1SFA611522R1301 ABB MPEK3-13R 30 mm Key-Release Emergency Stop Pushbutton

Why Choose the ABB MPEK3-13R Emergency Stop?

The ABB MPEK3-13R is a modular 30 mm key-release emergency stop pushbutton operator designed for safety-related control on industrial machinery, production equipment and automation systems. Part of the ABB modular plastic pilot device range, it features a highly visible red mushroom-head actuator and a keyed release mechanism for controlled resetting after emergency-stop actuation.

The MPEK3-13R provides a maintained emergency-stop function with key code 73 / Ronis 3433-E. Once the mushroom actuator is pressed, the operator remains mechanically latched until it is deliberately released by turning the appropriate key. This makes it particularly suitable for installations where controlled resetting is required and unintended manual release should be prevented.

Designed for the standard 22 mm industrial pilot-device mounting system, the MPEK3-13R is a non-illuminated operator with a 30 mm red mushroom actuator. Its IP66 protection rating supports use in demanding industrial environments, while the modular ABB design allows appropriate holders and contact blocks to be selected separately for the required emergency-stop circuit.

Controlled Emergency-Stop Reset for Industrial Machinery

Emergency-stop pushbuttons provide operators with an immediately recognisable means of initiating a machine stop when an emergency condition occurs. The ABB MPEK3-13R uses a 30 mm red mushroom actuator that mechanically latches after operation, ensuring that the operator remains in its actuated state until a deliberate reset action is performed.

The key-release mechanism provides additional control over resetting compared with freely accessible twist- or pull-release operators. The MPEK3-13R requires the appropriate Ronis 3433-E key for release, making it well suited to machinery where reset access needs to be controlled. Compatible ABB holders and contact blocks can be selected according to the electrical and safety requirements of the application.

Typical Applications

• Industrial machinery emergency-stop stations.
• Production and manufacturing equipment.
• Conveyor and material handling systems.
• Packaging and processing machinery.
• Machine-tool control panels.
• Restricted-access equipment requiring controlled keyed reset.
• OEM machinery and industrial automation systems.
