Why Choose the ABB 1SCA162790R1001 AUXGM3-11 Auxiliary Contact Block?
The ABB 1SCA162790R1001 AUXGM3-11 is a genuine auxiliary contact block designed for DIN-mounted ABB OT Plus switch-disconnectors. Providing one normally open and one normally closed contact, it enables dependable switch-position signalling, monitoring, electrical interlocking and control-system integration.
Designed for compatible OT30G3 to OT160G3 switch-disconnectors, the AUXGM3-11 uses a convenient snap-on mounting system and can be installed on either side of the switch. This allows panel builders and electrical engineers to add auxiliary switching functions without modifying the primary switching device.
The normally open contact incorporates an early-break function, allowing the auxiliary circuit to change state before the main contacts complete their opening sequence. A filler component for the DIN cut-out is also included, helping maintain a neat and protected installation within distribution boards and control panels.

Reliable Auxiliary Switching for DIN-mounted Disconnectors
The ABB AUXGM3-11 operates mechanically with the associated OT Plus switch-disconnector, providing additional electrical contacts that respond to the position of the main switch. These contacts can be connected to PLC inputs, indicator lamps, relays, alarms and other monitoring or control equipment.
Its early-break normally open contact is particularly useful where a control circuit must change state shortly before the main contacts open. This supports controlled switching sequences, advance status indication and dependable electrical interlocking in industrial power-distribution applications.
Typical Applications
- DIN-mounted switch-disconnector installations.
- Industrial distribution boards.
- Machine control and automation systems.
- PLC switch-position monitoring.
- Electrical interlocking circuits.
- Motor control centres.
- OEM control-panel assemblies.
