Short Circuit Current Ratings (SCCR) with Standard Fuses and Circuit Breaker
(Tested per UL61800-5-1, reference UL file E132659)
These devices are suitable for motor group installation when used with Standard Fuses and Circuit Breaker.
For single motor installation, 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 ratings, the nearest standard
ratings less than the calculated value shall apply.
