Reliable Auxiliary Signalling for ABB Switch-Disconnectors
Auxiliary contacts allow a switch-disconnector to provide additional electrical signals independently of its main power contacts. These signals can be incorporated into control, status indication, interlocking and monitoring circuits so that other equipment can respond to the operating state of the switching system.
The ABB OA1G01AU combines a 1NC configuration with gold-plated contacts for applications involving demanding conditions and low voltages. Its snap-on mounting arrangement provides straightforward integration with compatible ABB OT switch-disconnectors while maintaining a compact installation.
Typical Applications
- Switch-disconnector position signalling.
- Industrial control and monitoring circuits.
- Electrical interlocking systems.
- Low-voltage signalling circuits.
- Switchgear and distribution panels.
- Industrial automation and control cabinets.
