Product Description

AIR CIRCUIT BREAKER

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

The MTW1 series intelligent breaker is specially crafted for distribution networks operating at AC 50Hz with a rated voltage of either 400V or 690V. It boasts a rated current capacity ranging from 400Ato7500A. Its purpose is to efficiently distribute electric energy while safeguarding circuits and power equipment from the potential damages of overload, under-voltage, short circuit and single-phase earth faults . Equipped with advanced intelligent protection features and precise selective protection capabilities, this breaker significantly boosts the reliability of power supply and prevents

undesired power interruptions.The circuit breaker boasts an impressive impulse withstand voltage of8000V at altitudes of up to 2000 meters (with adjustments made according to different altitude standards, not exceeding 12000V).

This innovative product complies with the stringent standards of GB14048.2 for low-voltage switchgear and control equipment, as well as the regulations of the low-voltage circuit breaker, IEC60947-2 for low-voltage switchgear and control equipment, specifically outlined in the second segment: low-voltage circuit breakers.

Installation Instructions

-Installed inside the panel

Fixed Type Installation:

The circuit breaker is firmly secured directly on the distribution cabinet or installation board and is immovable.

Ideal for environments where frequent replacement or maintenance is unnecessary.

Effortless installation and economical cost.

Drawout Type Installation:

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

Perfect for settings that require regular operation or routine maintenance.

Installation is intricate and incurs a higher cost, yet it provides enhanced adaptability.

Plug-in Type Installation:

The circuit breaker connects seamlessly to the busbar via a plug-in method, facilitating effortless installation and swift replacement.

Ideal for scenarios that demand rapid replacement.

-Secondary Wiring Method

1 and 2: Establish a connection with 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 the energy storage motor

Product testing

Meticulous Mechanical Operation Test:

Meticulously examine whether the mechanical operation of the circuit breaker is seamlessly flexible and unfailingly reliable.

Thoroughly test operational functions including precise closing, accurate opening, and efficient energy storage.

In-Depth Electrical Performance Testing:

Rigorous Insulation Resistance Test: Employ a precise megohmmeter to measure the insulation resistance across the main and auxiliary circuits, ensuring compliance with standards (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 thoroughly assess insulation performance.

Contact Resistance Evaluation: Accurately measure the contact resistance of the main contact to ensure it remains below the specified threshold (commonly at a micro ohm level).

Advanced Protection Function Testing:

Assess the critical action values and timing of protection functions such as overload, short circuit, and ground fault.

Verify the impeccable settings androbust functionality of the sophisticated intelligent release device.

 

Packaging & Shipping

Outer packaging:

To ensure unparalleled protection and security, we employ robust wooden boxes that are meticulously crafted to deliver exceptional mechanical strength.

These wooden crates are designed to accommodate large circuit breakers or endure international transportation with ease.

Inner packaging:

Safeguard your investment by wrapping the circuit breaker with premium buffer materials like foam pads, bubble film or pearl cotton to effectively prevent any vibration and collision during transit.

For larger circuit breakers, our packaging solutions may incorporate a smart layered design, where accessories, including manuals, tools, and spare partsare conveniently placed on the upper layer for easy access.
