Product Description

Product Description

AIR CIRCUIT BREAKER

MT/MVS

ACB (Air Circuit Breaker) is an exceptionally high-performance low-voltage circuit breaker. Our distinguished product line includes the MT/NT and MVS series, each designed to handle rated currents ranging from 630A~6300Awith an impressive breaking capacity reaching up to 150kA.This makes it ideal for industrial and commercialapplications, as well as energy distribution systems.

Core features:
Intelligence: Equipped with an advanced Micrologic release, it facilitates real-time monitoring ofcurrent, voltage, and fault recordingsand supports remote control, seamlessly integrating with the EcoStruxure platform.

High reliability: Its innovative modular design allows for optional electronic or thermal magnetic protection, boasting a lifespan that extends to tens of thousands of operations.

Comprehensive protection: It offers robust protection against overload, short circuit, and ground faults, while supporting selective coordination for enhanced safety.

Flexible Expansion:Additional communication modules such asModbus and Ethernetare available, alongside auxiliary contacts, providing versatility and adaptability.

Perfectly suited for environments like data centers, factories, and large buildings, it is renowned for its high security, digital management capabilities, and low energy consumption, meeting all IEC/GB standards.

 

Working principle:

The air circuit breaker continuously monitors the current in the circuit through a current transformer, transmitting these signals to the intelligent controller.

Upon detecting any abnormal current,the intelligent controller swiftly disconnects the internal contacts of the circuit breaker to safely cut off the circuit, ensuring optimal protection.

Installation Instructions

· The MTN and MTH800A models, ranging from 800A to 6300A (excluding 4000A), boast the same connection terminals.;
Ingeniously designed, there's no need for additional space for front connections, as the terminals do not increase the circuit breaker's depth.
· Whether connecting to horizontal or vertical busbars, you can effortlessly turn the connection terminal 90 degrees, ensuring versatility and ease.

Product testing

Mechanical Operation Test - Confirming Robust Performance

Meticulously evaluate whether the mechanical workings of the Versatile ACb Switch Circuit Breaker are: flexible, offering seamless adaptability, and reliable, ensuring unwavering dependability.

Assess the operational functions, focusing on critical actions such as: closing, guaranteeing secure engagement,, opening, ensuring quick and efficient release,, and energy storage, providing sustained functionality.

Electrical Performance Testing - Upholding Safety and Standards

Insulation Resistance Test: Utilize a megohmmeter to precisely measure the insulation resistance across both main and auxiliary circuits, confirming they surpass the industry standards, typically ≥ 1M Ω.

Power Frequency Withstand Voltage Test: Administer the rated power frequency voltage, such as 2500V for 1 minute, to both main and auxiliary circuits, effectively evaluating the integrity of insulation performance.

Contact Resistance Test: Accurately measure the contact resistance of the primary contact, ensuring it remains below the prescribed threshold, typically at the micro ohm level, signifying optimal conductivity.

Protection Function Test - Safeguarding Your Home Continuously

Examine the operational values and timing of protection mechanisms like: overload protection, safeguarding against excess current, and ground fault detection, maintaining earth safety.

Authenticate the settings andfunctionality of the intelligent release device, ensuring it operates with precision and reliability.

 

Packaging & Shipping

Outer Packaging:

Robust wooden boxes are typically employed to ensure optimal mechanical strength.

Wooden crates are recommended for sizable circuit breakers or international shipping.

Inner Packaging:

Encase the circuit breaker with cushioning materials such as foam padding, bubble wrap or pearl cotton to mitigate vibration and impact.

For substantial circuit breakers, a layered packaging design might be employed, with accessories (including manuals, tools, spare parts) strategically placed on the top layer.
