Product Description

AIR CIRCUIT BREAKER

MT/MVS

ACB (Air Circuit Breaker) is a cutting-edge, high-performance low-voltage circuit breaker. Noteworthy models include MT/NT and MVS series, which accommodate rated currents ranging from 630A to an impressive 6300A, boasting a substantial breaking capacity of up to 150kA, making them idealfor use in sophisticated industrial, commercial, and energy distribution systems, offering unparalleled protection and efficiency.

Core Features that Set Us Apart:
Intelligence: Incorporates advanced Micrologic release technology, facilitating real-time monitoring (current, voltage, fault recording) alongside remote control capabilities, seamlessly integrating with the EcoStruxure platform.

High Reliability: Features a robust modular design, offering optional electronic or thermal magnetic protection, ensuring a lifespan of tens of thousands of operations.

Comprehensive Protection: Delivers superior overload, short circuit, and ground fault protection, with support for selective coordination to enhance system resilience.

Flexible Expansion:Easily accommodates communication modules (Modbus, Ethernet) and auxiliary contacts, tailoring to your specific needs.

Perfectly suited for environments such as data centers, factories, and expansive buildings, renowned for exceptional security, cutting-edge digital management, and reduced energy consumption, all conforming to strict IEC/GB standards.

 

Working Principle Explained:

The air circuit breaker diligently monitors the circuit's current in real-time using a highly responsive current transformer. It transmits the current signal directly to the intelligent controller,enhancing system oversight.

Upon detecting any irregular current flow,the intelligent controller promptly acts to disconnect the contacts within the circuit breaker, effectively severing the circuit to prevent damage.

You can simplify your installation process as there's no need to allocate space for the front connection. Thanks to the design of our terminals, the depth of the circuit breaker remains unaffected, offering you a compact solution.
· Whether you're working with a horizontal or vertical busbar, our innovative design allows for effortless adaptability. Just rotate the connection terminal by 90 degrees to achieve the desired configuration.

Product testing

1. Mechanical Operation Test:

Ensure that the mechanical operation of the Premium ACb Switch Circuit Breaker is evaluated meticulously. It is essential to verify that the operation is flexible and reliablefor seamless performance.

Rigorous testing of operational functions is conducted, including closing, opening, and energy storage, ensuring each function is flawless.

2. Electrical Performance Testing:

Insulation Resistance Test: Employ a precision megohmmeter to measure the insulation resistance of main and auxiliary circuits, ensuring adherence to standards (typically ≥ 1M Ω), thereby guaranteeing superior safety.

Power Frequency Withstand Voltage Test: Administer rated power frequency voltage (for example, 2500V/1min) to both main and auxiliary circuits to rigorously assess insulation performance.

Contact Resistance Test: Precisely measure the contact resistance of the main contact, ensuring it remains below the prescribed value, typically at the micro ohm level, for optimal functionality.

3. Protection Function Test:

Evaluate the precise action values and timing of critical protection functions, including overload, short circuit, and ground fault, ensuring robustness.

Confirm the settings and functionality of the intelligent release device, reinforcing its trustworthiness and efficiency.

 

Packaging & Shipping

Outer packaging:

Robust wooden crates are typically employed for providing exceptional mechanical strength.

Sturdy wooden crates are ideal for accommodating large circuit breakers or for international transportation requirements.

Inner packaging:

Envelop the circuit breaker with protective cushioning materials such as foam padding, bubble wrap or pearl cotton to effectively guard against vibrations and impacts.

For larger circuit breakers, the packaging can incorporate a multi-layered design, with essential accessories (such as manuals, tools, and spare parts) carefully organized on the upper layer.

Domestic transportation
If a specific freight forwarder is designated within China, we efficiently manage product delivery to the specified location using road transportation or domestic express services once production is finalized.

International transport

When shipments are minimal in quantity and time-sensitive, needing overseas delivery to a specified international location, the top three global express delivery services are selected for expedited transportation:
DHL, FEDEX, UPS

Sea freight/air freight
For large-scale shipments where time sensitivity is reduced, sea freight is the optimal choice. We collaborate with a reliable freight company, which arranges trucks to collect and transport goods to the designated port for warehousing,culminating in sea delivery to the customer's specified port. Customers are required to collect goods using a bill of lading.
