The electronic expansion box is an accessory designed to extend the functionality of Wilo-Isar BOOST5 series pumps. It enables external pump shut-off via a switch (e.g. a float switch) and provides external fault signalling, thereby increasing integration options within more complex control systems.

The box has compact dimensions and is supplied as a complete set including a printed circuit board, cable terminals, cable gland, O-rings and screws – everything required for immediate installation is included in the package.
