Product details

Motor Protection Circuit Breaker – 32 A, Trip Class 20, 50 kA SCCR

The Siemens 3RV1031-4EB15-ZW97 is a SIRIUS motor protection circuit breaker rated for 32 A continuous current and 15 kW at 400 V AC-3 duty. Trip Class 20 means it allows a 20-second overload before tripping — standard for general-purpose motor starting where the inrush transient needs room.

Mounting and Wiring – DIN Rail, Screw Terminals, Any Position

The screw-type terminals on the main circuit accept solid 2x (0.5…1.5 mm²) and 2x (0.75…2.5 mm²), plus stranded up to 35 mm² on a single conductor. That covers everything from control-circuit tails to motor feeder cables. Mounting position is any, which helps when the panel layout is tight. Zero clearance needed at the back or sides — no derating for side-by-side packing.

Front IP20 — protected against finger contact, fine for enclosed panel use. RoHS compliance date marked as 07/01/2006, meaning it meets the EU directive since then.

Frequently asked questions

What is 3RV1031-4EB15-ZW97's listed depth?

Depth is 149 mm. That's the dimension from the DIN-rail mounting surface to the front of the housing — important for enclosure depth clearance.

What is the solid wire range for the main terminals?

Solid wire: 2x (0.5…1.5 mm²) and 2x (0.75…2.5 mm²) per terminal. Stranded accepts up to 35 mm² on a single conductor.
