Product details

Breaking capacity: 100 kA at 240 VAC, 50 kA at 400 VAC, 12 kA at 500 VAC, 5 kA at 690 VAC. Three-pole, screw-type box terminals for the main circuit accepting 2x 0.75…16 mm² solid or 2x 0.75…25 mm² stranded, with a single conductor up to 35 mm². Finger-safe touch protection — no live metal exposed at the front, so panel builders can work near it without additional shrouding. Zero clearance needed at the sides or rear, so it packs tight in a crowded enclosure. IP20 on the front — fine for a dry indoor panel; not rated for washdown.

Lifecycle and sourcing — still in active production

Lifecycle stage is current — Siemens still manufactures this order code. Substance prohibitance date of 07/01/2006 indicates RoHS compliance for that cutoff.

Integration into a panel — DIN rail fit and wiring

Any mounting position accepted, so it can go sideways or upside-down in a tight sub-panel. Depth 149 mm, width 55 mm, height 140 mm. Auxiliary switch optional — the breaker accepts a snap-on auxiliary contact block if you need remote status feedback. No ground-fault detection built in; phase-failure detection is included.

Environmental and mechanical limits

Shock rated at 25 g for 11 ms — survives typical panel vibration and occasional drops during installation. Power dissipation 14.5 W in hot operating state, or 4.8 W per pole. That heat needs to be considered in a sealed enclosure with multiple breakers ganged together. Surge voltage resistance rated at 6 000 V — coordinates with standard industrial SPDs for impulse withstand.

Frequently asked questions

What is the 3RV1431-4AA10's depth?

Depth is 149 mm. That's the critical dimension for shallow enclosure clearance.

What solid wire size does the 3RV1431-4AA10 accept?

The main circuit terminals accept 2x 0.75…16 mm² solid. Stranded goes up to 2x 25 mm² or 1x 35 mm².

Will the 3RV1431-4AA10 drop into a panel specified around the 3RV6021-4DA10?

Both mount on 35 mm DIN rail per DIN EN 50022 and share the same three-pole form factor. The 3RV1431-4AA10 is a transformer-protection breaker; the 3RV6021-4DA10 is a motor-protection variant. Check the trip curve and continuous rating against your load before substituting — the mechanical footprint is compatible, but the protective function differs.

What compliance documentation does Siemens provide for the 3RV1431-4AA10?

The part carries a substance prohibitance date of 07/01/2006, indicating RoHS compliance per the original EU directive. Finger-safe touch protection and IP20 front protection are design features, not third-party certifications. For full UL, CSA, or IEC declarations, request the manufacturer's declaration of conformity with your RFQ.
