Why Choose the ABB MCBH-11 Contact Blocks with Holder?
The ABB MCBH-11 is a modular contact block assembly with 3-position holder designed for ABB 22 mm pilot devices. Supplied as a ready-to-install combination, it includes one normally open (1 NO) and one normally closed (1 NC) contact block, providing two complementary contacts for industrial control and signalling circuits.
The MCBH-11 is intended for front mounting behind non-illuminated ABB Modular operators. Its included holder can accommodate up to three contact-block positions, while the supplied 1 NO + 1 NC configuration makes it suitable for applications requiring simultaneous make and break functions from a pushbutton, selector switch or compatible machine-control operator.
ABB's modular construction provides straightforward snap-in assembly with compatible operators and allows contact blocks to be installed or serviced efficiently. The MCBH-11 contact assembly has IP20 auxiliary-terminal protection and is identified by ABB order code 1SFA611605R1111.

Flexible Switching for ABB Modular Pilot Devices
The ABB MCBH-11 provides both normally open and normally closed switching functions in one convenient modular assembly. This configuration allows a compatible operator to make one circuit while simultaneously breaking another, making the assembly useful for control, interlocking and status-related functions within industrial machinery and control systems.
The included 3-position holder connects the contact blocks to compatible ABB Modular operators and simplifies panel assembly by eliminating the need to order the holder separately. Its modular snap-in construction also supports efficient installation, replacement and maintenance in industrial control panels.
Typical Applications
- Industrial pushbutton control circuits.
- Selector switch assemblies.
- Machine start and stop controls.
- Control and interlocking circuits.
- Industrial operator stations.
- Automation and OEM control panels.
