S803S-SCL
Short-circuit current limiter
The S803S used together with an S803S-SCL ensures reliable switch-off of short-circuit
currents up to 100 kA, at an operating voltage of 440 V AC and over the entire rated current
range of up to 125 A.
For applications at 690 V AC, the combination of S803S-SCL ensures reliable short-circuit
protection up to 50 kA; here also, this is ensured over the entire rated current range up to
125 A, typical for the S800.
