Product Description

Product Description

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: 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.

 

Working principle:

The air circuit breaker monitors the current in the circuit in real-time through a current transformer, transmitting 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

Installation Instructions

· For the MTN and MTH models ranging from 800A to 6300A (excluding 4000A), you will find a consistent design with the same connection terminals, ensuring simplified setup and enhanced compatibility across different installations.;
No additional space is necessary for front connections, as the terminals are ingeniously designed to maintain the circuit breaker's original depth.
· Whether you are connecting to horizontal or vertical busbars, our versatile design allows the connection terminal to be rotated a seamless 90 degrees for effortless and adaptable installation.

Product testing

1. Rigorous Mechanical Operation Test:

Ensure the circuit breaker's mechanical operation is smooth, agile, andconsistently reliable.

Evaluate operation functions including seamless closing, precise opening,and efficient energy storage.

2. Comprehensive Electrical Performance Testing:

• Insulation Resistance Test: Employ a megohmmeter to assess insulation resistance of the primary and auxiliary circuits, ensuring adherence to standards (typically ≥ 1M Ω).

• Power Frequency Withstand Voltage Test: Administer rated power frequency voltage (e.g., 2500V/1min) to both main and auxiliary circuits to verify superior insulation performance.

• Contact Resistance Test: Accurately measure contact resistance of the main contact, guaranteeing it remains below the defined value (usually at the micro ohm level).

3. Robust Protection Function Test:

Evaluate the activation thresholds and timings of protection functions encompassing overload, short circuit scenarios, as well as ground fault conditions.

Confirm the precision settings andflawless functionality of the state-of-the-art intelligent release device.

 

Packaging & Shipping

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:
