ABB 3BHB044356R0001 Capacitive Switch Module

Product Overview

The ABB 3BHB044356R0001 is an industrial‑grade capacitive switch module manufactured by ABB. Unlike high‑power semiconductor modules such as IGBT modules, this component functions as a sensory/control switch that detects capacitance changes and carries a control signal. It is used in control panels, automation systems, and machinery interfaces where precise contact switching is required.

This part is commonly found within larger assemblies and electrical panels as a reliable ancillary peripheral, rather than as a main power conversion device.
