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 – adjustable 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
