The thermal overload release handles sustained overcurrents, while the magnetic short-circuit trip clears faults fast enough to keep downstream contactors and cables within their withstand ratings. The 45 mm width and 96 mm depth fit standard S0-size panel cutouts. Any mounting position works, which helps when the gland plate is already full. Main contacts accept 2x (0.5…1.5 mm²) solid/stranded or 2x (0.75…2.5 mm²), AWG 2x (16…12) or 2x (14…8). Auxiliary contacts take 2x (0.5…1.5 mm²) or 2x (0.75…2.5 mm²), AWG 2x (20…16) or 2x (18…14). Terminal torque for main contacts: 2…2.5 N·m. Operating temperature range -20…+60 °C, transport/storage -50…+80 °C. Relative humidity 10…95 % during operation. Shock rated at 25 g / 11 ms per IEC 60068-2-27. Surge voltage resistance 6 kV. RoHS compliance date (substance prohibition) 05/01/2012. Typical power loss 8 W.","metaTitle":"Siemens 3RV6021-4CA15 SIRIUS Motor Protection Circuit Breake","metaDescription":"Siemens 3RV6021-4CA15 SIRIUS motor protection circuit breaker, 22 A rated, CLASS 10 trip, 690 V, 3-pole.

The deciding difference is the rated current — the 4DA10 carries a higher amp rating. Verify your motor FLA before substituting; the mounting footprint and terminal layout are identical, so it drops into the same DIN-rail position without rewiring."},{"question":"Will 3RV6021-4CA15 fit a panel designed for 3RV6021-4DA10?","answer":"Yes. Both are size S0 with the same 45 mm width and 96 mm depth, same DIN-rail snap-on mounting, same clearance requirements. No rewiring needed — the terminal layout and conductor sizes are identical."},{"question":"Where can I buy 3RV6021-4CA15?","answer":"Sourced and quoted to order against an RFQ through independent distribution.
