Siemens 3SB1400-0G Auxiliary Contact 2-Position Selector Switch

Siemens 3SB1400-0G is a two‑pole auxiliary contact block for Siemens 22‑ and 30‑mm 3SB selector switches and pushbutton assemblies, providing two normally open (NO) contacts to add a second signaling path in control circuits. The module mounts on the front plate of the 3SB operator and wires via screw terminals for straightforward field wiring, enabling reliable auxiliary signaling alongside the main switch action. With a 10 A control rating, it supports typical automation tasks such as status signaling, simple interlocks, or PLC feedback without requiring additional relays. As part of the 3SB family, this block is designed to extend the capabilities of 22/30 mm selector switches and pushbuttons in industrial control panels, offering a compact, front‑mounted solution for auxiliary circuits.
