Short-circuit current limiter 3-pole 63A 600VAC - Current limiter 43470VA S803W-SCL63-SR – ABB – 2CCS803917R0599 – 7612271425661: Short-circuit current limiter 3-pole 63A 600VAC S803W-SCL63-SR Number of auxiliary contacts as NC contact 0 Number of auxiliary contacts as NO contact 0 Number of auxiliary contacts as changeover contact 0 Number of poles 4 The short-circuit current limiter of the S800 series increases the short-circuit breaking capacity of the downstream switching devices. A distinction must be made between the SCL and the SCL-SR devices. The latter are self-resetting devices. The advantage of this self-resetting S800-SCL-SR short-circuit current limiter is that a continuous flow of current to all downstream switching devices is guaranteed, which simplifies group protection. Up until now, a separate short-circuit current limiter was used with the S800SCL devices for each feeder, in order to be able to ensure that, in the event of a fault, all the other branches apart from the faulty branch continue to work. This is no longer necessary - now you can protect a whole group of motor protection switches / high-performance circuit breakers with just one S800-SCL-SR. Can only be used for permitted combinations.
