Coil Surge Absorber (New Series)｜Stable Contact Control Against Voltage Fluctuations

In environments with fluctuating voltages, electromagnetic contactors and auxiliary relays can suffer from arcing and wear. Hitachi’s new Coil Surge Absorber addresses this by providing built-in surge suppression and user-friendly installation. Whether used with 8–125C frame contactors or those in the 150–600C range, it ensures smooth, quiet switching and fewer failures.
Supported across industrial, commercial, and infrastructure applications, this absorber reflects Hitachi Asia (Thailand) Co., Ltd.’s commitment to maintaining superior electrical system performance across Southeast Asia.
