Coordination Type Rating at 400 V Rating at 690 V

Type 1 Coordination 250 A gG/gL 100 A gG/gL 

Type 2 Coordination 125 A gG/gL 80 A gG/gL 

UL/CSA Short-Circuit Current Ratings (SCCR):

Basic rating: 10 kA at 250 A max fuse/CB 

High fault at 480 V: 100 kA with 150 A Class J fuse 

High fault at 600 V: 100 kA with 150 A Class J fuse 

4. Robust Switching Capacity

Rated Breaking Capacity: 650 A at 220/230 V, 380/400 V, and 500 V 

Rated Making Capacity: 910 A up to 690 V 

Switching Time (AC operated): Closing delay 12-18 ms, opening delay 8-13 ms
