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.
