GCP-3XYZ B- ABC-SCxx

X = 1 = Generator Circuit breaker                    X= 2  = Generator and Mains breaker                    X = 0 = no breaker 

Y = 1 = 100 VAC voltage sensing                      Y = 4 = 400 VAC voltage sensing

Z = 1   = ../1A current sensing                              Z =5 =../5A  current sensing

B = flush mounting
