Why Choose the ABB MCBH-02 Block Holder with Contact Blocks?
The ABB MCBH-02 is a modular contact block assembly with holder and two normally closed (2 NC) contacts, designed for ABB's 22 mm modular pilot device range. Supplied under ABB order code 1SFA611605R1120, it provides the rear-mounted switching elements required for compatible pushbuttons, emergency stop operators and other modular control devices.
The MCBH-02 combines a three-position contact block holder with two NC contact blocks in a ready-to-install assembly. Its normally closed configuration makes it particularly suitable for stop and emergency-stop control circuits where contacts are required to open when the associated operator is actuated.
Designed for front-fastened 22 mm pilot devices, the MCBH-02 uses screw connections for straightforward control-panel wiring. The compact modular assembly weighs approximately 0.032 kg and is compatible with a broad range of ABB modular operators, allowing contact functions to be configured efficiently within industrial machinery and automation panels.

Contact blocks convert the mechanical movement of a panel-mounted operator into electrical switching within a control circuit. With its 2 NC configuration, the ABB MCBH-02 provides two normally closed contact paths that change state when the associated compatible operator is actuated, making the assembly useful for stop-related control functions and other circuits requiring normally closed contacts.
The integrated holder simplifies installation by combining the contact blocks and mounting interface into one modular assembly. The MCBH-02 can be paired with compatible ABB modular pushbuttons, emergency stop operators and selector switches, providing a convenient method of configuring the required switching arrangement behind the front-panel operator.
