The UTPCH46RDY is an automatic six-phase motor starter. This type of motor starter is a convenient, cost-effective, and reliable solution for industrial motor control systems and is widely used in industrial settings such as manufacturing plants, processing facilities, and machine shops. The UTPCH46RDY is a fully enclosed starter that provides overload protection and thermal trip protection. It features an adjustable automatic or manual start mode, an adjustable current overload setting, a non-volatile trip history, and adjustable current ratings.

The UTPCH46RDY application field includes many industrial applications such as metal processing, raw materials handling, motorized devices for the food industry, plastic injection and extrusion, paper and pulp handling, and general-purpose motors. These all require reliable motor starting and overload protection.

The UTPCH46RDY working principle is based on a combination of electrical and electromechanical components. The electrical components consist of a main power contactor and a motor-start contactor, both of which are connected to a control circuit. The control circuit is connected to a set of adjustable current overloads, which act as protective devices. The electromechanical components consist of a spring-loaded starter handle and a trip lever which are both used to manually start and stop the motor.

The two contactors in the UTPCH46RDY are connected in series across the mains, and the control circuit is connected in series between them. When the machine is turned on, current passes through the contactors and the control circuit and is monitored by the current overloads. If the current exceeds the level set on the overloads, the protective devices will trip and the motor will be shut down.

The UTPCH46RDY working principle also includes the thermal trip feature. This feature is designed to protect the motor from being damaged due to excessive heat generated during operation. The thermal trip mechanism is triggered by a heat-sensitive element which is connected to the control circuit. Once the operating temperature reaches a certain level, the element will open the circuit and cut off the power.

The UTPCH46RDY is a versatile and reliable motor starter for industrial settings and is a cost-effective solution for overload protection and thermal trip protection. It is easy to install, use, and maintain. The adjustable parameters and adjustable current ratings make it a flexible and customizable solution for industrial motor control needs.
