Siemens 3SB3 803-3AZ Emergency Stop Push Button Enclosure

Siemens 3SB3 803-3AZ Three Hole Enclosure With Twist On And Push Emergency Stop is an empty three-hole enclosure designed to house a Siemens SIRIUS 3SB3 emergency stop mushroom pushbutton and related accessories. It accepts 3SB3 pushbuttons, contact blocks, lamp holders, and other snap-on base mounting components, and supports front-plate mounting as well as installation inside a panel or enclosure as part of a distributed emergency-stop configuration. The enclosure is intended for twist-on and push-actuated emergency stop devices, providing a compact, modular housing that keeps the operator's stop control accessible and protected in industrial environments. As part of the SIRIUS 3SB3 family, this empty enclosure enables users to assemble a complete E-stop interface from modular parts, facilitating precise placement of the actuator and its hardware. Its three-hole design aligns with the 3SB3 layout and works with compatible contact blocks and lamp holders that snap into place for reliable stop signaling. This enclosure is commonly used in safety-critical control circuits on machinery and automation equipment, where quick, unambiguous actuation and robust enclosure protection are required.
