When overload occurs during motor operation, the circuit breaker will act in time according to the preset overload curve to cut off the power supply and prevent the motor from being overloaded for a long time and damaged by heat; in case of a short-circuit fault, it can instantly trip the circuit breaker to avoid the short-circuit current from causing serious damage to the motor and the line; if there is a phase failure, the circuit breaker can quickly detect it and cut off the circuit, preventing the motor from being burnt due to the phase failure operation, and providing all-around protection for motor safety and reducing the chances of motor failure. It protects the motor in all aspects, reduces the chance of motor failure, and lowers the maintenance cost and downtime.
Reliable manual operation design: adopting manual operation mechanism, easy and intuitive operation. Users can easily perform closing and breaking operations through the handle, and the position of the handle clearly indicates the working status of the circuit breaker (closing, breaking or fault tripping), which is convenient for the operator to quickly understand the on-off situation of the circuit. This kind of manual operation is very practical in some occasions that require manual control of motor starting and stopping, and it also increases the reliability and flexibility of the operation, ensures that the power can be cut off in time in emergencies, and protects the safety of personnel and equipment.
Durable quality and structure: the shell is made of high-strength, high-temperature-resistant and flame-retardant materials, which can effectively resist the adverse factors such as high temperature, humidity, dust and mechanical shock in the motor operating environment, ensuring the safe and stable operation of the internal components of the circuit breaker. The internal contacts and release mechanism are carefully designed and optimised, using high-quality conductive and wear-resistant materials to ensure good contact, sensitive and reliable action during frequent opening and closing operations, reducing contact wear and the possibility of malfunction, improving the service life and reliability of the circuit breaker, and providing a solid guarantee for long-term stable motor protection.
3. Product use scene
Industrial manufacturing field: In the production lines of various factories, such as machining, automobile manufacturing, chemical production and other industries, a large number of motors are used to drive a variety of production equipment, such as machine tools, conveyor belts, fans, pumps, etc. GV2ME10C - 08C Manual Motor Circuit Breaker can be reasonably configured according to the power and operating characteristics of different motors to provide reliable protection for the motor. When a motor in the production line is overloaded, short-circuited or phase failure, the circuit breaker can quickly cut off the power supply of the motor to avoid the expansion of the fault affecting the operation of the whole production line, to protect the continuity and stability of production, to improve the production efficiency, and to reduce the economic losses due to the failure of the motor.
Commercial and civil facilities: In commercial places, such as shopping malls, hotels, office buildings and other HVAC systems, the motors of air-conditioning units, fresh air units, exhaust fans and other equipment need to be effectively protected.

The GV2ME10C - 08C circuit breaker is able to adapt to these environmental conditions by effectively protecting motors and equipment in the agricultural and farming industries, ensuring the smooth progress of agricultural production and farming activities, reducing the impact of motor failures on production, and increasing the economic benefits of the agricultural and farming industries.
4. Product use instructions
Preparation before installation:
Check the appearance of the circuit breaker for defects such as breakage, deformation, contact oxidation, shell cracks, etc. If there are any problems, contact the supplier for replacement in time to ensure that the quality of the GV2ME10C - 08C circuit breaker in use is intact and undamaged.
According to the rated current of the motor to be protected, select the suitable current setting value within the range of 0.1A - 32A, and use the appropriate tools (such as screwdriver) to adjust the current adjustment knob of the circuit breaker to ensure that the setting value is accurate. At the same time, prepare suitable installation tools, such as screwdrivers, wrenches, wire strippers, etc., to ensure the accuracy and applicability of the tools, so as to avoid damage to the circuit breaker during installation.
Installation and Connection:
Install the GV2ME10C - 08C circuit breaker on the rail of the motor control box or distribution cabinet, make sure it is firmly installed without looseness. Correctly connect the power and motor wires in accordance with the wiring specifications of the electrical system. Normally, connect the power cord to the input terminal of the circuit breaker (marked with ‘LINE’ or similar marking) and the motor cord to the output terminal (marked with ‘LOAD’ or similar marking), paying attention to the correctness and firmness of the wiring to avoid the situation of connecting the wrong wire or false connection The motor wires are connected to the output terminal (labelled ‘LOAD’ or similar). After the wiring is completed, use a screwdriver to tighten the screws on the terminals to ensure that the wires are in close contact with the terminals and to prevent heat, fire or malfunction due to poor contact.
Debugging and Testing:
After completing the installation and wiring, close the circuit breaker and start the motor to check whether it can work normally. Observe whether the starting process of the motor is smooth, with or without abnormal sound, vibration or smoke. At the same time, use professional electrical test instruments, such as clamp-on ammeter, to measure the operating current of the motor to ensure that the current value is within the normal range, and the circuit breaker does not appear to be in error or inoperative. You can test whether the overload protection function of the circuit breaker is sensitive and reliable by gradually increasing the load of the motor and simulating the overload situation; you can also artificially create a short-circuit fault (under the guidance of professionals and ensure safety) to check whether the short-circuit protection function is normal; for the missing-phase protection function, you can disconnect one phase of the power supply in turn during the motor operation to observe whether the circuit breaker can trip in time. If any problem is found, the wiring, current setting value and internal structure of the circuit breaker should be checked in time and adjusted and repaired accordingly.
Precautions for use:
Regularly check and maintain the circuit breaker to see if there is any abnormality in its appearance, such as heat, smoke, odour and discolouration of the shell. At the same time, check the wear of the contacts, if the contacts are found to be severely worn or ablated, the contacts or the whole circuit breaker should be replaced in time to ensure its normal opening and closing performance and protection function. It is generally recommended to carry out a comprehensive inspection and maintenance every certain period of time (e.g. half a year or one year), and the specific time interval can be determined according to the actual use environment and frequency.
