Description

The ABB MCBH-10 is a rear-mount modular contact block providing one normally open (N.O.) contact for use with ABB M2 series pushbutton components, forming part of the MCBH stacking contact block family. Compatible with the MCBH-00 holder and other MCBH contact blocks, it enables multi-output operator assemblies to be constructed for complex switching and signalling requirements in industrial control circuits. Rated to IEC 60947-5-1, the MCBH-10 provides a reliable N.O. contact output for start commands, run indication, enable signals, and PLC input connections.

The MCBH-10 is rated for AC-15 and DC-13 utilisation categories per IEC 60947-5-1 and uses screw terminal connections for reliable wiring. Its N.O. contact closes when the pushbutton is pressed, generating a momentary or maintained switching signal depending on the actuator type, and is suitable for direct circuit switching or as a PLC digital input signal. Multiple MCBH contact blocks can be stacked together using the MCBH-00 holder to create operator devices with a combination of N.O. and N.C. contacts matching complex circuit requirements.

As part of ABB’s M2 modular operator component range, the MCBH-10 contributes to the construction of professional, flexible operator interface assemblies. Panel builders and machine builders use it where a single M2 actuator must provide more than one switching output simultaneously, reducing panel space requirements and avoiding the need for auxiliary relay circuits. The MCBH-10 is widely used in motor control panels, industrial machinery, process automation systems, and building services control panels where compact, multi-function operator devices are needed.
