This breaker includes phase failure detection, which opens the circuit if one phase drops out — critical for preventing single-phasing damage on three-phase motor loads. The front panel carries an IP20 rating, so it's touch-safe once installed in an enclosure, but not rated for washdown environments. The screw-type terminals on the main circuit accept 2x (1... 2.5 mm²) solid or stranded, or 2x (2.5... 6 mm²) — fine for the 16 A rating with standard panel wire. Auxiliary and control circuits use the same screw terminal style. No backward or side clearance is required, so it can be packed tight on the rail. Rated breaking capacity varies with voltage: 100 kA at 240 V AC, 50 kA at 400 V AC, 10 kA at 500 V AC, and 4 kA at 690 V AC. The 690 V rating drops to 4 kA, so at higher voltages coordination with a backup fuse or upstream breaker should be checked. Shock resistance is rated at 25 g for 11 ms. The product complies with RoHS substance prohibitions as of May 1, 2012.","metaTitle":"Siemens 3RV1021-4AA10-ZW96 SIRIUS Motor Protection Circuit B","metaDescription":"Siemens 3RV1021-4AA10-ZW96 SIRIUS motor protection circuit breaker, 16 A continuous, CLASS 10 trip, 50 kA breaking at 400 V.
