 What is a DC Power Relay?


DC power relays are crucial items used in the heavy equipment and electrical industry. These relays perform high voltage and high capacity shutdowns of DC circuits during an emergency. Most of these relays are self-contained and built to withstand some of the most hostile environments on Earth. These relays will make sure that the DC unit is not energized and that they can shut down high-voltage systems when an error occurs to prevent accidents or equipment failures.

Modern DC power relays are built in a space-saving and easy to integrate format. The goal of these devices is to safely and reliably integrate into a high-voltage system and offer the safety solutions that are required for ongoing operations. The latest modern DC switchgear is often built in a solid-state and low power consumption format. They are tested rigorously for reliability and they can be designed to operate anywhere from belowground applications in mining sites to extremely high temperature exterior freight lines.

The switching structure in most types of DC switchgear is a gas ceiling system that can offer a long-term context ability and extremely fast result in the event of a failure. Easy switchgear comes with easy resets, screens, alarms and testing equipment to make sure that the relay works in a stable and predictable environment.

Modern DC power relays can be produced to run on solar power, small battery devices or integrated in a solid state and low power solution with battery backup. These devices are more crucial than ever before with many modern electric vehicles now requiring this type of safety gear during charging and throughout operation.
