Product Details
The Soltree ST2-VA2-2 combines overvoltage, undervoltage and overcurrent protection with an LED display and adjustable settings. The pictured white-housing version has a black display panel with rectangular control buttons and a red on/off button. It mounts on a DIN rail in an electrical distribution enclosure.
The following values come from the ST2-VA2-2 catalogue entry. They describe the documented AC configuration and its settings. Confirm the supply voltage, current rating and required settings for the version you intend to order. The current list describes catalogue configurations and does not confirm stock availability.

The overvoltage and undervoltage ranges above are protection-setting ranges, not the operating supply-voltage range. The 0.5 s technical-table entry is an overvoltage reference alongside the adjustable trip-delay menus; it is not a fixed response-time guarantee for every fault or supplied version. The voltage-accuracy reference has no stated test conditions and does not specify current accuracy. The catalogue label “maximum operating phase voltage” does not establish a continuous supply range, insulation withstand or surge rating.
Displayed values in product images do not define the rated supply voltage or current.
Logo customization is available on request. A 110 V version can also be customized. Its electrical ratings, protection thresholds, recovery settings and load suitability must be confirmed separately; the catalogue AC values above do not specify a 110 V version.
For a quotation, send the model ST2-VA2-2, required supply voltage and current rating, intended load, quantity, destination and logo requirements. We can then check the product configuration and supply details for your order.
