Product details

Rated for 20 to 690 V, it delivers 100 kA short-circuit breaking capacity at 240 V and 400 V AC, meaning it can interrupt a fault up to that level without upstream devices needing to clear it — a key spec for SCCR coordination in industrial panels.

Dimensions are 97 mm deep, 45 mm wide, and 97 mm tall, with 50 mm clearance needed above and below, 30 mm to the side, and zero clearance forward or backward. Main circuit terminals accept 2x 1 to 2.5 mm² or 2x 2.5 to 10 mm² solid or stranded wire, with M4 screw terminals for the main contacts.

Frequently asked questions

Does 3RV2021-1FA10-ZW96 detect phase failure?

Yes, phase failure detection is included — it trips if one phase drops out on a three-phase motor.

What mounting options does 3RV2021-1FA10-ZW96 support?

Screw mounting or snap-on onto 35 mm DIN rail per DIN EN 60715, in any mounting position.
