Why Choose the ABB 1SAL103354R9906 MARN422AR Auxiliary Contact?
The ABB 1SAL103354R9906 (MARN422AR) is a compact and reliable front-mounted auxiliary contact block designed for switching auxiliary and control circuits in industrial automation applications. Featuring 2 normally open (NO) and 2 normally closed (NC) contacts, it provides four additional instantaneous contacts for expanding the control and signalling capabilities of compatible ABB mini contactors and mini contactor relays.
As part of ABB's M mini contactor accessory range, the MARN422AR is designed for front mounting on ABB MCR mini contactor relays and MC1 and MC2 mini contactors. Its clip-on construction provides straightforward installation, while the four-pole contact arrangement makes it particularly useful for electrical interlocking, status indication, control sequencing and other auxiliary circuit functions.
The MARN422AR uses ring tongue terminal connections for secure industrial wiring and has contacts designated in accordance with EN 50005. With a conventional free-air thermal current of 10 A and a rated operational current of 6 A at 230 V AC in AC-15 applications, it provides dependable switching performance for industrial control circuits.

Reliable Auxiliary Switching for Industrial Control
Auxiliary contact blocks such as the ABB MARN422AR expand a contactor or contactor relay with additional electrical contacts for control and signalling purposes. These contacts can be incorporated into interlocking, indication, sequencing and monitoring circuits, enabling more sophisticated machine control without requiring separate switching devices for every auxiliary function.
The MARN422AR provides two normally open and two normally closed instantaneous contacts in a compact front-mounted assembly. Its compatibility with ABB MCR mini contactor relays and MC1 and MC2 mini contactors makes it a practical accessory for machine builders, panel builders and automation engineers requiring additional control contacts while maintaining a compact installation.
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.
