Product details

The Siemens 3RV2811-0KD10 is a SIRIUS circuit breaker in the S00 frame size, designed specifically for transformer protection and listed to UL 489 / CSA C22.2 No.5. The breaking capacity is 100 kA at 400 V AC, and it holds that same 100 kA rating at 240 V, 500 V, and 690 V AC, so it handles high-fault utility feeds without cascading upstream. Rated voltage spans 20 to 690 V, with the AC-3 maximum switching voltage at 690 V — covers most motor and transformer circuits in industrial panels.

Main circuit terminals are M4 screw-type, accepting 1 to 10 mm² solid or stranded, up to 2 × 10 mm². Use a Pozidriv size 2 tip with a 5–6 mm shaft diameter.

Frequently asked questions

What compliance documentation does 3RV2811-0KD10 carry?

It is designed to UL 489 and CSA C22.2 No.5 for transformer protection. The SIRIUS brand typically provides RoHS and REACH declarations; confirm with the manufacturer for the specific certificate.
