Selection Notes

The 'I' legend reads as the IEC 60417 symbol for 'on' or energise, so this marked green head suits panels where the function has to be legible without relying on colour alone, such as mixed-language sites. It is the marked counterpart to the plain green XB5AA31 head: pick this one where the control scheme calls for a printed symbol, the unmarked head where panel labelling is done separately. The 1NO contact switches directly into a PLC input or control-relay coil within its 3 A/240 V AC-15 rating.
