Product details

The instantaneous magnetic short-circuit trip is set at 819 A, which is roughly 13x the rated current — a typical threshold for motor start-up inrush without nuisance tripping. Rated voltage is 690 V. Typical power loss is 20 W. The S3 frame dimensions — 174 mm deep, 70 mm wide, 165 mm high — mean it occupies the same footprint as other S3 breakers in the SIRIUS family. Clearance requirements: 50 mm upwards, 167 mm forwards, 30 mm at the sides.

Wiring and integration

Main circuit terminals are screw-type with box terminals, top and bottom arrangement. Wire capacity is generous: 2x 2.5–16 mm² solid/stranded, or 2x 10–50 mm², or single 10–70 mm². For finely stranded with ferrules, 2x 2.5–35 mm² or single 2.5–50 mm². AWG equivalents: 2x 10–1/0, single 10–2/0. Torque spec: 4–6 N·m. That's enough lug for parallel feeders or larger motor leads. Operating frequency is 50–60 Hz, so it's fine for both 50 Hz European and 60 Hz North American installations. Maximum switching frequency at AC-3 is 15 operations per hour — this is a motor protection breaker, not a contactor for high-cycle applications. Ambient range during operation: -20 to +60 °C; transport/storage: -50 to +80 °C.

Lifecycle status is current production. The 3RV5341-4JC10 is an active catalog item — no phase-out notice on record. Compliance documentation includes RoHS substance prohibition date of July 1, 2006, and the product carries the SIRIUS brand. The insulation voltage is rated 690 V at pollution degree 3, and surge voltage resistance is 6 kV. Shock resistance per IEC 60068-2-27: 25 g for 11 ms.

Frequently asked questions

Will 3RV5341-4JC10 fit a panel designed for 3RV6021-4DA10?

Both are S3 frame breakers on 35 mm DIN rail, so the footprint and mounting are the same. The 3RV5341-4JC10 has a 63 A AC-3 rating versus the 3RV6021-4DA10's lower rating — check your load current. Terminal layout and clearance requirements are identical per the S3 frame standard.
