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.","metaTitle":"Siemens 3RV1431-4AA10 SIRIUS Circuit Breaker, 16 A, Class 10","metaDescription":"Siemens 3RV1431-4AA10 SIRIUS circuit breaker for transformer protection. 16 A continuous, Class 10 trip, 50 kA at 400 VAC.

The 3RV1431-4AA10 is a transformer-protection breaker; the 3RV6021-4DA10 is a motor-protection variant.
