Product Description

AIR CIRCUIT BREAKER

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

The MTW1 series intelligent breaker is perfectly designed for the AC 50Hz distribution network, with a rated voltage of 400V and 690V, offering a rated current range between 400A~7500A. This advanced solution efficiently distributes electric energy and provides robust protection for circuits and power equipment against the risks of overload, under-voltage, short circuit and single-phase earth faults. Equipped with an intelligent protection feature and precise selective protection, it significantly enhances power supply reliability and prevents

unnecessary power interruptions.The circuit breaker boasts an impressive impulse withstand voltage of8000V at an altitude of 2000 meters (adjustments made for varying altitudes, with a maximum not surpassing 12000V).

This remarkable product complies with the standards of GB14048.2 for low-voltage switchgear and control equipment, specifically targeting low-voltage circuit breakers and adheres to IEC60947-2 for low-voltage switchgear and control equipment, part two: low-voltage circuit breaker.

Perfect for environments where quick swaps are essential.

-Secondary Wiring Method

1 and 2: Interface the intelligent controller
27 and 28:Link the undervoltage coil
29 and 30: Integrate the shunt coil
31 and 32:Engage closed coils
34 and 35: Connect the energy-storing motor

Product testing

Comprehensive Mechanical Operation Test:

Scrutinize the mechanical operation of the circuit breaker to ensure it is supremely flexible and unwaveringly reliable.Test the seamless operation functions such as

closing ,opening , and the precision ofenergy storage. Electrical Performance Testing Excellence:Conduct an insulation resistance test: Employ a megohmmeter to measure the insulation resistance of both main and auxiliary circuits, guaranteeing they surpass standard requirements (typically ≥ 1M Ω).

Power Frequency Withstand Voltage Test: Administer rated power frequency voltage (e.g., 2500V/1min) to both the main and auxiliary circuits, assessing the robustness of insulation performance.

Contact Resistance Test: Meticulously gauge the contact resistance of the primary contact to confirm it is beneath the established threshold (commonly at a micro ohm level).

Protection Function Test Mastery:

Evaluate the action values and timing of protection functions such as

overload, short circuit

, and ground fault. Assure the calibrationand operability

of the cutting-edge intelligent release device.

 

Packaging & Shipping

Outer Packaging: A Fortress of Protection

Robust and Resilient wooden boxes are strategically selected to offer unparalleled mechanical strength.

Wooden crates are ideal for accommodating large circuit breakers, perfectly tailored for international transportation.

Inner Packaging: Cushioned Care

Envelop the circuit breaker in layers of protective materials such as foam pads, bubble film or pearl cotton to mitigate the risks of vibration and collision.

For larger circuit breakers, the packaging box can feature a sophisticated layered design, with essential accessories like manuals, tools, and spare parts) thoughtfully placed on the upper layer to enhance accessibility.
