ZB4-BA4
ActivHarmony XB4 Red Flush Push Button Head
Red flush push button head for Schneider Harmony XB4 series. 22mm cutout, IP66 rated. Requires separate contact block (ZB4-BZ102 for 1NC).
Aplicații frecvente
Standard stop button across industrial control panels. Found on commercial kitchen equipment alongside the green ZB4-BA3 (start), CNC machine tool auxiliary stops, and conveyor emergency halt stations. Red color follows IEC 60204-1 meaning stop or off. The 1NC contact configuration breaks the circuit when pressed — wire it in series with the motor contactor coil so pressing the button kills power to the motor.

Referință rapidă de instalare
Panel cutout: 22mm. Insert from the front of the panel, secure with mounting nut from behind (tighten to 2-3 Nm).
Contact block: Snap or screw the contact block onto the rear of the button body. Ensure the contact block orientation matches the wiring diagram — NO terminals are usually marked.
Wiring: Use 0.5-2.5mm² stranded wire with ferrules. Tighten screw terminals to 0.8 Nm. Test the button function before energizing the circuit.

Schemă de cablare
Depanare
Button doesn't respond when pressed
Check the contact block first — it's the most common failure point. Test continuity across the NO or NC terminals with a multimeter. If no click is felt, the return spring in the head may be broken.
Works intermittently
Contact block contacts are pitted or burned. Replace the contact block — don't try to file the contacts. Check if the rated cycle count has been exceeded.
Button feels mushy or doesn't click
The spring return mechanism in the button head is worn. Replace the head. The contact block can usually be reused if it tests OK.
