This device is specifically designed to operate on a 3-phase power system with a voltage rating of 490 volts, making it suitable for industrial and commercial electrical installations.

The TVM-400-20-0002 is a voltage relay, which means it is designed to detect and respond to changes in the voltage level of the electrical supply. It is capable of operating at both 50 and 60 Hz frequencies, making it a flexible solution for applications in different regions with varying power system frequencies.

This relay features a robust and compact design, with a rugged enclosure that can withstand harsh operating conditions. It is designed to mount easily on a DIN rail, making it a space-saving solution for control panels and electrical distribution boards.

The TVM-400-20-0002 is equipped with a tripping mechanism that responds to voltage under- or over-voltage conditions. The relay has adjustable settings that allow users to customize the voltage sensitivity and tripping thresholds to meet their specific application requirements.

The relay also features a clear and easy-to-read LED indicator that provides visual feedback on the status of the device. It has a built-in test function that enables users to perform routine tests and maintenance checks to ensure the proper functioning of the relay.

The R-K TVM-400-20-0002 3-phase voltage relay is a high-quality protective device that offers reliable and accurate voltage detection and tripping functions. Its rugged design, flexibility, and ease of use make it an excellent choice for industrial and commercial electrical installations where voltage protection is essential.

The R-K TVM-400-20-0002 3-phase voltage relay is a protective device designed to disconnect a power circuit when the voltage falls below or rises above a specified level. Here are some pros and cons of buying this specific model:

1. High Voltage Rating: This relay is rated for 490V AC, making it suitable for industrial applications requiring high voltage protection.

2. Wide Operating Frequency: It can operate at both 50 and 60 Hz, making it versatile and adaptable to various power grid systems.

3. Robust Construction: The relay is designed to withstand harsh industrial environments, ensuring reliable operation.

4. Easy Installation: The relay is simple to install, making it an ideal choice for small to medium-sized projects.

1. Limited Current Capacity: The relay has a limited current capacity of 20A, which may not be sufficient for heavy-duty applications.

2. No Remote Mounting Option: The relay must be mounted directly on the DIN rail, making it less flexible for certain installation scenarios.

3. No Built-in Overload Protection: This relay does not have built-in overload protection, which may require additional protective measures.

The R-K TVM-400-20-0002 3-phase voltage relay is a reliable and versatile protective device suitable for industrial applications requiring high voltage protection. Its wide operating frequency range and robust construction make it a popular choice among engineers and technicians. However, its limited current capacity and lack of remote mounting and overload protection options may limit its applicability for some projects. When considering this relay for your application, carefully evaluate your power requirements, installation constraints, and available budget to determine if it is the best choice for your needs.

If you require a voltage relay with a higher current capacity, consider the R-K TVM-630 series or similar models. If remote mounting is necessary, consider models with that feature. Lastly, if overload protection is essential, consider purchasing a separate overload relay to ensure comprehensive protection for your power circuits.
