Reliable Auxiliary Signalling for Switch-Disconnectors

Auxiliary contacts such as the ABB OA1G01 are used to provide remote electrical feedback from switchgear. When fitted to a compatible switch-disconnector, the contact can indicate whether the switch is in an open or closed position, supporting safer operation and clearer system monitoring.

The OA1G01 is especially useful in control panels where switch position needs to be connected to control circuits, warning lights, PLC inputs or interlocking systems. Its compact format and ABB switchgear compatibility make it a practical accessory for industrial isolation and distribution assemblies.

Typical Applications

• ABB OT switch-disconnector assemblies.
• Industrial control panels and electrical cabinets.
• Switchgear status indication circuits.
• PLC input and automation signalling.
• Electrical interlocking systems.
• Motor control panels and machinery isolation systems.
• Power distribution and low voltage switching applications.

Trusted for ABB Switchgear Control

ABB auxiliary contacts are widely used in industrial switchgear, control panels and low voltage power distribution systems to support reliable status indication, control signalling and safe electrical interlocking.
