ZB4-BP2
AttivoSchneider ZB4BP2 Black Projecting Pushbutton Head (Harmony XB4)
Schneider XB4 red guarded (shrouded) push button.
Applicazioni Comuni
Guarded button with a raised ring around the actuator that prevents accidental presses. Used for stop buttons near moving machinery where operators might lean against the panel. The guard forces deliberate pressing — you have to reach over the ring to press the button. Also used for critical functions where accidental activation would be costly.

Actuator Function
Momentary = springs back when released. Maintained/latching = stays pressed until pressed again.
|
Momentary

|
Actuator Type
The button head style. Flush sits level with the bezel (prevents accidental presses). Extended protrudes for easy access.
|
Projecting (raised, ~Ø29.5mm cap)

Cutout Diameter
The hole size you drill in your panel to mount this button. 22mm is the most common industrial standard worldwide.

Guida Rapida all'Installazione
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.

Risoluzione dei Problemi
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.
