Engineered for high-voltage DC systems up to 1500 V DC, the EVH9AX-800G1BC ensures stable performance under frequent on-load switching -- ideal for electric vehicles, DC fast charging, and energy storage applications.
Unique dual-make contact design prevents contact welding during inrush current events -- critical for battery packs, chargers, and PCS systems where capacitive surges are common.
Epoxy-sealed body provides superior protection against dust, moisture, and vibration -- achieving [IP rating to verify] level protection without additional housing, suitable for harsh industrial environments.
Available with coil voltages of 12 V DC, 24 V DC, or 48 V DC, making integration easy across various low-voltage control systems in EVs, charging piles, and industrial equipment.
SPST-NO-DM power contact with optional auxiliary contact (NO / NC / None). Rated current up to 800 A covers demanding high-power EV and energy storage applications. Modular mounting for easy installation and replacement.
CE, ISO9001:2015, TUV, CCC certified. Quality management system conforms to GB/T19001-2016 / ISO9001:2015.

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.
