Product details

It carries a rated continuous current of 8 A and switches a 3 kW motor at 400 V AC. Mounting position is any, which helps when panel layout is tight.

The interrupting ratings are 100 kA at 240 V AC, 100 kA at 400 V AC, 42 kA at 500 V AC, and 6 kA at 690 V AC.

Screw-type terminals on both the main and auxiliary/control circuits. Each pole accepts 2× (1 … 2.5 mm²) solid or stranded, or 2× (2.5 … 6 mm²) — the larger cross-section is useful for looping through the line feed without a separate terminal block. Finely stranded wire with core end processing (ferrules) is also supported in the same ranges. AWG equivalents are 2× (14 … 10).

Shock resistance is 25 g for 11 ms. RoHS compliance date is 01.05.2012, meaning the part meets the EU RoHS substance restrictions from that date forward.

Frequently asked questions

Where can I buy 3RV1021-1HA10-ZW96 and how do I get a price?

This part is 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 is the closest functional second-source — 3RV1011-1HA10?

The 3RV1011-1HA10 is a physically smaller frame (S00 vs S0) with a lower maximum breaking capacity and different terminal layout. It will not drop into a panel wired for the 3RV1021-1HA10-ZW96 without re-drilling the mounting holes and re-terminating the conductors. The 3RV1021-1HA10-ZW96 is the correct replacement for any BOM that calls out the S0 frame size.

What is 3RV1021-1HA10-ZW96's listed depth?

The depth is 96 mm. Overall dimensions are 45 mm wide, 97 mm high, and 96 mm deep. The backwards projection from the DIN rail is 0 mm — the body sits flush against the rail.

What compliance documentation does this brand provide for 3RV1021-1HA10-ZW96?

The part is RoHS compliant per the substance prohibition date of 01.05.2012. It is designed to IEC 60947-2 and carries the SIRIUS brand documentation package including a CE declaration of conformity. UL and CSA listings are standard for the SIRIUS 3RV1 family, though specific file numbers are not listed in this entry.
