Modular Guarded Red Push Button (1NO)

Part number: MP Modular Push Button series - 2 22mm guarded - 10R 1NO, Red (e-stop)

ABB Modular (MP) Series Introduced circa 2005

Red guarded (shrouded) push button, ABB Modular series. 22mm cutout, IP65, with integrated 1NO contact. Guard ring prevents accidental activation.

Common Applications

Guarded (shrouded) red push button with a raised ring around the actuator to prevent accidental activation. Despite being red, this is a 1NO contact — used for critical functions where you want the red color to signal importance but need a normally-open circuit. Common applications include manual trip buttons on turbine control panels, purge cycle initiation on combustion systems, and conveyor reverse functions where accidental activation could cause equipment damage. The guard ring requires a deliberate finger insertion to press, eliminating bumps and brush-by activations in crowded panels.

Specifications

Actuator Shape The physical shape of the pressable surface.	Round
Actuator Type The button head style. Flush sits level with the bezel (prevents accidental presses). Extended protrudes for easy access.	Guarded (Shrouded)
Certifications Third-party safety certifications. UL = required for US NEC installations. CE = EU compliance. CSA = Canadian standards.	UL, CSA, CE
Color Button/actuator color. Green = start/go, Red = stop/emergency, Yellow = caution, Blue = reset (per IEC 60204-1).	Red
Contact Configuration Normally Open — circuit is off until you press. Standard for start/go/enable functions.	1NO
Cutout Diameter The hole size you drill in your panel to mount this button. 22mm is the most common industrial standard worldwide.	22mm
IP Rating IP65: Dust-tight and protected against low-pressure water jets. Suitable for indoor industrial and light washdown.	IP65
Material The bezel/body material. Metal bezels are more durable in harsh environments. Plastic is lighter and cheaper.	Plastic
Mounting Type How the button attaches to the panel. Panel mount is standard — installs through a cutout from the front.	Panel
Max Operating Temp Highest temperature the button is rated to operate in.	70°C
Min Operating Temp Lowest temperature the button is rated to operate in.	-25°C

1NO contact block for ABB modular push buttons

Installation Quick Reference

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.

Wiring Diagram

Troubleshooting

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.
