UTP6A60MVL is a device adaptable within power equipment control for a wide variety of thermal and hydraulic protection applications. Its main function is to measure or monitor the over-current, thermal overloading and control of the output, protect the motors from burn out. The UTP6A60MVL offers added protection and control in 3-phase motors. The advantage of using this device is that it contributes to extend motor life, improve output performance and reduce maintenance costs.

The UTP6A60MVL is designed with a wide range of setting options including adjustable current and adjustable time delay according to user\'s requirement. It also has built-in anti-impact and spike-resistant features and reset and bypass functions for convenience and reliability for users. The device is also designed with a universal plug and play connection for easy installation and commissioning.

In general, the UTP6A60MVL is used in the power supply of equipment, including switchgear, motor control, and transmission systems, to detect the over-current, over-voltage, over-load, short circuit and single-phase protection of AC voltage circuits and electronic equipment. In addition, this is suitable for most power control application including industrial, medical, domestic, and military machines. It is necessary to identify potential power problems before they cause damage to systems.

The working principle of UTP6A60MVL is quite simple and it defends from industrial current overloads. It ensures the motor will be not overloaded and the protection time might be different according to the user\'s requirements from 0 to 10 seconds. The two main parts of an UTP6A60MVL are the over-current sensing and overload protection method. This safety fuse has three components connected in series, a high-accuracy current transformer, an overload relay, and a star-timer. The whole unit will be connected to the AC supply to monitor the current passing through the motor. The current transformer (CT) will sense the current passing through the motor and will send the ac line voltage signal to the relay and timer.

When the relay senses an overload, it will switch the mode from "normal" to "overload" setting. This will cause the star-timer to start counting down. The star-timer output has three contacts, with one contact will be in open position and other two contacts will be in close position. The close contacts will be connected to the main supply circuit for the motor or the controlled equipment and will be in contact during the time of overload signal. This signal will last for 0-10 sec, depending on the setting, resulting in the motor to be in an overload condition temporarily.

When the timer will reach the set value, the relay will switch back to "normal" mode and the star timer contacts will open, and the motor or equipment will get disconnected from the supply. It sounds a warning bell to get the attention of operator and the operator should take the necessary measures to stop the overload situation. Once the corrective actions are taken, the operator should reset the UTP6A60MVL with the help of a handling tool. After resetting, the motor comes back to normal condition and is ready to work again.

The UTP6A60MVL provides various advantages and ensures safety in motor control in a variety of applications. The main advantage lies in the fact that it will protect the motor from the risk of getting overloaded and therefore it reduces the chances of premature motor burnouts and maintenance costs. The device is also equipped with adjustable range and time delay factors. Finally, the star timer provides reset and bypass functions for effective and reliable operations.
