Why Choose the ABB MCBH-01 Block Holder with Contact Block?
The ABB MCBH-01, supplied under ABB order code 1SFA611605R1110, is a contact block with three-position holder for ABB modular plastic pilot devices. It is supplied with a single normally closed (1 NC) contact block, providing a convenient ready-configured switching component for compatible non-illuminated pushbuttons, selector switches and other operators.
The MCBH-01 uses front mounting and silver contact material, combining the holder and contact block in one compact assembly. Its normally closed contact provides the switching function required for control, signalling and machine-interface circuits where the contact must be closed in its normal state and open when operated.
Designed for ABB's 22 mm modular plastic pilot-device range, the MCBH-01 provides high electrical ratings and straightforward integration into industrial control panels. ABB's modular contact-block design also incorporates self-cleaning contacts to support dependable operation and long service life.

Contact blocks translate movement of a pushbutton, selector switch or other operator into an electrical switching action. The MCBH-01 provides a single normally closed contact, making it suitable for control circuits where continuity is required in the normal operator state and the circuit is opened when the associated operator is actuated.
By combining the contact block with a three-position holder, the MCBH-01 simplifies component selection and installation within ABB modular pilot-device assemblies. Its silver, self-cleaning contact system and industrial electrical ratings make it suitable for machinery, automation and general control-panel applications.
Typical Applications
- Industrial pushbutton assemblies.
- Selector-switch control circuits.
- Machine control and stop circuits.
- Automation and production equipment.
- Motor and process control panels.
- OEM machinery and operator stations.
- Industrial signalling and control functions.
