4.4 Using residual current protective devices (RCD)
Residual current protective devices must be installed if the loop impedance at the line
connection point is so high that in the case of a phase-ground short-circuit, the overcurrent
protective devices do not trip within the specified time.
Conditions for using residual current protective devices
● Super-resistent (short time-delayed) universal current-sensitive RCDs, type B
● Rated fault current, 300 mA
● Separate RCD for each Power Module
Recommendation for PM240-2, FSA-FSD 200 V and 400 V:
Siemens SIQUENCE ground-fault circuit interrupter (RCCB) 5SM3 type B
Recommendation for PM240-2, FSE-FSF 200 V, FSE-FSG 400 V as well as FSD-FSG
690 V:
Siemens modular residual current protective device (MRCD) 5SV81 type B in conjunction
with Siemens 3VA1 circuit breakers
