Indication of the position of the device’s contacts. S2C-H01 is the opening device and S2C-H10 the closing device. Compared to the S2C-S/H6R, the S2C-H10 entails less cost and many practical benefits. It can be fitted at the bottom of the MCBs and RCDs and is thus much more convenient for retrofitting than the side-mounted device because not all MCBs have to be removed from the rail first. And even when the MCBs affected are connected to a busbar, they do not have to be removed. 50% space can be saved. Suitable for MCBs S200 series, electronic RCBOs DSE200 series.
