Siemens 3SB3400-0E Contact Block 2 Position

Product Description

The SIEMENS 3SB3400-0E is a contact block designed for use with modular pushbutton and selector switch assemblies in industrial control applications. It provides the electrical switching element that completes or interrupts a control circuit when the operator device is actuated. The block snaps onto a compatible front element or switch body and is a replaceable component, making it straightforward to service existing panel assemblies without replacing the full switch unit. Licensed electricians and industrial controls technicians are the primary installers of this device in machine control and panel-wiring environments.

The 3SB3400-0E is suited for use in control panels, motor control centers, and machine tool enclosures where compact, modular pushbutton stations are required. It is intended for low-voltage control circuit applications typical of industrial automation settings. The 2-position contact configuration supports standard normally open or normally closed circuit functions depending on the specific variant. This block is commonly installed during new panel builds or as a direct service replacement in existing Siemens 3SB series switch assemblies.
