Why Choose the ABB MARN422AT 1SAL100989R9906 Auxiliary Contact?
The ABB MARN422AT 1SAL100989R9906 is a compact and reliable four-pole auxiliary contact block designed for switching auxiliary and control circuits in standard industrial environments. Featuring 2 normally open (NO) and 2 normally closed (NC) contacts, it provides a balanced contact configuration for signalling, interlocking and machine control applications.
Designed for front mounting, the MARN422AT uses screw terminals for secure electrical connections. It is suitable for front mounting on ABB MCR miniature contactor relays and MC1 and MC2 miniature contactors, while its contact designation complies with 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 MARN422AT is well suited to industrial auxiliary and control circuits. Its compact 27 × 45 × 35 mm dimensions help minimise the space required within electrical control panels and machinery.
Key Advantages
- Compact four-pole auxiliary contact block for industrial control circuits.
- 2NO/2NC 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.
- Contact designation compliant with EN 50005.

Reliable Auxiliary Control for Industrial Applications
Auxiliary contact blocks provide additional switching contacts for control, signalling and interlocking functions within electrical control systems. They enable contactor operating states and control signals to be incorporated into machine logic without using the main power contacts for auxiliary switching duties.
The ABB MARN422AT combines four auxiliary contacts in a compact front-mounted format. Its balanced 2NO/2NC configuration provides flexibility for applications requiring both normally open and normally closed signals 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.
