ABB Stotz-Kontakt S803S-SCL-100-SR short-circuit current limiter, 2CCS803901R0639

The S800-SCL-SR can be used together with the high-performance circuit breaker S800S or motor protection switches. The S800-SCL-SR limits the short-circuit current and helps to extinguish it until the switching device closest to the fault trips. During this entire time, the flow of current to the downstream switching devices is ensured, which makes it the ideal solution for group protection. This is because, apart from the faulty outgoing circuit, all other parallel outgoing circuits remain in operation.
