Depth is 97 mm, height 106 mm. Spring-loaded terminals on the main current circuit accept 2x 0.5 to 4 mm² solid or stranded conductors — no lug torqueing, just strip to 8 mm and push in. ## Coordination with upstream protection For selective coordination with a feeder breaker or fuse, the 3RV2311-1CC20 requires a gL/gG backup fuse sized at 25 A for 400 V and 500 V systems, and 20 A at 690 V. That fuse is not included — it's the upstream device that ensures the breaker's 100 kA SCCR is maintained. If you're replacing a 3RV2011-0BA20 in an existing panel, check the fuse sizing: the 3RV2011-0BA20 may have different backup requirements. The 3RV2311-1CC20's spring-loaded terminals also differ from the screw terminals on the 3RV2011-0BA20, so verify the conductor type and ferrule compatibility before swapping.","metaTitle":"Siemens 3RV2311-1CC20 SIRIUS Circuit Breaker, 100 kA at 400","metaDescription":"Siemens 3RV2311-1CC20 SIRIUS circuit breaker for starter combinations. 100 kA SCCR at 400 V AC, spring-loaded terminals, DIN rail mount.
