Design Of The ProductFor transformer protection according to UL 489/CSA C22.2 No.5

Product details

The Siemens 3RV2811-0AD10 is a SIRIUS circuit breaker specifically designed for transformer protection, complying with UL 489 and CSA C22.2 No.5. Rated for 20 to 690 V, this breaker delivers a consistent 100 kA breaking capacity across the 240 V to 690 V AC range. Power dissipation at 5.5 W in hot operating state is modest — no special ventilation needed in a standard enclosure.

Panel fit and clearances

That zero forward/backward clearance means you can butt it against a back panel or enclosure door without derating — handy for tight enclosures. Terminals accept 1 to 10 mm² solid or stranded wire, up to 2x 10 mm² — screw-type terminals with M4 screws for the main contacts. Use a Pozidriv size 2 tip or a 5-6 mm diameter screwdriver shaft.

Mechanical endurance and switching frequency

Main contacts are rated for 100,000 typical mechanical operations. Maximum switching frequency at AC-3 and AC-3e duty is 15 operations per hour.

Frequently asked questions

Will 3RV2811-0AD10 drop into a panel specified around 3RV2011-0AA10 without rewiring?

Both are Size S00 breakers on 35 mm DIN rail with similar dimensions, so the mechanical fit is the same. The 3RV2811-0AD10 is designed for transformer protection per UL 489/CSA C22.2 No.5, while the 3RV2011 series covers motor and general applications — check your application's coordination study before swapping.
