Product Description

AIR CIRCUIT BREAKER

MTW1-2000, MTW1-3200, MTW1-4000, MTW1-6300, MTW1-7500

The MTW1 series intelligent breaker is engineered for seamless operation in AC 50Hz distribution networks, catering to rated voltages of 400V and 690V, with a robust rated current range between 400Aand7500A. It is designed for efficient electric energy distribution and to safeguard circuits and power equipment from the adverse effects of overload, under-voltage, short circuit and single-phase earth faults etc. Equipped with state-of-the-art intelligent protection features and precise selective protection, the breaker significantly boosts the reliability of power supply and mitigates the risk of

inadvertent power outages.This circuit breaker exhibits an impressive impulse withstand voltage capacity of8000V at elevations reaching up to 2000 meters (with adaptability for varying altitudes, peaking at 12000V).

Our product is fully compliant with the GB14048.2 standard for low-voltage switchgear and controlling equipment, specifically tailored for low-voltage circuit breakers, and adheres to IEC60947-2 standards for low-voltage switchgear and controlling equipment, particularly the second part focused on low-voltage circuit breakers.

Installation Instructions

- Installed inside the panel

Fixed Type Installation:

The circuit breaker is directly and securely anchored to the distribution cabinet or installation board and remains immobile.

Perfectly suited for environments where frequent replacement or maintenance isn't necessary.

Effortless installation and cost-effective.

Drawout Type Installation:

The circuit breaker is mounted on a withdrawable frame, allowing for convenient maintenance, testing, and replacement.

Ideal for scenarios that demand frequent operation or maintenance.

Although installation is intricate and involves higher costs, it provides enhanced adaptability.

Plug-in Type Installation:

The circuit breaker seamlessly connects to the busbar via plug-in connection, allowing for swift installation and rapid replacement.

Best suited for situations requiring prompt replacement.

-Secondary Wiring Method

1 and 2: Connect to the intelligent controller
27 and 28:Link to the undervoltage coil
29 and 30: Attach to the shunt coil
31 and 32:Connect to closed coils
34 and 35: Integrate with the energy storage motor

Product testing

Mechanical operation test:

Assess the seamless and flawless mechanical operation of the circuit breaker to ensure it is flexible and reliable.

Thoroughly test the operation functionalities including closing, opening, and energy storage.

Electrical performance testing:

Insulation resistance test: Utilize a high-precision megohmmeter to gauge the insulation resistance of both main and auxiliary circuits, ensuring they adhere to the stringent standard requirements (generally ≥ 1M Ω).

Power frequency withstand voltage test: Administer rated power frequency voltage (e.g., 2500V for 1 minute) to the principal circuit and auxiliary circuit to evaluate their robust insulation performance.

Contact resistance test: Precisely measure the contact resistance on the main contact to certify it remains below the predetermined value, typically at micro ohm levels.

Protection function test:

Evaluate the action thresholds and timing of vital protection functions, including overload, short circuit, and ground fault.

Confirm the settings andfunctionality of the advanced intelligent release device.

 

Packaging & Shipping

Outer Packaging: The Ultimate Armor for Your Product

Designed with Strength in Mind Robust Wooden Boxes are typically employed to offer exceptional mechanical strength.

Wooden crates, ideal for large circuit breakers or international transit, ensure safety and security.

Inner Packaging: A Cushion of Care

The circuit breaker is carefully wrapped with protective buffer materials such as foam pads, bubble film or pearl cotton , effectively guarding against vibrations and collisions.

For larger circuit breakers, the packaging box may feature a thoughtful layered design, with essential accessories (such as manuals, tools, and spare parts) conveniently placed on the upper layer, ensuring easy access and organization.

Our production line is dedicated to maintaining the highest standards of quality and efficiency.
