Why Choose the ABB MARN220AT 1SAL100994R9906 Auxiliary Contact?
The ABB MARN220AT 1SAL100994R9906 is a compact and reliable two-pole auxiliary contact block designed for switching auxiliary and control circuits in standard industrial environments. Featuring 2 normally open (NO) contacts, it provides additional switching contacts for signalling, control and automation functions.
Designed for front mounting, the MARN220AT 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 MARN220AT 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.

Reliable Auxiliary Control for Industrial Applications
Auxiliary contact blocks provide additional switching contacts for control and signalling 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 MARN220AT combines two normally open auxiliary contacts in a compact front-mounted format. Its 2NO configuration is particularly useful where additional normally open signals are required for control logic, status indication and other auxiliary circuit functions.
Typical Applications
- Industrial auxiliary and control circuits.
- Contactor status signalling.
- Machine control panels.
- Industrial automation systems.
- Motor control circuits.
- Industrial switching assemblies.
