Why Choose the ABB MCBH-03 Block Holder with Contact Blocks?
The ABB MCBH-03, supplied under ABB order code 1SFA611605R1130, is a three-position block holder supplied with three normally closed contact blocks for ABB modular plastic pilot devices. It provides a convenient pre-assembled switching solution for compatible pushbuttons, selector switches and other non-illuminated 22 mm operators.
The MCBH-03 provides a 3 NC contact configuration, giving three independent normally closed switching contacts from a single compatible operator. This makes it particularly useful for industrial control circuits requiring multiple contacts to open when the associated pilot device is actuated.
Designed for ABB's modular plastic pilot-device range, the assembly features silver contacts, screw terminals and front mounting. Its compact three-position holder simplifies panel assembly by combining the holder and three contact blocks into one ready-configured component.

Three Normally Closed Contacts for Industrial Control Circuits
Contact blocks convert the mechanical movement of a pushbutton, selector switch or other operator into electrical switching signals. The MCBH-03 provides three normally closed contacts, allowing three control paths to remain closed in their normal state and open when the associated operator is actuated.
By combining all three contacts with a single three-position holder, the ABB MCBH-03 simplifies component selection and installation. Its modular format, silver contacts and industrial electrical ratings make it suitable for machine builders, automation systems and control panels using ABB's 22 mm modular plastic pilot-device platform.
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.
- Multi-contact signalling and control functions.
