Product details

The Siemens SIRIUS 3RV2811-1CD10 is a size S00 circuit breaker designed specifically for transformer protection, complying with UL 489 and CSA C22.2 No.5.

SCCR and selectivity

Rated short-circuit breaking capacity reaches 100 kA at 240 V, 400 V, and 500 V AC, dropping to 10 kA at 690 V AC. The gG fuse coordination values are 25 A at 400 V and 500 V, and 20 A at 690 V.

Integration notes

Clearance requirements: 70 mm upward and downward, 30 mm to the side, zero forward or backward. The screwdriver shaft must be 5 to 6 mm diameter with a Pozidriv size 2 tip. Main contact terminal screws are M4.

Frequently asked questions

What is the SCCR of 3RV2811-1CD10 at 400 V?

100 kA at 400 V AC, which means it safely interrupts faults up to 100,000 A at that voltage without cascading upstream.

Where can I buy 3RV2811-1CD10?

This part is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time.

What are the mounting clearances for 3RV2811-1CD10?

70 mm upward and downward, 30 mm to the side, zero forward or backward. The breaker mounts on a 35 mm DIN rail per DIN EN 60715.
