Product details

It combines a thermal overload release (CLASS 10 trip curve) with a magnetic short-circuit trip in a single 3-pole device rated 40 A at 690 V.

The S0 frame size (45 mm wide, 97 mm tall, 96 mm deep) fits standard motor control center buckets and small panel enclosures. Screw-type terminals on both main and auxiliary circuits accept 2×(0.5…1.5 mm²) or 2×(0.75…2.5 mm²) solid/stranded, or AWG equivalents. Main contact torque spec: 2…2.5 N·m.

Electrical and environmental ratings

Rated operational current 40 A at AC-3 duty (motor switching), with a maximum operating frequency of 15 operations per hour at that load. Rated insulation voltage 690 V, surge voltage resistance 6 kV. Power dissipation 14 W typical. Relative humidity 10…95 %. Shock rated at 25 g / 11 ms per IEC 60068-2-27.

Frequently asked questions

Where can I buy 3RV6021-4FA15 and how is it quoted?

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

Will 3RV6021-4FA15 drop into a panel built for 3RV6021-4DA10 without rewiring?

Both are S0-frame SIRIUS motor protection breakers with the same 45 mm width and screw-terminal layout, so the mechanical fit and terminal positions are identical. The key difference is the 40 A rating on this part versus the 4DA10's lower rating — verify the motor FLA matches before swapping.

What are the key dimensions of 3RV6021-4FA15?

Width 45 mm, height 97 mm, depth 96 mm. Clearance: 70 mm above and below, 30 mm to the sides, zero forward or backward.

What compliance documentation is available for 3RV6021-4FA15?

The part carries a substance prohibitance date of 05/01/2012, indicating RoHS/REACH compliance. Standard Siemens documentation includes CE, UL, CSA, and IEC certifications per the SIRIUS series.
