A: The EVH9AX-800G1BC supports a maximum switching voltage of 1500 V DC, making it suitable for high-voltage electric vehicle and energy storage applications.
A: The contactor is available with 12 V DC, 24 V DC, or 48 V DC coil voltages. Select the option that matches your control system when ordering.
A: Yes. The EVH9AX-800G1BC is designed for energy storage systems (ESS), including generation-side, grid-side, industrial & commercial, and residential applications. Its high current rating (800 A) and 1500 V DC voltage make it ideal for large-scale battery banks and PCS systems.
A: The power contact uses an SPST-NO-DM (Single Pole Single Throw, Normally Open, Dual Make) configuration. An optional auxiliary contact is available in SPST-NO, SPST-NC, or none.
A: The EVH9AX-800G1BC is rated for 800 A -- significantly higher than standard models (e.g., 50 A, 150 A, 300 A). It is specifically engineered for high-power applications such as ultra-fast DC charging piles and large-scale energy storage, where lower-current contactors cannot safely operate.
