2P18U3H/24, also known as a double-ended starter, is a type of starter used to control the motors used in industrial and domestic applications. It is a device used to start and stop electric motors, and it works in conjunction with circuit breakers and relays. The device is a combination of a contactor and an overload relay that is used to automatically control the motor.

2P18U3H/24 comes in various sizes and is generally used in industrial applications where the motor needs to be quickly turned on and off. It can also be used for protection against overloads and short circuit conditions in motors. The starter contains two main components, which are the contacts and the overload relay. The contacts act as the on/off switch for the motor; when they are closed, power is supplied to the motor and when they are open, the motor is turned off. The overload relay is responsible for protecting the motor from overloads by sensing the current and shutting the motor off if it exceeds a predetermined limit.

2P18U3H/24 can be used in a variety of applications, including elevators, pumps, fans, blowers, compressors, and various manufacturing processes. The starter is suitable for applications where motors need to be started quickly, and where quick response and high starting torque are required. It is also used in applications where it is important to protect the motor from overloads and where frequent starts and stops are required.

The working principle of 2P18U3H/24 is fairly straightforward. When the on/off switch is actuated, it allows for current to travel through the contacts, enabling power to reach the motor. When the switch is released, the power is cut off and the motor will not turn on. The overload relay senses the current within the motor and if it exceeds the predetermined limit, it will shut off the motor, even when the switch is in the on position.

2P18U3H/24 is a versatile device, suitable for numerous applications. It can be used to control the start and stop of the motor, and can be used to protect the motor from overloads and short circuit conditions. With its quick response and high starting torque, it is the ideal choice for numerous industrial and domestic applications.
