Why Choose the ABB 1SCA162594R1001 Auxiliary Contact Block?

The ABB 1SCA162594R1001 is a genuine auxiliary contact block developed for the ABB OT Plus switch-disconnector series. Featuring one normally open (1NO) and one normally closed (1NC) contact, it provides reliable signalling and control functions for industrial switch-disconnectors used in power distribution, automation and control systems.

Designed for base-mounted OT16G to OT160G switch-disconnectors, this auxiliary contact snaps securely onto either side of the switch without the need for complex installation procedures. The normally open contact incorporates an early-break function, making it ideal for safety and interlocking applications where signalling must occur before the main contacts open.

Manufactured to ABB's high quality standards, the 1SCA162594R1001 improves the functionality of OT Plus switch-disconnectors by enabling remote indication, PLC feedback and control circuit integration, making it an excellent choice for panel builders, OEMs and industrial maintenance engineers.
