Item description
Features:
Space-saving ECB with one channel
Reliably and safely trips in the event of an overload and short circuit on the secondary side
Switch-on capacity > 50,000 μF
Enables the use of an economical, standard power supply
Minimizes 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 message
Reset, switch on/off via remote input or local switch
Prevents power supply overload due to total inrush current thanks to time-delayed switching on during interconnected operation
