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 a wide range of applications within industrial, commercial, and energy distribution systems, ensuring unparalleled performance and safety.

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

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

Comprehensive protection: Provides overload, short circuit, and ground fault protection, with the capability to support selective coordination to enhance safety.

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

Ideal for environments such as data centers, factories, and large buildings, renowned for delivering high security, efficient digital management, and reduced energy consumption, fully compliant with IEC/GB standards.

 

Working principle:

The air circuit breaker meticulously monitors the current in the circuit in real-time through a precise current transformer, relaying the current signal to the intelligent controller.

Upon detecting abnormal current, the intelligent controller promptly disconnects the contacts within the circuit breaker and efficiently cuts off the circuit to prevent damage and ensure safety

Product testing

Unwavering Mechanical Operation Test:

Conduct a meticulous inspection to ensure the mechanical operation of the circuit breaker is optimally flexible and steadfastly reliable.

Assess the seamless operation of functions including swift closing,precise opening,and efficient energy storage.

Comprehensive Electrical Performance Tests:

Insulation Resistance Excellence: Utilize a high-precision megohmmeter to measure insulation resistance of both main and auxiliary circuits, ensuring compliance with stringent standards (typically ≥ 1M Ω).

Power Frequency Withstand Voltage Verification: Subject the main and auxiliary circuits to rated frequency voltage (e.g., 2500V/1min) to affirm superior insulation performance.

Impeccable Contact Resistance Test: Measure the contact resistance of the main contacts, ensuring it remains within the specified micro ohm level for peak efficiency.

Robust Protection Function Tests:

Evaluate precision in the action values and timings of protection functions such as overload protection, short circuit interruption, and ground fault safeguarding.

Confirm the accuracy of settings andoperational functionality of the advanced intelligent release device.

 

Packaging & Shipping

Outer Packaging:

Robust and Durable wooden boxes are typically employed to ensure ample mechanical strength and protection.

A sturdy wooden crate is ideal for large circuit breakers or when shipping internationally.

Inner Packaging:

Encase the circuit breaker securely with cushioning materials such as foam pads, bubble wrap or pearl cotton to effectively mitigate vibrations and prevent collisions.

For large circuit breakers, consider a layered packaging approach, with accessories (such as manuals, essential tools, spare parts) organized on the top layer for easy access.
