Reliable Auxiliary Switching for Industrial Control
Auxiliary contact blocks such as the ABB MACN211AR allow a contactor to provide additional electrical signals independently of its main power contacts. These contacts can be incorporated into control, interlocking, indication and status-monitoring circuits, helping designers build more capable industrial control systems without adding separate relays for every auxiliary function.
The MACN211AR is specifically designed for front mounting on compatible ABB MC1 and MC2 mini contactors. Its combination of one normally open and one normally closed contact provides flexibility for applications such as electrical interlocking, contactor status indication, control sequencing and PLC signalling.
Typical Applications
- Industrial control and automation panels.
- Motor starter and contactor control circuits.
- Electrical interlocking systems.
- Contactor status and position signalling.
- PLC and machine control interfaces.
- OEM machinery and production equipment.
