Visible Load Break
Transformer

The ETAC Visible Load Break Transformer (VLBT) incorporates an integrated load break switch equipped with a mechanical viewing window, enabling direct visual verification of the switch position for enhanced operational safety. The viewing window provides clear indication of open and closed states of the load break switch, which is actuated by a gang-operated handle. Load Break Switch configurations are available in 2-position and 4-position variants, supporting reliable circuit interruption and connection functions in compliance with typical high-voltage distribution and switching requirements.
