Schneider Auxiliary Switch OF or SD 1 C-O (MCCB)

The Schneider Electric Auxiliary Switch (OF or SD) – 1 C-O is a high-quality optional accessory designed to enhance the functionality and monitoring capabilities of Moulded Case Circuit Breakers (MCCBs). Specifically engineered for use with NSX 100-250, NSX 400-630, NS800-NS1600 MCCBs, this auxiliary switch plays a crucial role in signaling circuit breaker status to external monitoring systems.

The "OF" (Open/Closed) auxiliary switch provides a clear indication of whether the breaker is in the ON or OFF position, ensuring effective remote monitoring and system integration. On the other hand, the "SD" (Trip Indication) auxiliary switch detects and signals when the breaker has tripped due to a fault, allowing for quick response and system diagnostics.

Built with robust and reliable components, the Schneider Electric Auxiliary Switch ensures high durability and seamless operation under various electrical conditions. This compact, easy-to-install accessory significantly improves operational safety, maintenance efficiency, and overall system protection by offering real-time breaker status feedback.

Ideal for industrial, commercial, and power distribution applications, this auxiliary switch is a valuable addition to any Schneider Electric MCCB system, enabling enhanced control, monitoring, and safety compliance.
