That SCCR is what lets you coordinate it with upstream protection and avoid cascading failures. At 690 V the interrupting capacity drops to 4 kA — still useful for most 690 V motor circuits, but you need to check the available fault current at that voltage. The 45 mm width (three module spaces on a DIN rail) and 97 mm depth mean it fits standard 35 mm DIN rail enclosures with the screw and snap-on mounting per DIN EN 60715. Spring-loaded terminals on the main current circuit accept 2x 0.5 to 4 mm² solid or stranded — no ring lugs needed, which speeds up panel wiring. Mounting position is any — vertical, horizontal, flat — so you are not constrained by orientation in a crowded enclosure. The 106 mm height and 45 mm width let you pack several of these side by side on a DIN rail. The screw and snap-on fastening means you can clip it onto the rail without tools, then secure with a screw if vibration is a concern. Operating temperature range is -20 to +60 °C, storage -50 to +80 °C, so it handles typical industrial panel conditions without derating concerns in most environments.","metaTitle":"Siemens 3RV2311-1EC20 SIRIUS Circuit Breaker, 100 kA SCCR","metaDescription":"Siemens 3RV2311-1EC20 SIRIUS circuit breaker for starter combinations. 100 kA SCCR at 400 V, 45 mm wide, spring-loaded terminals.
