Why Choose the ABB MACN431AT 1SAL100995R9906 Auxiliary Contact?
The ABB MACN431AT 1SAL100995R9906 is a compact four-pole auxiliary contact block designed for switching auxiliary and control circuits in industrial applications. Featuring 3 normally open (NO) and 1 normally closed (NC) contacts, it provides additional switching capacity for signalling, interlocking and control functions.
The MACN431AT is designed for front mounting on ABB MC1 and MC2 miniature contactors and uses screw terminals for secure electrical connections. Its auxiliary contact arrangement is in accordance with EN 50012, supporting standardised integration into industrial control and automation systems.
With a conventional free-air thermal current of 10 A and four auxiliary contacts, the MACN431AT provides a practical way to expand the control functionality of compatible ABB miniature contactors. Its compact 27 × 45 × 35 mm dimensions help minimise space requirements within electrical control panels and machinery.

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 the operating state of a contactor to be incorporated into machine logic while keeping auxiliary switching functions separate from the main power contacts.
The ABB MACN431AT combines three normally open contacts and one normally closed contact in a compact front-mounted format. Its 3NO/1NC arrangement is well suited to applications requiring several normally open signals together with a normally closed contact for control logic, status indication or 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.
