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 Seamless Functionality

Meticulously inspect the mechanical operation of the circuit breaker to ensure it remains effortlessly flexible as well as consistently reliable.

Conduct comprehensive tests on all operational features, including: the closing mechanism, the opening mechanism, and energy storage capabilities.

Electrical Performance Testing: Our Pledge to Absolute Safety

Insulation Resistance Test: Utilize a state-of-the-art megohmmeter to assess the insulation resistance of both main and auxiliary circuits, ensuring unwavering compliance with industry benchmarks (typically ≥ 1M Ω).

Power Frequency Withstand Voltage Test: Apply the designated power frequency voltage (e.g., 2500V for a duration of 1 minute) to both main and auxiliary circuits to evaluate their superior insulation resilience.

Contact Resistance Test: Measure the contact resistance of the primary contact with precision, ensuring it remains well within the stringent specified threshold (generally at the micro-ohm level).

Protection Function Test: Vigilantly Guarding Your Equipment

Assess the action values and response times of protection functions, with particular attention to overload protection, short circuit intervention, as well as ground fault detection.

Carefully confirm the precision settings andadvanced functionality of the intelligent release device, ensuring it operates at peak performance.
