Why Choose the ABB AUX 3Q 400Vac + 3Q 24Vdc E2.2...E6.2 W?
The ABB 1SDA123750R1 AUX 3Q 400Vac + 3Q 24Vdc E2.2...E6.2 W is a dedicated auxiliary contact block for withdrawable ABB SACE Emax 2 air circuit breakers. Designed for E2.2 through E6.2 frame sizes, it provides auxiliary changeover contacts for signalling the open or closed position of the circuit breaker to external control, indication and automation systems.
The accessory combines three changeover auxiliary contacts rated for circuits up to 400 V AC with three changeover auxiliary contacts for circuits up to 24 V DC. This mixed-voltage arrangement enables a single auxiliary contact assembly to provide circuit breaker status information to different control and signalling circuits within the electrical installation.
The W designation identifies this version for withdrawable Emax 2 E2.2, E4.2 and E6.2 circuit breaker configurations. As a genuine ABB electrical accessory, the 1SDA123750R1 provides purpose-designed integration with the Emax 2 platform for switchboards requiring reliable remote status indication and control-system feedback.
