UTPCH43BLY is a three-phase, high-performance Digital Protection Relay (UTPCH) designed and manufactured according to the latest European Standard 61850-3. It provides robust protection and control features for medium and large industrial and power applications. The device is equipped with several communication ports including Ethernet and USB. It is used to protect three-phase AC and DC circuits, power transformers, and DC motors from various faults such as overloads, phase faults, and imbalances.

The UTPCH43BLY protection relay provides comprehensive protection for medium and large industrial and power applications by taking into account both fault current and fault voltage. The device uses various types of current measurements including RMS, peak, and crest, along with voltage measurements such as voltage-rise or drop, to detect and trip on faults quickly and accurately. The device is designed with integral monitoring features to detect behavior of the busbar and also includes a digital output circuit breaker with a trip bank capability for better control over the overall system.

In addition to providing overcurrent and over voltage protection, the UTPCH43BLY is capable of providing multiple protection functions such as undervoltage protection, imbalance protection, motor protection, and ground fault protection. The device also provides overfrequency, underfrequency, and forward power protection. The device uses a specially designed algorithm for trip banking which allows it to trip on multiple faults quickly and accurately, providing protection to the system in a reliable manner. The device also features an event recorder that stores the most recent trips and provides detailed information on the events that occurred before, during, and after the trip.

The UTPCH43BLY operates on 24V AC or DC power. The device is also equipped with numerous configurable options such as pick-up and trip settings. The device has a built-in intelligent configuration system which makes the set up process easier and ensures that the device is configured correctly according to the user’s requirements. The device can also be operated remotely via a web-based interface.

The UTPCH43BLY is designed to offer reliable and comprehensive protection to circuits and equipments. It is also field-tested and certified to meet the safety standards of the respective industrial and power applications. The UTPCH43BLY provides a great level of flexibility and scalability as users can configure the device as per their requirements and change the configuration whenever their needs change.
