The MT12/V-GRND is an industrial device used globally to protect complex power delivery systems from overload, providing reliable and efficient electrical conditioning and protection. This device offers both current overload and ground fault protection, helping to reduce energy consumption and minimize the risk of electrical shock or fire. In this article, we will explore its application field and working principle.

The MT12/V-GRND is commonly used in industrial settings where large power loads must be protected from overload and ground faults. In particular, the device is ideal for heavy machinery, such as mining equipment, pumps, and compressors, as well as high-load electric motors, transformers, and other electrical systems. The device can be installed as a self-contained system or within a network of other equipment, such as protection relays, transducers, and power conditioners. The device can also be used to provide surge protection for lighting circuits and installed in both indoor and outdoor environments.

In addition to providing reliable protection from overload and ground faults, the MT12/V-GRND also offers current monitoring capabilities. It is equipped with a current indicator, which helps to identify and monitor potential overloads and ground faults. This current indicator is adjustable and can be set to automatically shut down the system when an overload or ground fault is detected, providing an added layer of protection to prevent catastrophic damage from occurring.

The MT12/V-GRND operates using a thermal-magnetic trip action, which allows it to trip out and reset itself quickly and reliably when overloaded. The device utilizes a three-phase motor winding temperature monitoring system, which ensures that the winding temperature stays within acceptable limits. In addition, the device also features a built-in time delay feature that helps to protect against nuisance tripping due to momentary overloads. After tripping, the device must be manually reset.

The MT12/V-GRND is easy to install and it is designed to be connected with standard wiring and fasteners. The device may be wall mounted or installed in either a shielded or unshielded panel box, depending on the installation requirements. The device is also tested and certified to UL and CSA standards and compliant with National Electric Code requirements.

The MT12/V-GRND is a versatile and reliable device that provides effective overload and ground fault protection for industrial power delivery systems. The device can be quickly and easily installed and offers a range of features, including adjustable current protection and visual indication of faults. With its thermal-magnetic trip action technology and other safety features, the MT12/V-GRND helps to ensure maximum energy efficiency and minimize the risk of dangerous electrical accidents.
