Why Choose the ABB MCBH-30 Block Holder with Contact Blocks?
The ABB MCBH-30, supplied under ABB order code 1SFA611605R1103, is a three-position block holder supplied with three normally open contact blocks for ABB modular plastic pilot devices. It provides a convenient pre-assembled switching solution for industrial pushbuttons, selector switches and other compatible non-illuminated operator devices.
The MCBH-30 combines the three-position holder and three 1 NO contact blocks in a single assembly, reducing the number of individual components required during panel assembly. The contacts use screw terminals and are rated for demanding industrial control duties, including AC-15 6 A at 230 V AC.
Designed for ABB's 22 mm modular plastic pilot-device range, the MCBH-30 mounts behind a compatible front operator and provides three independent normally open switching contacts. Its modular construction makes it well suited to machinery, automation systems and industrial control-panel applications requiring multiple simultaneous control contacts.
Key Advantages
- Holder with three contact blocks supplied as one convenient assembly.
- 3 NO contact configuration provides three normally open control contacts.
- Three-position holder accommodates the included contact blocks in a compact arrangement.

- Screw-terminal connections provide secure field wiring.
- Designed for ABB's 22 mm modular plastic pilot devices.
- Suitable for front-mounted, non-illuminated pilot-device assemblies.
Key Features
- ABB MCBH series holder and contact-block assembly.
- Three-position holder.
- Three normally open contacts.
- Zero normally closed contacts.
- Front fastening.
- Screw connections.
- AC-15 operational current: 6 A at 230 V AC.
- Rated insulation voltage: 690 V.
- Rated impulse withstand voltage: 6 kV.
- Mechanical life: up to 10 million operations.
- Designed for 22 mm pilot devices.
- Non-illuminated configuration with no lamp holder.
Three Normally Open Contacts in a Compact Modular Assembly
Pilot-device contact blocks translate the mechanical movement of a pushbutton, selector switch or other operator into electrical control signals. With three normally open contacts, the MCBH-30 can provide multiple switching paths from a single compatible operator, making it useful where several control circuits or signals need to be operated together.
By supplying the contact blocks already combined with a three-position holder, ABB simplifies component selection and panel assembly. The MCBH-30's screw terminals, industrial AC-15 rating and modular format make it suitable for machine builders, panel builders and automation systems using ABB's 22 mm modular plastic pilot-device platform.
Typical Applications
- Industrial pushbutton assemblies.
- Selector-switch control circuits.
- Machinery control panels.
- Automation and production equipment.
- Motor-control and process-control panels.
- OEM machinery and operator stations.
- Multi-contact signalling and control functions.
