GV2G445 is part of a series of motor starters mainly used for the control and protection of three-phase induction motor. This type of motor starter is equipped with many useful functions that make it suitable for multiple applications. In this article, we will discuss the different application fields and the working principle of the GV2G445.

Application Fields

The GV2G445 motor starter can be used in different industrial and commercial sectors, such as:

• Lighting systems
• Air conditioning systems
• Heating systems
• Air extraction systems
• Ventilation systems.

Due to its wide range of applications, the GV2G445 can be widely used in both industrial and residential settings.

Working Principle

The working principle of the GV2G445 motor starter involves the use of two components, a thermal overload relay and a motor starter. The thermal overload relay monitors the current in the motor, and when it reaches a certain level, it trips the motor starter, cutting off the current to the motor. This protects the motor from overload and prevents it from being damaged.

The GV2G445 motor starter also has a control switch, which allows the user to manually control the motor starter. This switch can be used to start the motor or to stop it, depending on the user’s needs.

The GV2G445 motor starter is also equipped with a thermal overload protection device, which is used to protect the motor from heat damage. This device monitors the motor for any sign of excessive heat, and if detected, it trips the motor starter, cutting off the power to the motor. This ensures that the motor is protected from thermal damage.

GV2G445 motor starters are also equipped with an under voltage protection, which monitors the voltage in the motor and trips the motor starter if the voltage drops below a certain level. This helps ensure that the motor is protected from low voltage, which can lead to damage.

The GV2G445 motor starter also features direct-on-line starting and soft-start/stop control. Direct-on-line starting allows the motor to be turned on without the need to adjust contacts or switches, while the soft-start/stop control reduces the wear and tear on the motor by gradually increasing or decreasing the speed of the motor.

The GV2G445 motor starter also features a two-speed motor option, which can be used to vary the speed of the motor depending on the requirements. This allows the motor to run at a slower speed for applications such as air conditioners or refrigerators and at a higher speed for applications such as pumps or plating plants.

The GV2G445 motor starter also has a variety of accessories, such as push buttons, contactors, and protective devices, which can be used to customise the motor starter for specific applications.

All of these features make the GV2G445 motor starter a very versatile and efficient option for any application requiring motor control. The wide range of features and accessories make it an ideal choice for industrial and commercial applications.
