Branch Circuit Protection
Integral solid-state short circuit protection does not provide Branch Circuit Protection. Branch Circuit Protec
-
tion must be provided in accordance with the National Electrical Code (NEC) and applicable local codes or
equivalent as determined by Authorities Having Jurisdiction (AHJ). The drive shall be protected by Listed
Class J fuses, listed inverse-time circuit breakers, or Franklin Electric Manual Motor Starters.
Short-circuit current rating (SCCR): The drive is suitable for use on a circuit capable of delivering no more
than 100,000 symmetrical amperes (rms) when protected by suitable Class J fuses. For rated fuse currents,
refer to NEC Sec 430 and the Franklin Electric AIM Manual. When protected by a circuit breaker and placed
in a panel, drive SCCR is as follows:
Fuse and Circuit Breaker Sizing
