Why Choose the ABB MCB-02G Gold-Plated Contact Block?
The ABB MCB-02G, supplied under ABB order code 1SFA611610R1120, is a double normally closed contact block with gold-plated contacts for ABB modular plastic pilot devices. It provides a 2 NC contact configuration for industrial control and signalling circuits where dependable low-level switching performance is required.
The MCB-02G is designed for ABB 3-position and 5-position holders, allowing it to be combined with compatible pushbuttons, selector switches and other modular operators. Its two normally closed contacts remain closed in the normal state and open when actuated by the associated operator.
The gold-plated contact surfaces distinguish the MCB-02G from ABB's standard MCB-02 contact block and make it particularly suitable for low-current and electronic signalling circuits. Screw-terminal connections provide practical and secure field wiring within industrial control panels.
Key Advantages
- 2 NC contact configuration provides two normally closed switching circuits in one block.
- Gold-plated contacts support reliable switching of low-current control and signalling circuits.

Gold-plated contacts are particularly useful in control circuits operating with low currents or signal levels, where maintaining a clean and dependable electrical contact surface is important. The ABB MCB-02G combines this contact technology with two normally closed switching paths in a compact modular contact block.
Designed for ABB's 3-position and 5-position holders, the MCB-02G can be incorporated behind compatible modular pilot-device operators to provide the required electrical switching function. Its combination of gold-plated contacts, screw terminals and industrial electrical ratings makes it suitable for machinery, automation and electronic control interfaces.
Typical Applications
- Industrial pushbutton assemblies.
- Selector-switch control circuits.
- Low-current control and signalling circuits.
- PLC and electronic control interfaces.
- Automation and production equipment.
- Machine and process control panels.
- OEM machinery and operator stations.
