Selection Notes

At 24 V AC/DC, this assembly runs directly off a standard low-voltage control transformer or 24 V DC panel supply, which is the usual choice for a machine's internal control circuit and keeps the illuminated contact body isolated from line voltage. Pick the 230...240 V ZB4BW0M13 sibling instead when the panel's pilot-device circuit is wired directly from the mains supply rather than a stepped-down control voltage.
