of our circuit breakers, there's no need to allocate additional space for the front connection, as the terminal size does not affect the depth of the breaker.
· Whether you're connecting to a horizontal or vertical busbar, our connection terminals offer unmatched flexibility by allowing a simple 90-degree rotation. Simply rotate the terminal by 90 degrees for a flawless connection.
Mechanical operation test: Conducting comprehensive checks to guarantee seamless functionality.
Check whether the mechanical operation of the circuit breaker is meticulously flexible and reliable.
Test the operation functions, ensuring flawless performance for closing, opening, and energy storage.
Electrical performance testing: Assessing the circuit breaker's electrical robustness and safety.
Insulation resistance test: Utilize a megohmmeter to ascertain the insulation resistance of the main and auxiliary circuits, confirming they exceed the standard (typically ≥ 1M Ω).
Power frequency withstand voltage test: Apply the rated power frequency voltage (e.g., 2500V/1min) to the main and auxiliary circuits to evaluate insulation integrity.
Contact resistance test: Measure the contact resistance of the main contact to ensure it remains below the specified threshold (usually at a micro ohm level).
Protection function test: Comprehensive verification of the system's protective capabilities.
Test the action values and timing of critical protection functions, such as overload, short circuit, and ground fault.
Verify the precise settings andfunctionality of the intelligent release device, ensuring smart and reliable operation.
