Product Description

Product Description

AIR CIRCUIT BREAKER

MT/MVS

ACB (Air Circuit Breaker) is a high-performance low-voltage circuit breaker, featuring exemplary models such as MT/NT and MVS series, accommodating rated currents ranging from 630A to 6300A, and boasting a remarkable breaking capacity reaching up to 150kA, making it eminently suitable for industrial, commercial, and energy distribution systems.

Core features:
Intelligence: Equipped with Micrologic release, offering advanced real-time monitoring (current, voltage, fault recording) and remote control capabilities, seamlessly integrated with the EcoStruxure platform.

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

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

Flexible Expansion:Expandable with communication modules (Modbus, Ethernet) and auxiliary contacts for tailored functionality.

Perfect for environments such as data centers, factories, and large buildings, celebrated for ensuring high security, efficient digital management, and reduced energy consumption, while adhering to IEC/GB standards.

 

Working principle:

This air circuit breaker continuously monitors the circuit's current in real-time via a current transformer, relaying the signal to the intelligent controller.

Upon detecting any abnormal current, the intelligent controller promptly disconnects the internal contacts and safely interrupts the circuit

Product testing

Mechanical operation test: A critical assessment to verify the seamless mechanical operations of our circuit breaker.

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

Evaluate the operation functions comprehensively, ensuring flawless performance in scenarios such as closing, opening, and energy storage.

Electrical performance testing: This stage is essential to confirm the electrical robustness of the breaker.

Insulation resistance test: Employ a megohmmeter to meticulously measure the insulation resistance of both main and auxiliary circuits, ensuring they conform to the stringent standard (typically ≥ 1M Ω).

Power frequency withstand voltage test: Subject the main circuit and auxiliary circuit to the rated power frequency voltage (such as 2500V/1min) to validate their superior insulation performance.

Contact resistance test: Accurately measure the contact resistance of the main contact, ensuring it remains below the specified benchmark (commonly within the micro ohm range).

Protection function test: A crucial evaluation to affirm the reliability and precision of protective mechanisms.

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

Verify the settings andfunctionality of the intelligent release device to ensure unparalleled protection and efficiency.
