A motor protection relay safeguards electric motors by detecting thermal stress, phase imbalance, stall, and abnormal ...

ABB has installed more than 700,000 SPACOM relays used for power system protection and reliable power system operation world-wide. With the older generation of relays now aging, ABB is developing new ...

Most industrial facilities include electric motors that require overload relays for protection, control and monitoring purposes. The latest overload relays are often called motor management relays ...

The objective of protective relays and protective schemes is to protect electrical equipment such as transformers, lines, cables, bus bars, etc. during abnormal system conditions. Hence, protective ...

Differential protection is best understood as a fault control philosophy rather than a component category. The relay itself is secondary to the scheme it enforces. Once a zone is defined, the system ...

RF coaxial SPDT relays address signal-routing applications that demand a combination of high frequency, high power, and excellent RF performance. What role does an SPDT relay play in test applications ...

Hybrid relays are changing the way we think about switching inside electronic circuits. By combining the fast response of solid-state components with the reliability of mechanical contacts, these ...

Long before tubes and semiconductors became the main active components in digital circuitry, relays were used for highly sophisticated control of electronic systems. Today’s retro-engineering and ...
