ABB MPEP4-10R Industrial Emergency Stop Pushbutton

The ABB MPEP4-10R is a red, 40 mm mushroom emergency stop pushbutton with pull-release actuation, part of ABB’s Modular Plastic (MP) range for panel-mounted control. It is a non-illuminated operator and ships without a contact block, so a compatible ABB contact block is required to complete the electrical interface. The device carries IP66 protection, providing dust-tight performance and protection against powerful water jets in demanding industrial environments. Official ABB designation for this model is 1SFA611524R1001, identifying the MPEP4-10R emergency stop within the modular plastic family. As a member of ABB’s MP emergency-stop lineup, it can be combined with other MP pilot devices and contact blocks to build a customized control panel. Typical applications include stop points on machinery, conveyors, presses, and automated lines where a clearly visible red E-stop is required; the pull-release mechanism is a defining feature of this variant.
