Required protective devices
If ELCB breakers are prescribed to protect the input connections, consider the high leakage current
towards the earth generated by the noise-suppressor capacitors.
If strongly prescribed, the ELCB breakers should be the largest type suitable for non-linear current and
for delayed operation.
