Why Choose the ABB MPEK3-11R Emergency Stop?
The ABB MPEK3-11R is a robust 30 mm key-release emergency stop pushbutton operator designed for industrial machinery, control panels and automation systems requiring a secure and clearly identifiable emergency stopping control. Supplied under ABB order code 1SFA611522R1101, it forms part of ABB's modular plastic pilot device range and provides dependable operation in safety-related machine control applications.
The MPEK3-11R features a red 30 mm mushroom actuator with a maintained latching action and key-release mechanism. Once the emergency stop has been pressed, the actuator remains mechanically latched and requires the appropriate key to release it, helping prevent unauthorised or inadvertent resetting of the emergency stop function.
Designed for standard industrial control-panel installation, the MPEK3-11R uses a 22.5 mm mounting hole and features key code 455 / Ronis 455. The operator is non-illuminated, provides IP66 protection and is designed for use with separately selected ABB holders and contact blocks, providing a flexible solution for machinery and automation safety circuits.

Secure Emergency Stop Control for Industrial Machinery
Key-release emergency stop operators provide a clearly identifiable means of initiating an emergency stopping function while adding controlled access to the reset procedure. After activation, the mushroom actuator remains latched until the correct key is used, helping ensure that machinery cannot simply be reset at the emergency stop operator without authorised intervention.
The ABB MPEK3-11R combines a compact 30 mm red mushroom actuator with key-release operation and ABB's modular pilot device architecture. Compatible ABB holders and suitable contact blocks can be selected according to the safety circuit requirements, allowing the operator to be integrated into industrial machinery and automation systems.
Typical Applications
- Industrial machinery emergency stop controls.
- Production and manufacturing equipment.
- Conveyor and material handling systems.
- Packaging and processing machinery.
- Automation and machine control panels.
- Operator stations requiring controlled emergency-stop reset.
- OEM machinery and safety-related control assemblies.
