It provides Class 10 overload protection with an A-release (thermal overload) set for 1.8-2.5 A and a magnetic short-circuit release (N-release) at 33 A. This is the standard switching capacity variant, suitable for most motor branch circuits in a panel. ## Panel integration and packaging Packaged as 35 units per reusable carton, each piece individually boxed. The S0 frame snaps onto a standard 35 mm DIN rail; dimensions are 133 x 52.5 x 106.5 mm. That's a compact footprint — leaves room alongside a contactor for a compact motor starter combination. The spring terminals are tool-less for the wire but need a small screwdriver to open the cage; standard for SIRIUS 3RV2.","metaTitle":"Siemens 3RV2021-1CA20-Z X95 SIRIUS Motor Protector, 1.8-2.5","metaDescription":"Siemens SIRIUS 3RV2 motor starter protector, size S0, Class 10, A-release 1.8-2.5 A, N-release 33 A, spring terminals.
