Why Choose the ABB MARN440AT 1SAL100991R9906 Auxiliary Contact?
The ABB MARN440AT 1SAL100991R9906 is a compact and reliable four-pole auxiliary contact block designed for switching auxiliary and control circuits in standard industrial environments. Featuring 4 normally open (NO) contacts, it provides additional switching contacts for signalling, control and automation functions.
Designed for front mounting, the MARN440AT uses screw terminals to provide secure electrical connections. The auxiliary contact is suitable for ABB MCR miniature contactor relays and is designed with contacts in accordance with EN 50005, supporting integration into industrial control systems.
With a conventional free-air thermal current of 10 A and a rated operational current of 6 A at AC-15, 230 V, the MARN440AT is suitable for demanding auxiliary and control circuit applications. Its compact 27 × 45 × 35 mm dimensions make it well suited to space-conscious 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 MARN440AT combines four normally open auxiliary contacts in a compact front-mounted format. Its 4NO configuration is particularly useful where several normally open signals are required for control logic, status indication or 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.
