ABB Emergency Stop Push Button Head, 30mm Cut-out Diameter, Red Push Button Diameter - 1SFA611521R1001 MPEP3-10R

This emergency stop push-button head provides a manual means to interrupt machinery operation in industrial control panels and equipment. Designed as a mushroom-style actuator in red plastic, it is intended for use where a prominent, easily operated shutdown control is required. The unit is not illuminated and employs a pull-release actuation for reset, making it suitable for systems where clear manual intervention and visible status are needed.

Features and Benefits:

• 30mm diameter actuator delivers easy manual engagement
• Pull-release mechanism ensures positive manual reset
• Plastic construction reduces weight and corrosion risk
• Red mushroom style offers Rapid Visual identification
• IP20/IP66 ratings permit use in dry enclosures and in harsh conditions

Applications

• Suitable for panel-mounted machine emergency shutdowns
• Ideal for safeguarding automated production lines
• Used with control stations in electrical distribution cabinets
• Can be used for safety stops on assembly-line equipment

How is the head reset after activation?

It uses a pull-release method requiring a manual pull to restore the actuator to its operating position.

Is the head usable where environmental ingress is a concern?

The design carries both IP20 and IP66 ratings allowing installation inside enclosures and in locations exposed to dust and powerful water jets when properly mounted.

Does the actuator include illumination for status indication?

No, the head is non-illuminated and provides status visually solely via its red mushroom shape.

What material considerations affect installation and longevity?

The actuator is moulded from plastic, which lowers susceptibility to corrosion and reduces overall component mass during panel assembly.
