Breaking capacity is rated 100 kA at 240 V, 400 V, and 500 V, and 4 kA at 690 V. No ground fault detection on this variant, so if your process requires GF protection, you will need an external module or a different 3RV2 variant. Rated insulation voltage is 20 to 690 V, covering most low-voltage motor circuits worldwide. The thermal setting range is not listed in this excerpt, but the unit is sized to match the motor full-load current — confirm the adjustable range on the nameplate before committing the BOM line.
The breaker is 45 mm wide, 106 mm tall, and 97 mm deep — a standard 45 mm modular width that fits most DIN-rail enclosures without crowding. Required clearances: 50 mm above and below, 30 mm to the side, and zero forward or backward clearance needed. That zero forward clearance means you can butt the breaker against a panel door or backplane without derating, which simplifies layout in shallow enclosures.
