This switch box with an adjustable current protection of 6–10 A covers three-phase counter-current motors with a power input of 2.5 to 4.5 kW. Compared to the weaker version (4–6.3 A), it also handles the more powerful pumps used in mid- and higher-class counter-current units.
The electropneumatic switching principle brings a key safety advantage: all voltage remains enclosed within the box, while the user starts the device only with an air hose and a pressure button without any risk of electric shock.
The box is resistant to a humid environment and is designed for fixed mounting in the technical room or in a protected shelter near the pool. Compatible with A-JET NEW counter-current units and other brands powered from the 400 V network.
