Schneider Electric XB4 Emergency Stop Button, NC, Latching, 40mm

The Schneider Electric XB4 emergency stop button is a high-quality industrial control component engineered to ensure safety in critical operational environments. This latching button features a prominent 40mm head, designed for quick and intuitive activation during emergency situations. With its normally closed (NC) contact configuration, it provides a reliable circuit interruption when pressed, effectively halting machinery to prevent accidents. The device is constructed to withstand harsh conditions, offering robust protection against dust and water ingress, as well as significant impact resistance.

Advantages

This emergency stop button stands out due to its exceptional durability and industrial-grade build quality. The latching mechanism ensures that the button remains in the activated position until manually reset, providing a clear visual and physical indication of a safety stop. Its high ingress protection rating makes it suitable for environments exposed to moisture or debris, while the impact-resistant design ensures longevity even in high-traffic or heavy-duty industrial settings. The ergonomic 40mm head allows for easy operation, even when wearing protective gloves.

Suitable for

• Industrial machinery and production lines
• Control panels in manufacturing facilities
• Emergency shutdown systems for automated equipment
• Safety-critical electrical installations

This device may not be suitable for applications requiring a momentary contact action, as it is specifically designed to latch upon activation. Additionally, it is intended for industrial control systems and may not be appropriate for low-voltage consumer electronics or residential applications where standard light switches are used.

Key specifications

• Contact type: Normally Closed (NC)
• Operation: Latching
• Head diameter: 40 mm
• Ingress protection: IP66
• Impact resistance: IK06
• Dimensions: 47 mm height, 82 mm depth

To use the Schneider Electric XB4 emergency stop button, it must be mounted securely onto a compatible control panel or enclosure. Once installed, the button is ready for immediate use. In the event of an emergency, press the 40mm head firmly to trigger the normally closed contact and stop the connected equipment. To resume normal operation, the button must be manually reset according to the specific mechanical release method provided with the unit.

What to consider before purchase

• Ensure the NC contact configuration matches your safety circuit requirements.
• Verify that the panel cutout dimensions are compatible with the device.
• Confirm that the latching functionality meets your specific safety protocol.
• Check the environmental conditions to ensure IP66 and IK06 ratings are sufficient for your site.

Always perform a functional test of the emergency stop circuit after installation to ensure that the machinery halts correctly when the button is activated.
