Product details

It protects three-phase motor circuits up to 690 V AC-3, switching at up to 15 operations per hour. 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.

Frequently asked questions

What is the closest functional alternative to 3RV6021-4CA15?

The 3RV6021-4DA10 is a sibling in the same S0 frame and SIRIUS family. 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.

Will 3RV6021-4CA15 fit a panel designed for 3RV6021-4DA10?

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.

Where can I buy 3RV6021-4CA15?

Sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — submit an RFQ for a firm price and lead time.

What compliance documentation does Siemens provide for 3RV6021-4CA15?

RoHS compliance is confirmed with a substance prohibition date of 05/01/2012. The part carries IEC 60068-2-27 shock ratings and surge voltage resistance per IEC standards. Full declarations and certificates are available from Siemens upon request.
