ABB EHD-130 Relay

The ABB EHD-130 Relay (EHD130) is a legacy industrial control device originally designed by ASEA BROWN BOVERI and later incorporated into ABB’s catalog. Listed in ABB’s range as an A Contactor, the EHD-130 functions as a power switching device used to energize and de-energize higher‑current circuits within machine control and automation panels in response to control signals. The EHD-130 designation identifies a specific model within the historical EHD family, with the EHD130 variant appearing in legacy installations and cross‑references in ABB’s documentation. These contactors are employed as the main switching element to start and stop motors or to redirect power to heavy loads in industrial control schemes, delivering robust mechanical contacts and reliable operation for repetitive use in challenging environments. In practice, the EHD-130 serves where durable, field‑proven switching is required, aligning with ABB’s long‑standing approach to dependable electromechanical control components.
