Why Choose the ABB MACN422AT 1SAL100996R9906 Auxiliary Contact?
The ABB MACN422AT 1SAL100996R9906 is a compact and reliable four-pole auxiliary contact block designed for switching auxiliary and control circuits in standard industrial environments. Featuring 2 normally open (NO) and 2 normally closed (NC) contacts, it provides a balanced contact arrangement for signalling, interlocking and control functions.
Designed for front mounting, the MACN422AT uses screw terminals to provide secure electrical connections. It is designed for ABB MC1 and MC2 miniature contactors with an integrated normally open auxiliary contact, while its auxiliary contact arrangement meets the requirements of EN 50012.
With a conventional free-air thermal current of 10 A and a rated operational current of 6 A at AC-15, 230 V, the MACN422AT 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, 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 MACN422AT combines two normally open and two normally closed auxiliary contacts in a compact front-mounted format. Its balanced 2NO/2NC configuration provides flexibility for applications requiring both normally open and normally closed signals for control logic, status indication and 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.
