Why Choose the ABB 1SDA104823R1 AUE XT7 Early Contacts in Closing?
The ABB 1SDA104823R1 is a genuine AUE early auxiliary contact accessory designed for ABB SACE Tmax XT7 moulded-case circuit breakers. Supplied as the AUE XT7 early contacts in closing, it incorporates two early microswitch contacts that operate during the circuit breaker closing sequence, providing dedicated control functionality for compatible XT7 installations.
The primary purpose of the AUE closing contacts is to allow an undervoltage release to be energised before the circuit breaker's main contacts close. This sequencing supports applications where the undervoltage release must receive its supply in advance of main-contact closure, providing coordinated operation within the circuit breaker control system.
The 1SDA104823R1 provides two changeover (SPDT) auxiliary contacts and is designed specifically for the ABB SACE Tmax XT7 platform. With compliance to IEC 60947-2 and UL 489, the accessory is suitable for industrial switchboards, power distribution equipment and automation systems requiring early-contact operation during circuit breaker closing.

Controlled Closing for ABB Tmax XT7 Circuit Breakers
Early auxiliary contacts are mechanically sequenced so that their electrical state changes before the circuit breaker's main contacts complete the corresponding operation. In closing applications, this enables associated control equipment to be activated before current begins flowing through the main power contacts.
The ABB 1SDA104823R1 is specifically designed to allow the undervoltage release of a compatible XT7 circuit breaker to be supplied before main-contact closure. This makes the accessory useful in engineered switchboards and automated power distribution systems where controlled sequencing of the circuit breaker and its release equipment is required.
Typical Applications
- ABB SACE Tmax XT7 moulded-case circuit breaker installations.
- Undervoltage release control circuits.
- Industrial switchboards and power distribution panels.
- Circuit breaker closing-sequence control.
- Automated low-voltage power distribution systems.
- OEM switchgear and industrial electrical assemblies.
