Product details

What the 100 kA rating means for the panel

The Siemens 3RV2811-1GD10 is a SIRIUS circuit breaker sized S00, designed specifically for transformer protection per UL 489 and CSA C22.2 No.5.

Any mounting position is permitted. Clearance requirements: 70 mm upward and downward, 30 mm to the side, zero forward or backward. Main circuit terminals accept 1 to 10 mm² solid or stranded, up to 2×10 mm²; screwdriver shaft diameter 5 to 6 mm, Pozidriv size 2 tip.

Transformer-duty design

Unlike a standard motor-protective circuit breaker, this unit is engineered for transformer inrush and overload characteristics per UL 489. The gG fuse coordination values at 400 V are 50 A, at 500 V 40 A, and at 690 V 35 A — these define the maximum backup fuse for the breaker's short-circuit rating. No ground-fault or phase-failure detection built in; external protection is needed for those functions.

Frequently asked questions

Where can I buy 3RV2811-1GD10?

Sourced to order against an RFQ through independent distribution. Request a quote for current pricing and availability.

What is the breaking capacity of 3RV2811-1GD10 at 400 V?

100 kA at 400 V AC. At 690 V AC it is 4 kA.

What compliance documentation does Siemens provide for 3RV2811-1GD10?

The breaker carries UL 489 and CSA C22.2 No.5 certification for transformer protection. RoHS and REACH declarations are standard Siemens documentation for this series.
