Product details

It's rated 25 A operational current at AC-3 duty at 400 V, which is the standard motor-switching load: that 25 A figure is what governs motor sizing, not a resistive-heater rating. The magnetic short-circuit trip responds at 325 A, so it clears a bolted fault fast without waiting for a thermal bimetal.

Size S2 frame: 55 mm wide, 140 mm tall, 149 mm deep. Mounting position any, so you can lay it sideways in a tight gland-plate layout. Clearance needs: 50 mm above and below, 30 mm to the side, 140 mm forward. That 149 mm depth is the body plus terminals; factor it into your enclosure depth before you cut the backplate.

Main current circuit uses screw-type terminals with box terminals — accepts 2x (0.75 to 25 mm²) solid or stranded, or 1x up to 35 mm². For AWG: 2x (18 to 2), 1x (18 to 2). Torque spec: 3 to 4.5 N·m on the main contact screws. Connections arranged top and bottom, which is the standard feed-through layout for a motor branch circuit.

Environmental and ratings

Relative humidity 10 to 95 % during operation. Shock resistance 25 g / 11 ms per IEC 60068-2-27. Installation altitude up to 2 000 m above sea level. Insulation voltage 690 V at pollution degree 3. Surge voltage resistance 6 kV.

Frequently asked questions

Where can I buy 3RV5331-4DC10 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 number.

What is 3RV5331-4DC10's listed depth?

The listed depth is 149 mm, which is the body plus screw terminals. Factor that into your enclosure depth before cutting the backplate.

What compliance documentation does this brand provide for 3RV5331-4DC10?

The part carries a substance prohibitance date of 07/01/2006, indicating RoHS compliance. The SIRIUS series typically supports IEC and UL certifications; verify the specific documentation package with your order.

Will 3RV5331-4DC10 drop into a panel specified around 3RV6021-4DA10?

Both are SIRIUS size S2 circuit breakers on 35 mm DIN rail, so the footprint and mounting are the same. The key difference is the trip rating and magnetic setting — verify the 3RV6021-4DA10's AC-3 current and instantaneous trip against your motor FLA before swapping.
