Product Description

Product Description

AIR CIRCUIT BREAKER

MT/MVS

ACB (Air Circuit Breaker) is a high-performance low-voltage circuit breaker, with flagship models such as MT/NT and MVS series, covering an extensive range of rated currents from 630A to 6300A, boasting a remarkable breaking capacity of up to 150kA, making it ideal for use in industrial, commercial, and energy distribution systems.

Core features:
Intelligence: Incorporates a sophisticated Micrologic release, enabling real-time monitoring (current, voltage, fault recording) and facilitating remote control, seamlessly integrates with EcoStruxure platform.

High reliability: Features a robust modular design, offers optional electronic/thermal magnetic protection, with an enduring operational lifespan of tens of thousands of operations.

Comprehensive protection: Delivers advanced overload, short circuit, and ground fault protection, and supports selective coordination for enhanced system reliability.

Flexible Expansion:Equipped with versatile communication modules (Modbus, Ethernet) and supports installation of auxiliary contacts.

Perfectly tailored for environments such as data centers, factories, and large buildings, renowned for high security, digital management, and energy efficiency, ensuring compliance with stringent IEC/GB standards.

 

Working principle:

The air circuit breaker vigilantly monitors circuit current in real-time through a current transformer and transmits the data to the intelligent controller.

Upon detecting any abnormal current, the intelligent controller swiftly disconnects the internal contacts, effectively cutting off the circuit

Installation Instructions

·The MTN and MTH series, ranging from 800A to a robust 6300A (excluding 4000A), feature innovative connectivity with identical connection terminals for seamless integration.;
No additional space is required for front connection, as the specially designed terminals maintain the existing depth of the circuit breaker;
·Adaptability is key: for versatile installation on either horizontal or vertical busbars, effortlessly rotate the connection terminal by 90 degrees to achieve perfect alignment.

Product testing

Comprehensive Mechanical Operation Tests:

Ensure that the mechanical operation of the circuit breaker is incredibly flexible as well as consistently reliable.

We meticulously assess operation features such as seamless closing, smooth opening, and efficient energy storage.

Stringent Electrical Performance Testing:

Insulation Resistance Test: Utilize a state-of-the-art megohmmeter to measure the insulation resistance of both main and auxiliary circuits, ensuring compliance with stringent standards (typically ≥ 1M Ω).

Power Frequency Withstand Voltage Test: Apply the rated power frequency voltage, such as 2500V/1min, to both the main and auxiliary circuits to scrutinize insulation performance under challenging conditions.

Contact Resistance Test: Accurately measure the contact resistance of the main contact to affirm it remains below the stringent specified threshold (commonly at the micro ohm level).

Robust Protection Function Tests:

Evaluate the precise action values and timing of protection features, including overload, short circuit, and ground fault.

Thoroughly validate the configuration settings androbust functionality of the sophisticated intelligent release device.

 

Packaging & Shipping

Outer packaging:

For superior protection, we employ strong wooden boxes that are meticulously crafted to provide exceptional mechanical strength.

These robust wooden crates are especially suitable for large circuit breakers or international transportation needs.

Inner packaging:

To ensure impeccable safety, we envelop the circuit breaker in premium buffer materials like foam pads, bubble films or pearl cotton , effectively guarding against any vibration and collision.

For larger circuit breakers, our packaging design incorporates a layered structure, elegantly housing accessories such as manuals, tools, and spare parts) in the upper compartment.
