This Main Switch – Energy Storage System label is designed for clear identification of the main switch controlling a battery energy storage system. Featuring red text on a white background, it is visually distinct from standard isolator and circuit labels, supporting safe operation and emergency identification.
 
Sized at 19 × 19 mm, this label is suitable for installation within switchboards where compact, high-visibility identification is required.
 
Red text is recommended for main switch identification in accordance with AS/NZS 3000:2018 Clause 2.3.3.5, which requires main switches to be clearly distinguishable from other devices.
