Description
Features:Space-saving ECB with one channelReliably and safely trips in the event of an overload and short circuit on the secondary sideSwitch-on capacity > 50,000 μFEnables the use of an economical, standard power supplyMinimizes wiring via two voltage outputs and maximizes commoning options on both input and output sides (e.g., commoning of the output voltage on 857 and 2857 Series devices)Status signal – adjustable as single or group messageReset, switch on/off via remote input or local switchPrevents power supply overload due to total inrush current thanks to time-delayed switching on during interconnected operation
