Product details

Transformer-protection circuit breaker, size S00

The Siemens SIRIUS 3RV2811-1ED10 is a circuit breaker in the S00 frame, designed specifically for transformer protection and listed to UL 489 / CSA C22.2 No.5. Breaking capacity reaches 100 kA at 240 V AC and 400 V AC, 100 kA at 500 V AC, and 4 kA at 690 V AC — the 690 V figure drops further to 6 kA for AC operation. This SCCR headroom suits transformer primary-side protection where fault currents can exceed 50 kA on a stiff utility feed. Backup fuse coordination is specified: gG 32 A at 400 V and 500 V, gG 25 A at 690 V. The rated operational voltage spans 20 to 690 V, covering most low-voltage transformer primaries up to 480/600 V class.

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

Frequently asked questions

Will 3RV2811-1ED10 drop into a panel that was specified around 3RV2311-1CC10 without rewiring?

Both are S00-frame breakers on 35 mm DIN rail, so the footprint and mounting are identical. The 3RV2811-1ED10 is designed specifically for transformer protection per UL 489, while the 3RV2311-1CC10 targets motor protection (overload + short-circuit). Verify the protection function and trip curve match your application before swapping — the mechanical fit is the same, but the release characteristics differ.

What compliance documentation does this brand provide for 3RV2811-1ED10?

The breaker carries UL 489 and CSA C22.2 No.5 listing for transformer protection. Siemens standard documentation includes the declaration of conformity (CE), RoHS and REACH compliance statements, and the product datasheet. Specific certificates are available on request at quote time.
