Description
Features:Space-saving ECB with two channelsNominal current: 2 … 10 A (adjustable for each channel via sealable selector switch)Switch-on capacity > 23000 μF per channelOne illuminated, three-colored button per channel simplifies switching (on/off), resetting, and on-site diagnosticsTime-delayed switching of channelsTripped message (common group signal) via isolated contact (13 / 14)Remote input resets all tripped channelsPotential-free signal contact 13 / 14 reports “channel switched off” and “tripped channel” – does not support communication via pulse sequence
