The integral solid state protection does not provide branch circuit protection
and that branch circuit protection has to be provided externally in
accordance with manufacturers instructions, the National Electrical Code
and any additional codes.
Branch circuit protection (240 V devices)
Suitable for use on a circuit capable of delivering not more than:
– 5000 rms symmetrical amperes, 240 V maximum (240 V devices).
– 200k rms symmetrical amperes, 240 V maximum when protected by
CC, J, T or R class fuses.
– 50k rms symmetrical amperes, 240 V maximum when protected by a
circuit breaker having an interrupting rating not less than 50k rms
symmetrical amperes, 240 V maximum.
Branch circuit protection (400 V/500 V devices, 0.37 ... 22 kW)
Suitable for use on a circuit capable of delivering not more than:
– 5000 rms symmetrical amperes, 400 V/500 V maximum.
– 200k rms symmetrical amperes, 500 V maximum when protected by
CC, J, T or R class fuses.
– 50k rms symmetrical amperes, 500 V maximum when protected by a
circuit breaker having an interrupting rating not less than 50k rms
symmetrical amperes, 480 V/277 V
Branch circuit protection (400 V/500 V devices, 30 ... 45 kW)
Suitable for use on a circuit capable of delivering not more than:
– 10k rms symmetrical amperes, 500 V maximum, when protected by
CC, J or T class fuses.
– 200k rms symmetrical amperes, 500 V maximum when protected by
CC, J or T class fuses.
Branch circuit short circuit protection with fuses in accordance with UL248
or circuit breaker, 400 V/480 V
Voltage of the fuses or circuit breakers must at least be suitable with the
input voltage of the drive. The specific fuse/circuit breaker sizes and classes
for each inverter are shown in the table below.
