Product Description

Product Description

AIR CIRCUIT BREAKER

MT/MVS

ACB (Air Circuit Breaker) is an exemplar of high-performance, low-voltage excellence circuit breakers, spotlighting leading models like MT/NT and MVS series, accommodating a spectrum of rated currents from 630A up to a robust 6300A, boasting a formidable breaking capacity reaching 150kA, making it an ideal choice for industrial, commercial, and sophisticated energy distribution systems.

Core features:
Intelligence: Equipped with the advanced Micrologic release, it enables precise real-time monitoring (current, voltage, fault recording) and offers remote operation, seamlessly compatible with the EcoStruxure platform.

High reliability: With its modular design, offering optional electronic or thermal magnetic protection, it guarantees a lifespan extending to tens of thousands of operations.

Comprehensive protection: This product ensures robust overload, short circuit, and ground fault protection, while supporting selective coordination for optimal safety.

Flexible Expansion:Easily upgradeable with communication modules (Modbus, Ethernet) and additional auxiliary contacts for enhanced functionality.

Perfectly suited for environments like data centers, manufacturing plants, and expansive buildings, it is celebrated for its superior security, digital management capabilities, and energy-efficient operation, meeting the stringent IEC/GB standards.

 

Working principle:

The air circuit breaker meticulously oversees the circuit's current in real-time utilizing a current transformer, transmitting the current signal directly to the intelligent controller.

Upon identifying any abnormal current, the intelligent controller swiftly disconnects the internal contacts of the circuit breaker to efficiently cut off the circuit

Product testing

Mechanical operation test: Ensuring seamless and flawless performance.

Check whether the mechanical operation of the circuit breaker is designed to be flexible and reliable.

Test the operation functions with precision, including closing, opening, and energy storage.

Electrical performance testing: An assurance of electrical integrity and safety.

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

Power frequency withstand voltage test: Apply rated power frequency voltage (e.g., 2500V/1min) to the main and auxiliary circuits to confirm superior insulation performance.

Contact resistance test: Accurately measure the contact resistance of the main contact to ensure it remains below specified thresholds (usually in the micro ohm range).

Protection function test: A testament to our commitment to safety and performance.

Test the action values and timing precision of protection functions like overload, short circuit, and ground fault.

Verify the meticulous settings andfunctionality of our cutting-edge intelligent release device.
