The ABB MPEP4-10R is a robust modular emergency stop button designed to provide a reliable and immediate shutdown solution for industrial machinery and processes. Featuring a 40mm mushroom head and a pull-release mechanism, this button ensures quick and easy activation in emergency situations. The red, non-illuminated design provides clear visual indication of its function. It is commonly used in safety systems and control panels where rapid response is critical for personnel protection and equipment safeguarding. The button does not include a contact block and requires separate integration into a control circuit.
