ABB MPMT4-11R Emergency Stop Push Button

ABB MPMT4-11R is a 60 mm modular emergency-stop push button with a red, illuminated actuator designed for CombiLine modular panels. It carries the part number 1SFA611513R1101 and is described as a NOT AUS (emergency stop) pushbutton with a twist-release (Drehentriegelung) mechanism, enabling a secure latch and manual reset after actuation. As part of ABB's CombiLine family, it is intended for panel-mounted safety circuits in industrial automation and can be paired with ABB contact blocks and bezel options to tailor the safety function. The illuminated red indicator enhances visibility in low-light environments, and the 60 mm diameter fits standard control enclosures. Typical applications include emergency stop circuits on machinery such as presses, conveyors, CNC machines, and packaging lines where immediate de-energization of equipment is required.
