What are the values of the 1P breaking capacities of GV2P circuit-breakers in IT earthing system?

The values below are the breaking capacities of GV2P circuit-breakers operating on an IT earthing system at 400 V 50 Hz, as demonstrated by pole-by-pole tests carried out in Schneider Electric laboratories:

• GV2P only

GV2P01 to GV2P07:          0.1 to 2.5 A          Breaking capacity: 25.0 kA
GV2P08:                               2.5 to 4.0 A         Breaking capacity: 12.5 kA
GV2P10 and GV2P14:     4.0 to 10.0 A         Breaking capacity:  8.0 kA
GV2P16 to GV2P20:         9.0 to 18.0 A        Breaking capacity:   6.0 kA
GV2P21 and GV2P32:    17.0 to 32.0 A        Breaking capacity:  4.5 kA

• GV2P with GV1L3 limiter

GV2P08 to GV2P16:       2.5 to 14.0 A          Breaking capacity: 25.0 kA
GV2P20:                          13.0 to 18.0 A         Breaking capacity:  12.5 kA
GV2P21 to GV2P32:      17.0 to 32.0 A         Breaking capacity:  10.0 kA

• GV2P with LA9LB920 limiter

GV2P21 to GV2P32:       17.0 to 32.0 A         Breaking capacity: 12.5 kA
