Short Circuit Current Rangs (SCCR) with Semiconductor Fuses
(Tested per UL61800-5-1, reference UL le E132659)
These devices are suitable for standard installaon when used with Semiconductor Fuses. For single motor
installaon, if the fuse value indicated is higher than 400 % of the motor current (FLA), the fuse value has to
be calculated. If the value of the fuse is below two standard rangs, the nearest standard rangs less than
the calculated value shall apply.
