Product details

Motor protection circuit breaker, Size S00 — 100 kA SCCR, Trip Class 10

No ground fault detection on this variant; if you need that, you are looking at a different module in the SIRIUS family.

Mounting and wiring — DIN rail, spring terminals, any position

No screw torque to check; just strip to 8 mm and push in. The screwdriver shaft diameter is 3 mm for the auxiliary contact terminals. Dimensions: 45 mm wide, 106 mm high, 97 mm deep. Clearance requirements: 50 mm upwards, 50 mm downwards, 30 mm to the side, zero forwards or backwards. That zero forwards/backwards clearance means it can sit flush against the panel door or back wall — handy in shallow enclosures.

Frequently asked questions

What is the breaking capacity of 3RV2011-1AA20-0BA0?

100 kA at 400 V AC, and the same 100 kA at 240 V, 500 V, and 690 V AC. That is a high interrupting rating for a Size S00 frame — it simplifies panel SCCR coordination.

Will 3RV2011-1AA20-0BA0 drop into a panel specified for 3RV2011-0BA20?

Both are Size S00 with the same 45 mm width and DIN rail mount, so the mechanical fit is the same. The key difference is the terminal type: this unit has spring-loaded terminals, while the -0BA20 variant uses screw terminals. If the panel wiring was designed for screw-clamp ferrules, the spring terminals will still accept them — but verify the wire strip length matches the spring terminal spec (8 mm typical).
