Why Choose the ABB MPEK3-12R Emergency Stop?
The ABB MPEK3-12R 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 reset mechanism for controlled release following emergency-stop actuation.
The MPEK3-12R uses key code 421 for its release function. Once the emergency-stop mushroom has been pressed, the operator remains mechanically latched until it is deliberately released using the appropriate key. This arrangement is particularly useful where controlled resetting of an emergency-stop device is required and unrestricted manual reset is undesirable.
Designed for ABB's 22 mm modular pilot-device system, the MPEK3-12R is a non-illuminated operator with a 30 mm red plastic mushroom head. It provides IP66 front protection and can be combined with a compatible ABB holder and contact blocks to create a complete emergency-stop control assembly.
Key Advantages
- Highly visible 30 mm red mushroom emergency-stop actuator.
- Key-release operation with key code 421 for controlled resetting.
- Maintained mechanical latching keeps the operator actuated until deliberately reset.
- Designed for the standard 22 mm ABB modular pilot-device system.
- IP66 front protection for demanding industrial environments.
- Conforms to EN/IEC 60947-5-5 requirements for emergency-stop devices.
- Modular construction allows suitable ABB holders and contact blocks to be selected for the required safety circuit.

- Unit weight of approximately 0.065 kg.
- Designed for modular assembly with compatible ABB holders and contact blocks.
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 MPEK3-12R uses a 30 mm red mushroom actuator that mechanically latches after being pressed, helping ensure that the emergency-stop operator remains actuated until an intentional reset is performed.
Unlike twist- or pull-release emergency-stop operators, the MPEK3-12R requires the appropriate key code 421 to release the mechanism. This keyed arrangement provides additional control over resetting and can help prevent unauthorised or unintended release of the emergency-stop operator. Compatible ABB holders and contact blocks are selected according to the electrical and safety requirements of the machine.
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 industrial equipment requiring keyed reset.
- OEM machinery and automation systems.
