Zero clearance needed at the back or sides — you can pack these tight in a panel. Mounting position is any orientation. Spring terminals on the main circuit accept 2x (0.25... 2.5 mm²) solid or 2x (0.25... 1.5 mm²) finely stranded with ferrules. AWG equivalent is 2x (24... 14). No screwdriver torque to worry about — strip, insert, done. The IP20 finger-safe front means you can work in a live panel without exposed metal. The 100 kA rating holds at both 240 V and 400 V AC. That's typical for this frame size — the arc energy scales with voltage. For a 400 V panel with high fault current (say a transformer-fed MCC), this breaker handles it. For 690 V industrial systems, you'll need to check the available fault current against the 2 kA limit. Surge voltage withstand is 6 000 V. The 7.25 W power loss in hot operating state matters for thermal management.","metaTitle":"Siemens 3RV1011-1FA20-ZX95 SIRIUS Motor Protection Circuit B","metaDescription":"Siemens 3RV1011-1FA20-ZX95 SIRIUS motor protection circuit breaker, 5 A continuous, CLASS 10 trip, 100 kA at 400 V AC.
