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 breaking capacity of up to 150kA, suitable for industrial, commercial, and energy distribution systems.

Core features:
Intelligence: Built in Micrologic release, supports real-time monitoring (current, voltage, fault recording) and remote control, compatible with EcoStruxure platform.

High reliability: modular design, optional electronic/thermal magnetic protection, with a lifespan of tens of thousands of operations.

Comprehensive protection: Provides overload, short circuit, and ground fault protection, and supports selective coordination.

Flexible Expansion:Communication modules (Modbus, Ethernet) and auxiliary contacts can be installed.

Suitable for scenarios such as data centers, factories, and large buildings, known for high security, digital management, and low energy consumption, in compliance with IEC/GB standards.

 

Working principle:

The air circuit breaker monitors the current in the circuit in real-time through a current transformer. And transmit the current signal to the intelligent controller.

After the intelligent controller detects the abnormal current, it will disconnect the contacts inside the circuit breaker and cut off the circuit

Installation Instructions

·MTN, MTH800A to 6300A (except 4000A) offer uniform connection terminals for seamless integration,;
No additional front clearance required as terminals maintain the circuit breaker's compact depth;
·Effortlessly connect to either horizontal or vertical busbars by simply rotating the connection terminal a precise 90 degrees.

Product testing

Mechanical Operation Test:

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

Ensure seamless performance by testing the operation functions such as closing, opening, and energy storage.

Electrical Performance Testing: Elevate Safety and Reliability

Insulation Resistance Test: With meticulous care, use a megohmmeter to measure the insulation resistance of both main and auxiliary circuits, ensuring they meet the rigorous standard (typically ≥ 1M Ω).

Power Frequency Withstand Voltage Test: Apply the rated power frequency voltage (such as 2500V/1min) to both the main circuit and auxiliary circuit to rigorously assess their insulation performance.

Contact Resistance Test: Precisely measure the contact resistance of the main contact, ensuring it remains below the specified threshold (commonly at the micro ohm level).

Protection Function Test: Safeguard with Precision

Diligently test the action values and response times of crucial protection functions such as overload, short circuit, and ground fault.

Verify the settings andfunctionality of the intelligent release device, ensuring peak performance and reliability.

 

Packaging & Shipping

Outer packaging:

We employ robust wooden boxes to ensure exceptional mechanical strength and protection.

These crates are ideal for accommodating large circuit breakers and are perfect for international journeys.

Inner packaging:

The circuit breaker is carefully enveloped in cushioning materials such as foam pads, bubble film or pearl cotton to safeguard against vibrations and impacts.

For sizable circuit breakers, we incorporate a thoughtful layered design within the packaging box. This allows accessories (such as manuals, tools, and spare parts) to be conveniently stored on the upper tier.

Domestic transportation
For local deliveries, should a specific freight forwarder in China be designated, we ensure the products reach the designated location via road transportation or domestic express services post-production.

International transport

In scenarios where shipments are limited and time-sensitive, requiring swift delivery to an international destination, we partner with premier international express providers like
DHL, FEDEX, or UPS

Sea freight/air freight
For large-scale shipments where timing is flexible, sea freight becomes our choice. We strategically select a reliable freight company, which coordinates truck pickups to transport goods to designated ports for warehousing.Subsequently, goods are shipped by sea to the client's specified port, where retrieval is facilitated with a bill of lading.
