Product Description

Product Description

AIR CIRCUIT BREAKER

MT/MVS

ACB (Air Circuit Breaker) is a remarkably high-performance low-voltage circuit breaker. Its standout models include the MT/NT and MVS series, which encompass an impressive range of rated currents from 630A to 6300A, boasting a formidable breaking capacity reaching up to 150kA, perfectly suited for industrial and commercial, as well as energy distribution systems.

Core features:
Intelligence: Equipped with an advanced Micrologic release, enabling real-time monitoring that includescurrent, voltage, and fault recording) enhanced by remote control capabilities, fully compatible with the EcoStruxure platform.

High reliability: Features a modular design with the choice of electronic or thermal magnetic protection, ensuring a lifespan of tens of thousands of operations.

Comprehensive protection: Delivers protection against overloads, short circuits, and ground faults, while supporting selective coordination to optimize safety.

Flexible Expansion:Offers installation of communication modules likeModbus and Ethernet) along with auxiliary contacts for enhanced adaptability.

Perfectly suited for environments such as data centers, factories, and large buildings. Renowned for its high security, digital management capabilities, and low energy consumption, all in strict compliance with IEC/GB standards.

 

Working principle:

The air circuit breaker continuously monitors current flow in real-time through a current transformer, transmitting the current signal to the intelligent controller.

Upon detecting any abnormal current, the intelligent controller promptly disconnects the contacts within the circuit breaker to interrupt the circuit, ensuring safety and reliability.

Product testing

Rigorous Mechanical Operation Test:

Conduct an in-depth check to ensure that the mechanical operation of the circuit breaker is not only flexible but also unfailingly reliableunder all conditions.

Meticulously test each operation function, including closing, opening, as well as energy storage, ensuring seamless performance.

Comprehensive Electrical Performance Testing:

Perform an insulation resistance test using a high-precision megohmmeter to measure the insulation resistance of the main and auxiliary circuits, ensuring strict compliance with standards (typically ≥ 1M Ω).

Execute a power frequency withstand voltage test by applying rated power frequency voltage (such as 2500V/1min) to both the main and auxiliary circuits, to scrutinize the insulation performance meticulously.

Conduct a contact resistance test to measure the contact resistance of the main contact, ensuring it remains below the stringent specified value (usually at a micro ohm level for optimal efficiency).

Thorough Protection Function Test:

Diligently test the action values and response times of critical protection functions, including overload, short circuit as well as ground faultprotection.

Carefully verify the precise settings androbust functionality of the intelligent release device, ensuring it meets all operational expectations.

 

Packaging & Shipping

Outer Packaging Excellence:

Robust wooden crates are predominantly utilized to offer exceptional mechanical durability.

Our meticulously crafted wooden crates are ideal for large circuit breakers or for international shipping.

Inner Packaging Precision:
