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 < 6,000 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
