Product Description

Product Description

AIR CIRCUIT BREAKER

MT/MVS

ACB (Air Circuit Breaker) is a high-performance low-voltage solution, offering impressive circuit protection with models such as MT/NT and MVS series. These breakers cater to rated currents ranging from 630A~6300A, boasting a powerful breaking capacity of up to 150kA. Ideal for industrial, commercialand energy distribution systems, they ensure unmatched safety and efficiency.

Core features:
Intelligence: Equipped with an advanced Micrologic release, it facilitates real-time monitoring (current, voltage, fault recording) along with remote control, seamlessly integrating with the EcoStruxure platform.

High Reliability: Its modular design, coupled with optional electronic and thermal magnetic protection, ensures a lifespan extending to tens of thousands of operations.

Comprehensive Protection: Ensures robust overload, short circuit, and ground fault protection, while supporting selective coordination.

Flexible Expansion:Incorporating communication modules (Modbus, Ethernet) and auxiliary contacts, it is easily adaptable to various needs.

Perfectly suited for environments like data centers, factories, and large buildings, it is renowned for high security, digital management, and eco-friendly energy consumption, conforming to IEC/GB standards.

 

Working Principle:

The air circuit breaker incessantly monitors the circuit's current via a current transformer, transmitting signals to the intelligent controller.

Upon recognizing abnormal current, the intelligent controller swiftly disconnects the internal contacts and safely interrupts the circuit

Product testing

Rigorous Mechanical Operation Evaluation:

Meticulously check whether the mechanical operation of the circuit breaker exhibits flexibility and reliabilityat its best.

Thoroughly test the operation functions, including closing, opening, and energy storage,ensuring seamless performance.

Electrical Performance Testing: Precision in Action

Insulation Resistance Test: Employ a megohmmeter to accurately measure the insulation resistance of both main and auxiliary circuits, ensuring compliance with the standard benchmarks (typically ≥ 1M Ω).

Power Frequency Withstand Voltage Test: Subject the main circuit and auxiliary circuit to rated power frequency voltage (e.g., 2500V/1min) to scrutinize insulation performance thoroughly.

Contact Resistance Test: Precisely measure the contact resistance of the main contact to ascertain it remains below the specified threshold (customarily at micro ohm level).

Comprehensive Protection Function Testing:

Conduct tests on the action values and response times of protection functions including overload, short circuit, and ground fault,guaranteeing optimal protection.

Diligently verify the settings andfunctionality of the intelligent release device, ensuring state-of-the-art protection.

 

Packaging & Shipping

Outer packaging:

Robust wooden boxes are typically utilized to ensure ample mechanical strength and durability.

A wooden crate is ideal for accommodating large circuit breakers or for international shipping needs.

Inner packaging:

Encase the circuit breaker with protective buffer materials such as foam pads, bubble wrap or pearl cotton to safeguard against vibrations and impacts.

For larger circuit breakers, the packaging box may feature a multi-layered design, with accessories (such as manuals, tools, and spare parts) strategically placed on the upper layer for easy access.

Domestic transportation
In case a designated freight forwarder is appointed in China, we will transport the products to the specified location utilizing road transportation or domestic express delivery services post-production completion.

International transport

For small quantities where time is critical, and delivery is required at an internationally designated destination, we partner with leading international express delivery companies like
DHL, FEDEX, and UPS for prompt and reliable service.

Sea freight/air freight
For larger shipments where time is more flexible, we opt for sea freight. We collaborate with a reputable freight company, which arranges for trucks to collect the goods and deliver them to the designated port for warehousing. Subsequently, the goods are transported by sea to the customer's specified port, where collection is made using a bill of lading.
