AIC, Fuse and Wire sizes
Use the UL listed fuses at connecting to power supply.
Short circuit test is performed under the condition of the power supply short-circuit currents in below.
These interrupting capacities and fuse rating currents depend on the applicable motor capacities.

Suitable for use on a circuit capable of delivering not more than___X___rms symmetrical kilo
Amperes,___Y___Volts maximum, when protected by___Z1___with a maximum rating of___Z2___.
(1) Input withstand rating is that for which the product has been designed thermally. Installation on a
supply greater than this level will require additional inductance to satisfy this level.
(2) Output interrupt rating relies on Integral solid state short circuit protection. This does not provide
branch circuit protection. Branch circuit protection must be provided in accordance with the National
Electrical Code and any additional local codes. This is dependant on the type of installation.
In case of using with a higher AIC capability up to 100kA(*1), the Short Circuit Current Ratings (SCCR)
become 100kA(*1) by installing with the circuit breakers(GV•P) or the fuses listed in Table 4.

(*1) In case with the circuit breaker, the Short Circuit Current Ratings (SCCR) is 65kA.
(*2) The manufacturer of the fuses should be "Cooper Bussmann" or "Mersen" (formerly, "Ferraz
Shawmut") for the compliance of UL standard.
(*3) The manufacturer of the listed circuit breaker is "Schneider Electric".
