Product details

The IP20 front means it's panel-internal; no washdown rating here.

Breaking capacity drops as voltage climbs: 100 kA at 240 V AC, 50 kA at 400 V AC, 8 kA at 500 V AC, and 5 kA at 690 V AC. At 400 V — the common industrial panel voltage — 50 kA gives solid headroom for most downstream coordination studies. The 690 V figure (5 kA) is lower; if your panel feeds a 690 V motor branch, verify the fault current doesn't exceed that.

Trip class and protection features

That's typical for a motor-protective breaker in this class — you'd add a separate ground-fault module if the application requires it.

Main circuit terminals accept solid conductors 2× (2.5…16 mm²) or stranded 2× (10…50 mm²) and 1× (10…70 mm²). Fine-stranded with ferrule: 2× (2.5…35 mm²) and 2.5…50 mm². Auxiliary and control circuit terminals are screw-type as well. The box-terminal design on the main circuit gives a reliable connection for the higher current range.

Shock rated at 25 g / 11 ms. Mounting position any — no derating needed for horizontal or vertical orientation. Zero clearance at the sides and back (0 mm) simplifies panel layout.

Frequently asked questions

Where can I buy 3RV1041-4LA10-ZW95 and how do I get a price?

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 for a firm price and lead time.

What is 3RV1041-4LA10-ZW95's listed depth (174 mm) on this component line?

The depth is 174 mm. That's the dimension from the DIN rail mounting surface to the front of the housing — plan for that clearance in your panel layout.

What is 3RV1041-4LA10-ZW95's listed solid (2x (2.5... 16 mm²)) on this component line?

The main circuit terminals accept solid conductors 2× (2.5…16 mm²). That's the wire range for solid (not stranded) copper — use that for permanent wiring where flexibility isn't needed.

Will 3RV1041-4LA10-ZW95 drop into a panel that was specified around 3RV6021-4DA10 without rewiring?

Not without checking. Both are SIRIUS 3RV series breakers with the same DIN rail footprint and screw terminals, but the 3RV1041-4LA10-ZW95 is a 90 A Class 10 device; the 3RV6021-4DA10 has different ratings. The terminal wire ranges may also differ — compare the solid and stranded capacities against your existing wiring before swapping.

What compliance documentation does this brand provide for 3RV1041-4LA10-ZW95 (RoHS, REACH, UL, IEC)?

The part carries a substance prohibition date of 07/01/2006, indicating RoHS compliance from that date. As a Siemens SIRIUS product, it is designed to meet IEC/EN 60947 standards. For specific UL, CSA, or REACH documentation, request the manufacturer's declaration from your distributor.
