Selection Notes
The black, unmarked flush head follows IEC 60073 colour coding for a general-purpose actuator with no mandated function, unlike the green/red colours reserved for start/stop. Its plastic bezel resists chemical agents and provides double electrical insulation, a reason to prefer it over the metal XB4 range in washdown or corrosive areas. The single 1NO contact switches directly into a PLC input or control-relay coil within its 3 A/240 V AC-15 rating without an interposing relay.
