Design Of The Productfor motor protection

Product details

The 36 A rating at AC-3 (motor switching) covers motors up to roughly 15 kW at 400 V, depending on full-load amps. 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.

Frequently asked questions

Where can I buy 3RV6021-4PA15 and how do I get a price?

Sourced to order against an RFQ through independent distribution. 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.

What is the closest functional second-source to 3RV6021-4PA15?

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.

What is 3RV6021-4PA15's depth on this component line?

96 mm. That's the body depth behind the panel face — account for wiring clearance on top of that.

Will 3RV6021-4PA15 drop into a panel specified around 3RV6021-4DA10 without rewiring?

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.

What compliance documentation does this brand provide for 3RV6021-4PA15?

RoHS compliant per the substance prohibition date of May 1, 2012. The product carries IEC 60947-2 coordination ratings (6 kV surge voltage resistance,) and shock testing per IEC 60068-2-27. Standard Siemens SIRIUS documentation — CE, UKCA, and EAC declarations are available on request.
