Product Description

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 of 630A~6300A, with a formidable breaking capacity of up to 150kA, making it exceptionally suitable for industrial, commercial, and energy distribution systems.

Core features:
Intelligence: Equipped with a state-of-the-art Micrologic release, it supports advanced real-time monitoring (current, voltage, fault recording) and offers seamless remote control, fully compatible with the innovative EcoStruxure platform.

High reliability: Features a robust modular design, offering optional electronic/thermal magnetic protection, with an impressive lifespan rated for tens of thousands of operations.

Comprehensive protection: Ensures reliable overload, short circuit, and ground fault protection, with support for selective coordination.

Flexible Expansion:Can be enhanced with communication modules (Modbus, Ethernet) and auxiliary contacts for diverse applications.

Ideal for data centers, manufacturing facilities, and large-scale buildings, distinguished for its high security, digital management, and efficient energy conservation, all while adhering to IEC/GB standards.

 

Working principle:

The air circuit breaker consistently monitors the electrical current via a high-precision current transformer, transmitting the data to the intelligent controller.

When the intelligent controller detects any abnormal current, it promptly disconnects the internal contacts of the circuit breaker to safely cut off the circuit, ensuring optimal protection.

Product testing

Mechanical Operation Test: Guaranteeing Uninterrupted and Smooth Functionality

Meticulously examine the mechanical operation of the circuit breaker to ensure it is exceptionally flexible as well as remarkably reliable.

Conduct a comprehensive assessment of operational functions, including: secure closing, efficient opening, and effective energy storage.

Electrical Performance Testing: Upholding a Pledge to Safety

Insulation Resistance Test: Utilize a precision megohmmeter to evaluate the insulation resistance of both main and auxiliary circuits, ensuring they align seamlessly with industry standards (commonly ≥ 1M Ω).

Power Frequency Withstand Voltage Test: Administer the rated power frequency voltage (such as 2500V for a full minute) to the main and auxiliary circuits to thoroughly assess their extraordinary insulation capabilities.

Contact Resistance Test: Precisely measure the contact resistance of the primary contact to ensure it steadfastly remains below the defined threshold (typically maintained at the micro-ohm level).

Protection Function Test: Your Equipment's Unsurpassed Safeguard

Carefully evaluate the action values and precise timing of protection functions, with a keen focus on overload, short circuit, as well as ground fault.

Diligently verify the optimal settings andenhanced functionality of the intelligent release device, guaranteeing peak performance and supreme reliability.
