Product details

Rated insulation voltage spans 20 to 690 V. Breaking capacity is voltage-dependent: 100 kA at 240 V, 30 kA at 400 V, 6 kA at 500 V, and 2 kA at 690 V. Phase failure detection is included; ground fault detection is not. The main circuit connects via screw-type terminals accepting up to 2× 25 mm² or 1× 35 mm² solid or stranded copper, with M6 contact screws.

The breaker occupies 75 mm width, 140 mm height, and 149 mm depth. Mounting position is any orientation. Required clearances: 50 mm upwards, 50 mm downwards, 10 mm to the side, 0 mm forwards and backwards — so it can be stacked tightly against the back panel or adjacent devices without extra air gap.

Environmental and Operating Limits

Maximum switching rate under AC-3 duty is 15 operations per hour.

The 3RV2131-4SA10 carries a current lifecycle stage.

Frequently asked questions

What is 3RV2131-4SA10's listed note (1) on this component line?

The evidence lists a Note value of 1, which typically indicates a general remark or condition in the manufacturer's documentation.

Will 3RV2131-4SA10 drop into a panel that was specified around 3RV1011-1HA10 without rewiring?

The 3RV2131-4SA10 mounts on the same 35 mm DIN rail standard and uses screw terminals, but the 3RV1011-1HA10 is a different frame size and rating — verify the terminal layout and clearance dimensions before direct swap.
