Branch Circuit Protecon (BCP)
Short Circuit Current Rangs (SCCR) with Standard Fuses and Circuit Breaker
(Tested per UL61800-5-1, reference UL le E132659)
These devices are suitable for motor group installaon when used with Standard Fuses and Circuit Breaker.
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.
