Product details

Motor Protection Circuit Breaker, 16 A, Class 10

It protects three-phase motors up to that current level against overload and short-circuit, with a magnetic short-circuit trip and a thermal overload release built into a single 3-pole device. The 690 V AC-3 rating covers most European 400 V motor circuits with headroom for 690 V applications.

The 45 mm width (3 modules) fits standard enclosure cutouts for Size S0 breakers. Screw-type terminals on both main and auxiliary circuits accept 2x (0.5...1.5 mm²) solid/stranded or 2x (0.75...2.5 mm²) with ferrules; AWG equivalents 2x (16...12) and 2x (14...8) for mains, 2x (20...16) and 2x (18...14) for auxiliaries. Terminal torque: 2...2.5 N·m.

Relative humidity 10 to 95 % during operation. Shock resistance 25 g / 11 ms per IEC 60068-2-27. Substance prohibition date 05/01/2012 — RoHS and REACH compliance documentation is standard for this brand and order code.

Frequently asked questions

What is the rated current and trip class of 3RV6021-4AA15?

Rated operational current is 16 A with Trip Class 10 thermal overload release, suitable for standard motor protection.

Will 3RV6021-4AA15 drop into a panel specified for 3RV6021-4DA10?

Both are Size S0 frame breakers with the same 45 mm width and DIN rail mounting, so the mechanical fit is identical. The difference is in the rating — verify the 4DA10's current setting against your motor FLA before swapping.

Where can I buy 3RV6021-4AA15?

This part is sourced and quoted to order against an RFQ through independent distribution channels. Availability and current pricing are confirmed at quote time.

What compliance documentation does Siemens provide for 3RV6021-4AA15?

Standard RoHS and REACH compliance documentation is available, with a substance prohibition date of 05/01/2012. The device is designed to IEC/EN 60947 standards.
