ABB Emergency Stop Push Button Head, 30mm Button Diameter, 22.5mm Cut-out Diameter - 1SFA611522R1301

This emergency stop push button head provides a manual shutdown Interface for industrial control systems, designed for use where Rapid human intervention is required. It offers a non-illuminated, plastic mushroom actuator in a high-visibility red finish, configured for key release operation and intended for panel mounting in control enclosures.

Features and Benefits:

• Key release actuation prevents accidental reset while allowing deliberate restart
• IP66 protection against jetting water and dust ingress
• IP20 protection for internal, unassembled components
• 30mm diameter mushroom gives rapid, unambiguous actuation
• Plastic construction reduces weight and resists corrosion
• 22.5mm cut-out compatibility simplifies panel installation

Applications

• Suitable for emergency stop interfaces on production machinery
• Ideal for control panels in automated assembly lines
• Used with safety circuits requiring positive manual interruption
• Can be used for machinery where Visual emergency indication is unnecessary

Is this head suitable for use in hazardous atmospheres?

It is not certified for hazardous-area use and should not be installed where intrinsic-safety or explosion-protection certification is required.

How does key release operation affect reset procedures?

The actuator remains latched until a key is used to release it, allowing controlled reset only by authorised personnel.

What mounting provision does it require?

The unit is designed to fit a 22.5mm panel aperture for straightforward replacement or retrofit.

Does the head include illumination or lamps?

No illumination is provided

the design is a plain, non-illuminated manual actuator.

Can this be used as a replacement component in existing assemblies?

It is suitable as a replacement head for compatible emergency stop assemblies that accept 22.5mm cut-out mushroom actuators.
