Description
This Harmony XB4, Emergency stop 40mm mushroom red button head operates with a latched turn-to-release mechanism. This emergency stop / shutdown button head is easily combined with contact blocks and installed into standard 22mm diameter cut-outs and connected with simple screw-clamp connections. It is clearly distinguishable visually at a distance thanks to a clear color and a prominent 40mm mushroom shape. It is impact resistant, dust resistant, water resistant and vibration resistant thanks to its IP66 / IP67 / IP69 / IP69K. It has a metal bezel, this makes it Ideal for applications requiring high impact and vibration resistance. It is designed to fit in a standard 22mm cutout, ensuring compatibility when installing in pre-existing machinery. Its wide range of operating temperatures from -40°C to 70°C allows versatility in usage of product.
Features
- The ZB4BS844 is a high-performance, 40mm "Mushroom Head" Emergency Stop (E-Stop) operator from the Schneider Electric Harmony XB4 metal range. It features a Trigger Action design with a Turn-to-Release mechanism, ensuring that the machine stays stopped until the operator manually resets the button by twisting it.
- This unit is engineered with "Trigger Action" (also known as "tease-proof") functionality. This means the internal electrical contacts will not change state until the button is fully latched in the depressed position. This prevents a machine from stopping and then immediately restarting if the button is only partially pushed, meeting strict ISO 13850 safety standards.
- Built with a robust chromium-plated metal bezel, the ZB4BS844 is designed for the most demanding environments. It is rated IP66, IP67, IP69, and IP69K, making it completely dust-tight and resistant to high-pressure, high-temperature washdowns—ideal for food processing, automotive, and heavy industrial applications.
- The mushroom head is a vibrant, non-fading red, providing immediate visibility for operators. While this part number is the operator head only, it is designed to be paired with a yellow "Emergency Stop" legend plate and the ZB4BZ009 mounting collar to ensure it is clearly identifiable and compliant with global safety color-coding regulations.
- As part of the modular XB4 system, this head requires a mounting collar (ZB4BZ009) and contact blocks (typically ZBE102 for Normally Closed/NC logic) to become a functional switch. Its "snap-fit" mounting system allows for quick assembly and easy replacement of the head without disturbing the underlying wiring.
