Product Description

The SIEMENS 52RB3D3 is a mushroom-head pushbutton accessory designed for use in industrial and commercial control panel applications. This compact operator component mounts to compatible pushbutton assemblies and provides a large, easily actuated surface for emergency stop, lockout, or process control functions. The part weighs 0.044 pounds and measures approximately 0.559 x 0.449 x 0.031 inches, making it a low-profile addition to existing button assemblies. Licensed electricians and industrial control technicians are the typical installers of this type of component.

Mushroom-head pushbutton accessories like the 52RB3D3 are commonly used in motor control centers, control panels, and machine operator stations.
