Why Choose the ABB MCB-10BG Contact Block?
The ABB MCB-10BG is a modular single normally open (1 NO) contact block with gold-plated contacts designed for dependable switching in industrial pilot-device and control applications. Part of the ABB Modular pilot device range, it is particularly suited to low-level control and signalling circuits where reliable contact performance is important.
The MCB-10BG uses a 1 NO contact configuration, providing a normally open circuit that changes state when mechanically actuated by the associated operator or mounting arrangement. Its gold-plated contact surfaces provide enhanced suitability for low-current and low-voltage switching applications compared with conventional contact materials.
Designed for rear mounting, the MCB-10BG can be used with compatible ABB pilot-device installations, MEP plastic enclosures or DIN-rail arrangements. Its compact construction, 690 V rated insulation voltage, IP20 terminal protection and long mechanical durability make it a practical contact solution for industrial machinery and automation control circuits.

Reliable Gold-Plated Contact Switching for Control Circuits
Contact blocks translate mechanical actuation into an electrical switching function within machinery and automation control circuits. The ABB MCB-10BG provides one normally open contact, which remains open in its normal condition and closes when the contact block is mechanically actuated.
The gold-plated contact surfaces make the MCB-10BG particularly useful where dependable switching of low-level signals is required. Its compact rear-mounted construction also allows integration into compatible ABB pilot-device, enclosure and DIN-rail installations while maintaining a space-efficient control-panel layout.
Typical Applications
- Industrial pilot-device control circuits.
- Low-level signalling and switching circuits.
- Machine-control panels.
- Industrial operator stations.
- MEP plastic enclosure assemblies.
- DIN-rail control arrangements.
- Production and packaging machinery.
- OEM automation and machine-building systems.
