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. 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

Installation Instructions

·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.

Product testing

Mechanical operation test:

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.

 

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:

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

International transport

When the quantity of goods is small and time is tight, and it needs to be transported to a designated location abroad, the three majorinternational express delivery companies are selected for transportation
DHL,FEDEX,UPS

Sea freight/air freight
When there is a large quantity of goods and time is not urgent, we choose sea freight. We will choose a suitable freight company, who wil arrange for trucks to pick up the goods and transport them to the designated por for warehousing. Finaly, they will transpored by sea to the customer's desianated port, and the customer needs to pick up the goods with a bill of lading.
