Why Choose the ABB AUX 1SY 24V DC XT7 1SDA104812R1 Auxiliary Contact?

The ABB 1SDA104812R1 is a genuine auxiliary contact for ABB SACE Tmax XT7 circuit breakers, designed to provide electrical indication when the associated circuit breaker has tripped. ABB identifies the accessory as AUX 1SY 24V DC XT7, providing a dedicated SY contact for remote trip-status signalling.

The accessory incorporates one SPDT changeover contact and is intended for signalling circuits operating below 24 V DC. This allows the trip condition of a compatible XT7 circuit breaker to be communicated to external indication, alarm, PLC or supervisory control equipment without relying on local visual inspection.

As an original ABB SACE Tmax XT electrical accessory, the 1SDA104812R1 is purpose-designed for the XT7 platform and uses a spring-clamp electrical connection. It is specified to IEC 60947-2 and UL 489, is RoHS compliant and has a product net weight of 0.127 kg, making it a compact solution for low-voltage trip signalling applications.

Low-Voltage Trip Status Signalling for ABB XT7 Circuit Breakers

Auxiliary trip contacts allow circuit breaker operating information to be transmitted to external equipment automatically. The SY contact in the ABB 1SDA104812R1 provides an electrical indication associated with the tripped condition, enabling remote supervision of a compatible SACE Tmax XT7 circuit breaker.

Designed for circuits below 24 V DC, this auxiliary contact is particularly suited to low-voltage control and monitoring systems. Its changeover contact can be incorporated into PLC inputs, switchboard annunciation, alarm circuits and supervisory systems where reliable indication of a circuit breaker trip is required.

Typical Applications

  • Remote trip indication for ABB SACE Tmax XT7 circuit breakers.
  • 24 V DC PLC and automation input circuits.
  • Low-voltage switchboard alarm and indication circuits.
  • Electrical distribution monitoring systems.
  • Building management and supervisory control systems.
  • Industrial and commercial power distribution panels.
