Product Description

AIR CIRCUIT BREAKER

MT/MVS

ACB (Air Circuit Breaker) is a state-of-the-art high-performance low-voltage circuit breaker, featuring renowned models such as MT/NT and MVS series, expertly designed to handle rated currents ranging from 630A to 6300A, boasting a remarkable breaking capacity of up to 150kA, making it the ideal choice for industrial, commercial, and energy distribution systems.

Core features:
Intelligence: Equipped with an advanced Micrologic release, it supports comprehensive real-time monitoring (includingcurrent, voltage, and fault recording) and offers seamless remote control, fully compatible with the groundbreaking EcoStruxure platform.

High reliability: Features a modular design, offers optional electronic or thermal magnetic protection, and boasts a lifespan of tens of thousands of operations, ensuring unrivaled reliability.

Comprehensive protection: Delivers robust overload, short circuit, and ground fault protection, and supports selective coordination for maximum safety.

Flexible Expansion:Easily upgradable with communication modules (Modbus, Ethernet) and auxiliary contacts for versatile functionality.

Perfect for critical environments like data centers, factories, and large buildings, it stands out for its high security, digital management capabilities, and energy-efficient performance, all while meeting strict IEC/GB standards.

 

Working principle:

This sophisticated air circuit breaker monitors circuit current 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 safely cut off the circuit, ensuring system integrity and protection.

Installation Instructions

·For the MTN and MTH series, ranging from 800A to 6300A (except for 4000A), these models feature the same connection terminals, ensuring seamless integration and minimal fuss during installation.;
With innovative design, there's no requirement to reserve space for front connections, as our terminals are engineered to maintain the circuit breaker's compact depth;
·Effortlessly connect to either horizontal or vertical busbars by simply rotating the connection terminal 90 degrees, catering to diverse electrical setups with ease and precision.

Product testing

Mechanical operation test:

Check whether the mechanical operation of the circuit breaker is flexible, ensuring seamless operation that is reliable.

Test the operation functions meticulously, including closing,ensuring smooth initiation, and opening,guaranteeing swift disengagement, as well as energy storagefor dependable performance.

Electrical performance testing:

Insulation resistance test: Utilize a precise megohmmeter to measure the insulation resistance of both main and auxiliary circuits, ensuring superior compliance with standards (typically ≥ 1M Ω).

Power frequency withstand voltage test: Apply the rated power frequency voltage (for instance, 2500V/1min) to the main and auxiliary circuits, verifying top-notch insulation performance.

Contact resistance test: Accurately measure the contact resistance of the main contact to confirm it remains below the established threshold (commonly micro ohm level).

Protection function test:

Test the precision of action values and timing for protection functions such as overload, short circuit, and ground faultto ensure utmost safety.

Verify the settings andfunctionality of the intelligent release device, ensuring optimal performance.

 

Packaging & Shipping

Outer packaging:

Robust wooden boxes are typically utilized to bestow ample mechanical strength and durability.

Wooden crates are particularly suitable for large circuit breakers or for international transportation needs.

Inner packaging:

Envelop the circuit breaker with protective buffer materials such as foam padding, bubble wrap or pearl cotton to safeguard against vibrations and impacts.

For bulkier circuit breakers, the packaging box might feature a layered design. Accessories, including manuals, tools, and spare parts, are strategically placed on the upper layer for convenience.
