Schneider Electric Emergency Stop Push Button, 40mm Actuator Diameter, Screw Clamp Terminals - Harmony XB4 Series - XB4BS8442
Put the brakes on faulty machinery with this emergency stop push button from Schneider Electric. It cuts power to your circuit when you push it, making it safe to inspect your equipment. The unit's twist-release actuator stays latched until you've addressed the fault, so there's no need to worry about accidental reactivation. Compatibility with a commonly used cutout diameter of 22mm makes the unit a sure fit for standard panels. It has an IP69K rating, meaning it's sealed against dust and handles the high-temperature, high-pressure water jets you'd expect in hygiene-critical settings.
Features & Benefits
• Flat button head with a diameter of 40mm for ease of operation, even in gloves
• Silver alloy contacts are highly conductive and resistant to corrosion, so you get a reliable connection
• Bright red actuator stands out on a crowded panel
• Long electrical lifespan of 1 million operations for long-lasting performance
Applications
• Workshops
• Packaging lines
• Manufacturing industry
Do I need to assemble this push button before installation?
No, this product comes as a pre-assembled actuator and contact block, so you can get straight to installation.
