The thermal overload release handles the running protection; the magnetic short-circuit trip clears faults fast. S0 frame footprint: 45 mm wide, 97 mm tall, 96 mm deep. That's a standard three-pole MCCB width — fits most DIN-rail enclosures without surprises. Main-circuit terminals accept 2x (0.5…1.5 mm²) solid/stranded or 2x (0.75…2.5 mm²) — AWG equivalents 2x (16…12) and 2x (14…8). Auxiliary terminals are 2x (0.5…1.5 mm²) or 2x (0.75…2.5 mm²) — AWG 2x (20…16) and 2x (18…14). Wire it with ferruled stranded or solid — no special crimp tool needed. The transverse auxiliary switch design means the contact block sits alongside the breaker, not stacked on top, keeping the overall height low.","metaTitle":"Siemens 3RV6021-4PA15 SIRIUS Motor Protection CB, 36 A, Clas","metaDescription":"Siemens 3RV6021-4PA15 SIRIUS motor protection circuit breaker, 36 A rated current, Class 10 trip, 690 V, S0 frame, DIN rail mount.

Submit an RFQ with your quantity and target delivery; the response will include current pricing and lead time from the channel that can fulfill it."},{"question":"What is the closest functional second-source to 3RV6021-4PA15?","answer":"The 3RV6021-4DA10 is a functional peer in the same S0 frame, but it carries a different current rating — check your motor FLA before substituting. Both are SIRIUS Class 10 breakers with the same mounting footprint and terminal specs, so the swap is mechanical but the trip point changes."},{"question":"What is 3RV6021-4PA15's depth on this component line?","answer":"96 mm. That's the body depth behind the panel face — account for wiring clearance on top of that."},{"question":"Will 3RV6021-4PA15 drop into a panel specified around 3RV6021-4DA10 without rewiring?","answer":"Yes, mechanically and electrically — same S0 frame, same DIN rail mount, same screw terminal layout. The difference is the current rating; verify the motor FLA matches the 36 A rating, not the 4DA10's rating."},{"question":"What compliance documentation does this brand provide for 3RV6021-4PA15?","answer":"RoHS compliant per the substance prohibition date of May 1, 2012.
