The 45 mm width is a standard 2.5 module footprint on a DIN rail — useful when estimating fill factor on a panel's gland plate. Clearance requirements: 50 mm upward and downward, 30 mm to the side, and zero forward or backward clearance needed. That zero forward clearance is a practical advantage in tight enclosures where you're stacking breakers close to the door.","metaTitle":"Siemens 3RV2311-1AC20 SIRIUS Circuit Breaker, 100 kA","metaDescription":"Siemens 3RV2311-1AC20 SIRIUS circuit breaker for starter combinations. 100 kA breaking capacity at 400 V. 45 mm wide, DIN-rail mount.
