ABB, Pull Release, Emergency Stop Push Button Head 40 mm Diameter

This emergency stop push button head provides a clearly visible, manually operated means to interrupt machinery in industrial control panels. Designed for panel mounting in automation and electrical systems, it delivers immediate tactile actuation with an illuminated indicator to show status. The unit is suitable where a prominent, quick-access stop control is required and where hazardous-area certification is not necessary.

• 22.5mm cutout for Compact panel integration
• Illuminated indicator for clear operational status visibility
• Pull release action for deliberate reset after activation
• 40mm red mushroom cap for Rapid manual engagement
• Plastic construction offering corrosion‑resistant handling
• Dual ingress ratings providing internal and external protection

• Suitable for emergency stop stations in assembly lines
• Ideal for control panels in factory automation racks
• Used with machinery requiring visible stop annunciation
• Can be used for retrofit upgrades of existing control enclosures
• Used for safety interfaces in electrical distribution cabinets

It uses a pull‑release mechanism so the operator must perform a deliberate reset action, reducing accidental re‑engagement and ensuring control is restored intentionally.

The built‑in light offers immediate Visual confirmation of the button’s state, assisting technicians in locating tripped circuits and speeding fault‑finding during shutdowns.

It carries IP20 protection for general enclosed‑panel environments and an IP66 rating for resistance to strong jets of water and dust when mounted appropriately, allowing use across varied conditions.

It is not certified for hazardous areas, so it should not be specified where explosion‑risk certification is required.
