Reliable Status Signalling for Tmax XT Circuit Breakers

Auxiliary contact accessories such as the ABB AUX 1Q 250Vac/dc XT1...XT6 are used to provide electrical feedback from circuit breakers to external control and monitoring systems. This allows operators and automation systems to identify whether a breaker is open or closed without needing to inspect the breaker manually.

The ABB 1SDA066422R1 helps improve system visibility in low-voltage switchgear, distribution boards and automated control panels. By adding open-closed position indication to compatible Tmax XT circuit breakers, it supports faster diagnostics, improved control feedback and more effective electrical system supervision.

Typical Applications

• ABB SACE Tmax XT circuit breaker assemblies.
• Low-voltage switchgear and distribution panels.
• Breaker open and closed status indication.
• Control panel signalling and monitoring circuits.
• PLC and automation system feedback circuits.
• Industrial maintenance, retrofit and panel building applications.
