Design Of The Productfor transformer protection

Product details

The 55 mm width and 140 mm height leave a compact footprint on the rail; 149 mm depth means it projects into the enclosure that far, so check gland-plate clearance in shallow boxes. Zero clearance required at the back and sides — no derating for side-by-side stacking on the rail. IP20 on the front keeps fingers out but expects enclosure-level sealing for washdown environments.

Wiring and terminations

Main circuit terminals are screw-type box terminals accepting 2x (0.75…16 mm²) solid or 2x (0.75…25 mm²) stranded, with a single conductor up to 35 mm² stranded. AWG equivalents run 2x (18…2) for the main contacts. Auxiliary and control circuits use separate screw terminals. The wire range covers most panel-building gauges without needing adapters.

Shock rated at 25g for 11 ms, so it survives shipping drops and moderate machine vibration. Surge voltage resistance is 6 000 V.

Frequently asked questions

How do I get current pricing and availability for 3RV1431-4DA10?

Submit an RFQ through this listing. The part is sourced to order through independent distribution; pricing and stock levels are confirmed at quote time.

When sourcing 3RV1431-4DA10, what's the closest functional second-source — 3RV6021-4DA10?

The 3RV6021-4DA10 is a peer in the same SIRIUS family but belongs to a different series generation. Both are 3-pole circuit breakers with screw terminals and snap-on DIN rail mounting, but the 3RV1431-4DA10 is specifically designed for transformer protection (Class 10 trip, 25 A continuous, 11 kW at 400 V). The 3RV6021-4DA10 may share the same footprint and terminal layout, but verify the trip characteristic and breaking capacity against your application before substituting — the 3RV1431-4DA10's 50 kA at 400 V and phase failure detection are not guaranteed on the peer without checking its own

What is 3RV1431-4DA10's listed depth (149 mm) on this component line?

The depth is 149 mm, measured from the mounting rail face to the furthest projection. This is the dimension to check against enclosure depth when planning gland-plate clearance.

What is 3RV1431-4DA10's listed solid (2x (0.75... 16 mm²)) on this component line?

The solid conductor range for the main circuit terminals is 2x (0.75…16 mm²). This means two solid conductors per terminal, each between 0.75 and 16 mm² cross-section.

Will 3RV1431-4DA10 drop into a panel that was specified around 3RV6021-4DA10 without rewiring?

Both parts share the same 35 mm DIN rail mounting per DIN EN 50022 and use screw-type box terminals, so the mechanical fit and terminal type are identical. The wire range (solid 2x 0.75…16 mm², stranded 2x 0.75…25 mm²) is also the same. However, the 3RV1431-4DA10 is a transformer-protection breaker with Class 10 trip, while the 3RV6021-4DA10 may have different trip characteristics. Confirm the trip class and breaking capacity match your load before swapping — no rewiring needed if the ratings align.
