Trip Class 10 opens within 10 seconds.
Width is 45 mm, depth 97 mm, height 106 mm — a compact two-module-wide footprint that leaves room for contactors and overloads on the same rail. No screw torque to check, no re-tightening on thermal cycles — just strip to the right length and push in. Clearance distances: 50 mm upwards and downwards, 30 mm at the sides, 0 mm forwards and backwards. That 0 mm backwards means it can sit flush against the back panel or another device.
Both are SIRIUS 3RV2 motor-protective breakers with the same 45 mm width, DIN-rail snap-on mounting, and spring-loaded terminals — so the footprint and wiring method are identical. The difference is in the internal trip characteristics and accessory compatibility; verify the thermal setting range and any special-function modules (like undervoltage releases) before swapping.
Alternative models and sibling configurations in the same Siemens series. For obsolete or discontinued parts, these models can serve as compatible replacements or functional alternatives for plant maintenance.
