ABB Auxiliary Changeover Contact Accessory 24VDC Coil Voltage for Tmax XT Circuit 1SDA066449R1 AUX-C 3Q+1SY 24VDC XT2-XT4

ABB 1SDA066449R1 AUX-C 3Q+1SY 24VDC XT2-XT4 Auxiliary Changeover Contact is a specialized accessory designed to expand signalling capabilities of Tmax XT withdrawable circuit breakers. It provides additional functionality for industrial, electrical, and automation applications.

The accessory includes a combination of three changeover contacts used for distinct open/closed circuit breaker status signalling, plus one dedicated changeover contact for tripped condition monitoring. These contacts operate on a 24VDC coil voltage, enabling seamless integration into low-voltage control schemes common in industrial and commercial setups.

Meeting IEC 60947-2 standards, this product ensures reliable and standardized interaction within modular SACE Tmax installations specifically optimized for the XT2 and XT4 withdrawable breaker range. Its robust design suits use in industrial electrical panels, control cabinets for machine automation, and electrical distribution systems requiring accurate and prompt alarm signalling and interlock logic implementation.

The product enables effective remote monitoring by signalling the open, closed, and tripped states distinctly, facilitating maintenance and operational safety. It is essential for integrating advanced control measures in industrial electrical infrastructures.

Three changeover contacts provide separate indication for open and closed statuses. An additional changeover contact signals the tripped condition independently. 24VDC coil voltage supports low-voltage control circuit compatibility.

Compliance with IEC 60947-2 ensures accessory reliability and safety. Designed for use with Tmax XT2 and XT4 withdrawable breakers. Ideal for industrial electrical panels and machine automation control cabinets. Enables remote status monitoring and interlock functions in electrical distribution.

This ABB auxiliary contact is manufactured in Italy, representing high-quality European engineering standards. It is suitable for professional electricians and engineers involved in industrial automation, electrical maintenance, and control system design.
