Description:
The MTW1 series smart circuit breaker is designed for AC distribution networks operating at 50Hz, with rated voltages of 400V and 690V, and a rated current range from 400A to 7500A. It serves to distribute electrical power and protect circuits and connected equipment from faults such as overload, undervoltage, short circuit, and single-phase ground faults. Equipped with intelligent protection and precise selective tripping capabilities, this breaker enhances power supply reliability and helps prevent unplanned outages. At an altitude of 2000 meters, its impulse withstand voltage is rated at 8000V (adjustable according to altitude-based standards, with a maximum not exceeding 12000V).
This product meets the requirements of both GB14048.2 "Low-voltage switchgear and controlgear – Low-voltage circuit breakers" and IEC 60947-2 "Low-voltage switchgear and controlgear – Part 2: Circuit-breakers."

2.The primary function of an air circuit breaker (ACB) is as a reliable switch and protection device for the main power distribution system. It effectively protects circuits and equipment in industrial plants, commercial buildings, and large facilities from potential damage caused by overcurrent and short-circuit faults. By instantly interrupting fault current, it ensures the safety of the entire system, prevents electrical fires, and safeguards downstream assets and personnel.

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 of energy 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.

Fixed Type Installation
The circuit breaker is permanently mounted onto the distribution cabinet or panel and remains fixed in position.
This type is suited for applications where maintenance or replacement is seldom required.
It offers simple installation and economical operation.
Drawout Type Installation
The circuit breaker is installed on a removable chassis, allowing easy access for testing, maintenance, and replacement.
It is designed for systems that undergo frequent operation or regular servicing.
Though more complex and costly to install, this type provides greater flexibility and convenience.
Plug-in Type Installation
The circuit breaker connects directly to the busbar through a plug-in interface, enabling quick installation and replacement.
This design is ideal for applications where rapid unit interchange is necessary.
