Product details

Ground fault detection is not included — that requires an external module or a separate ground-fault relay.

Mounting position is any, so vertical or horizontal panel layouts are fine. Screw-type terminals on both main and auxiliary/control circuits accept solid or stranded conductors: 2× (1 … 2.5 mm²) and 2× (2.5 … 6 mm²) per clamp, or AWG 14–10. No backward or side clearance required (0 mm), so you can pack devices tightly on the rail.

Substance prohibitance date of 01.05.2012 aligns with RoHS compliance — the part is free of the six original restricted substances. Surge voltage resistance rated at 6000 V — suitable for installation categories up to Cat III/IV in industrial environments.

Frequently asked questions

Will 3RV1021-1BA10-ZW96 drop into a panel specified for 3RV1011-1AA15?

Both are SIRIUS motor protection breakers with the same 45 mm width and snap-on DIN rail mounting, so the mechanical footprint is the same. However, the 3RV1021-1BA10-ZW96 is rated 2 A continuous vs the 3RV1011-1AA15's different current rating — verify the motor FLA and trip class match before substituting.
