Why Choose the ABB MARN211AT 1SAL100993R9906 Auxiliary Contact?
The ABB MARN211AT 1SAL100993R9906 is a compact and reliable two-pole auxiliary contact block designed for switching auxiliary and control circuits in standard industrial environments. Featuring 1 normally open (NO) and 1 normally closed (NC) contact, it provides additional switching contacts for signalling, interlocking and machine control functions.
Designed for front mounting, the MARN211AT uses screw terminals to provide secure electrical connections. It is suitable for front mounting on ABB MCR miniature contactor relays and MC1 and MC2 miniature contactors, while its auxiliary contacts meet the requirements of EN 50005.
With a conventional free-air thermal current of 10 A and a rated operational current of 6 A at AC-15, 230 V, the MARN211AT is suitable for industrial auxiliary and control circuit applications. Its compact 27 × 45 × 35 mm dimensions help minimise the installation space required within electrical control panels and machinery.
Key Advantages
- Compact two-pole auxiliary contact block for industrial control circuits.
- 1NO/1NC contact configuration for flexible signalling and interlocking.
- Front-mounted design for straightforward installation.
- Secure screw terminal connections.
- 6 A rated operational current at AC-15, 230 V.
- Auxiliary contacts meet the requirements of EN 50005.
Key Features
- ABB MARN211AT auxiliary contact block.
- 1 normally open and 1 normally closed contact.
- 10 A conventional free-air thermal current.
- 6 A rated operational current at AC-15, 230 V.
- Front-mounted configuration.
- Screw terminal electrical connections.
- 0.8 N·m auxiliary circuit tightening torque.
- Maximum permitted operating altitude of 3000 m.
Reliable Auxiliary Control for Industrial Applications
Auxiliary contact blocks provide additional switching contacts for control, signalling and interlocking functions within electrical control systems. They allow contactor operating states and control signals to be incorporated into machine logic without using the main power contacts for auxiliary switching duties.
The ABB MARN211AT combines one normally open and one normally closed auxiliary contact in a compact front-mounted format. Its 1NO/1NC configuration provides flexibility for applications requiring complementary contacts for control logic, status indication and electrical interlocking.
Typical Applications
- Industrial auxiliary and control circuits.
- Contactor status signalling.
- Electrical interlocking circuits.
- Machine control panels.
- Industrial automation systems.
- Motor control and switching assemblies.
