3RV1 vs 3RV2
| Item | 3RV1 (e.g. 3RV1011) | 3RV2 (e.g. 3RV2011) |
|---|---|---|
| Breaking capacity | 100 kA @ 690 VAC (same at all voltages) | 10–50 kA @ 690 VAC |
| GFC (ground-fault protection) | None | Yes (-15 suffix models, 15 mA) |
| Use | Heavy industry needing very high breaking capacity | General factories, where ground-fault protection is needed |
| Frame size | S00 (compact) | S0 (slightly larger, more accessories) |
Selection and installation tips
- CLASS 10 fast response: trips in 2–10 seconds at 10 times rated current, suited to normal induction motor starting current.
- Stacks directly with contactors: the 3RV series connects mechanically to Siemens 3RT2 contactors, saving external wiring.
- Current setting dial: fine-tune to the motor nameplate current after installation, without changing the model.
- Dial lock: some models (3RV1011-0JA1) come with a tamper-proof dial lock to prevent accidental adjustment.
