Product details

Motor protection circuit breaker for high-fault panels

The 3RV2041-4KA10: Trip Class 10. Phase failure detection onboard. Mounts via snap-on or screw fixing to 35 mm DIN rail, screw-type terminals for main circuit.

Panel layout clearances

Width of 70 mm, height of 165 mm, depth of 176 mm. Minimum free space above and below the device is 150 mm each, and 30 mm to the side. These clearances ensure proper heat dissipation and access for screw-terminal torqueing. Terminal cross-sections: solid/stranded main wires 2x (2.5…16 mm²) or 1x (10…70 mm²) (size? Actually: Solid 2x (2.5...16 mm²), and: for larger sizes). The 176 mm depth is a typical DIN-rail device footprint; plan for clearance behind the panel door for wiring.

Frequently asked questions

What are the key dimensions and mounting requirements for this breaker?

Width 70 mm, height 165 mm, depth 176 mm. Minimum clearances: 150 mm above and below, 30 mm at the side. Mounts on 35 mm DIN rail per DIN EN 60715. Screw terminals accept 2x (2.5…16 mm²) solid/stranded conductors.
