The lid of the MENNEKES connection box (available as a separate accessory) for AMTRON® Professional Twincharge is designed to allow the box to be pre-installed even without the product, facilitating larger installations. In these cases, the lid securely seals the connection box until the wallbox is added later. The lid is also useful in repair situations, as the entire installation can continue to operate smoothly until the dual wallbox is ready for use again.
