| Design Of The Product | for starter combinations |
The instantaneous short-circuit trip responds at 975 A, clearing faults fast enough to protect downstream contactors and cables.
The S3 frame size (174 mm deep, 70 mm wide, 165 mm tall) fits standard panel layouts. Clearance: 50 mm above and below, 30 mm to the side for airflow and wiring access. Screw-type box terminals on top and bottom accept up to 70 mm² solid/stranded or 50 mm² fine-stranded with ferrules — torque to 4–6 N·m. Any mounting position works.
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 to get a firm price and lead time.
The depth is 174 mm, with a width of 70 mm and height of 165 mm. Clearance above and below is 50 mm, 30 mm to the side.
Both are SIRIUS circuit breakers on the same DIN-rail footprint (35 mm rail per DIN EN 50022), but the 3RV6021-4DA10 is a different frame size and rating. The 3RV5341-4KC10 is size S3 with 75 A AC-3; the 3RV6021-4DA10 is a different variant. Physical interchange depends on panel layout and terminal clearance — verify the mounting dimensions and wiring space before swapping.
The part carries a RoHS substance prohibitance date of July 1, 2006. It is designed to IEC standards (IEC 60068-2-27 for shock resistance, 25g/11 ms). For UL/CSA and REACH declarations, refer to the manufacturer's documentation package available on request.
