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 ranging from an impressive 630A up to a remarkable 6300A, and boasting a substantial breaking capacity of up to 150kA, making it the perfect choice for industrial, commercial, and energy distribution systems, ensuring unparalleled safety and efficiency.

Core features:
Intelligence: Equipped with a sophisticated Micrologic release system, it supports real-time monitoring features such as (current, voltage, and fault recording) and offers seamless remote control, fully integrated with the advanced EcoStruxure platform.

High reliability: Thanks to its innovative modular design and choice of electronic or thermal magnetic protection, this breaker promises a lifespan spanning tens of thousands of reliable operations.

Comprehensive protection: Delivers robust defenses against overload, short circuit, and ground fault incidents, while supporting selective coordination for optimal safety.

Flexible Expansion:With options for additional communication modules such as (Modbus and Ethernet), along with auxiliary contacts, customization is made simple.

Perfectly suited for demanding environments like data centers, factories, and expansive buildings, it is renowned for its high-security features, digital management capabilities, and energy-efficient performance, all in strict adherence to IEC/GB standards.

 

Working principle:

This air circuit breaker diligently monitors the circuit's current in real-time through its integrated current transformer, transmitting precise current signals to its intelligent controller.

Upon detecting any abnormal current flow, the intelligent controller swiftly acts to disconnect the internal contacts, effectively cutting off the circuit

· For the MTN and MTH models ranging from 800A to 6300A (excluding 4000A), you'll find consistency across the connection terminals, ensuring seamless integration.;
No additional space is required for front connections, as the terminals maintain the original circuit breaker depth,
· Whether connecting to a horizontal or vertical busbar, effortlessly rotate the connection terminal a precise 90 degrees for perfect alignment.

Product testing

Mechanical operation test:

Carefully inspect the mechanical operation of the circuit breaker to ascertain whether it is flexible and reliable.

Thoroughly test the operational functionalities, including closing, opening, and energy storage.

Electrical performance testing:

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

Power frequency withstand voltage test: Subject the main and auxiliary circuits to the rated power frequency voltage (such as 2500V/1min) to rigorously evaluate the insulation integrity.

Contact resistance test: Precisely measure the contact resistance of the main contact to ensure it remains below the prescribed threshold (commonly at the micro ohm level).

Protection function test:

Meticulously test the action thresholds and timing of protection functions, including overload, short circuit, and ground fault.

Confirm and verify the settings andfunctionality of the intelligent release device, ensuring precision and reliability.

 

Packaging & Shipping

Outer packaging:

We prioritize solid and robust protection for every shipment. Premium wooden boxes are typically employed to ensure ample mechanical strength.

A sturdy wooden crate is ideal for large circuit breakers or when shipping internationally.

Inner packaging:

To guard against vibration and impact, the circuit breaker is enveloped with cushioning materials like foam pads, bubble film or pearl cotton. This meticulous packaging strategy ensures optimal protection.

For larger circuit breakers, a layered design is utilized within the packaging box, allowing accessories (such as manuals, tools, spare parts) to be conveniently placed on the upper level.
