ABB Key Release Emergency Stop Push Button Head 30 mm Diameter 1SFA611522R1201

ABB 1SFA611522R1201 Emergency Stop Push Button Head is designed for rapid manual interruption of machinery power in industrial and electrical control panels. Its 30 mm diameter red mushroom actuator provides a large surface area for easy and deliberate activation, improving safety response times in emergency situations.

The key release actuation mechanism prevents unauthorized or accidental resets, ensuring that machinery can only be restarted intentionally with a proper key-operated release. This safety feature enhances operator protection and regulatory compliance in industrial environments.

Constructed from durable plastic, the mushroom-style button is lightweight yet sturdy, offering a reliable grip without electrical conductivity risks. Its vivid red colour enhances visual identification within safety circuits, even in low-light or visually cluttered control panels.

This push button head is compatible with standard 22.5 mm cutout dimensions common in industrial control setups, allowing straightforward retrofit or replacement applications. The external IP66 rating protects against dust ingress and powerful water jets, making it suitable for harsh environments, while the internal IP20 rating ensures safety inside the enclosure.

The product finds applications in factory automation panels, electrical distribution boards, and mechanical fabrication environments. It can be used effectively for emergency shutdown systems on control stations and as safety interface components in electronics assembly lines, contributing to workplace safety and machine protection.
