Description

The ABB AT/S4.20.1 is mainly suited for switching loads with high switch-on peaks such as shunt compensated fluorescent lamps. The actuator can activate the load circuit (for example, for functional or emergency lights) if the bus voltage fails. The output statuses are shown on the front, and manual control is available at any time, even when the bus voltage is not present. A separate power supply is not required for the gadget.
