The Switching Control Sentinel (SCS) is a microprocessor-based control device, which enables synchronized closing or opening of independent pole operated (IPO) circuit breakers. Housed in a NEMA 1 enclosure, the SCS is installed as a modular component in the control cabinet of the circuit breaker at the factory.
Any model can be used for any synchronous closing or opening application by means of configuration and external wiring. A bypass circuit, providing ganged breaker operation in case of loss of DC power, can be enabled or disabled via an external jumper.
The current firmware version is 3.55, Build 14.
