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 μFMinimizes 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 – 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
