Electronic overload relays
Operating principle of electronic overload relays
As overload relays are an indispensable component to protect your motor, and your machine, advancements have been made to improve the technology through the years. While thermal overloads were previously used exclusively, they were imperfect in that they could be affected by changes in ambient temperature. Electronic overload relays do not use a thermal method of detection so are therefore unaffected by this issue, and are as a result more accurate.
Applications for electronic overload relays:
- Motor overload
- Phase failure
