The 45 mm wide, 97 mm tall, 96 mm deep footprint fits standard panel layouts with zero clearance at the sides and rear. For a motor, match this to the nameplate FLA. The 7.5 kW at 400 V AC-3 rating is the practical motor sizing guide: this breaker is sized for a 7.5 kW, 400 V three-phase motor in a standard starting duty. The 690 V rated insulation voltage (Ui) confirms it can be used on 480/600 V systems with the appropriate coordination. Power dissipation at rated current is 9.25 W total, 3.1 W per pole in hot operating state. This matters for thermal management in a sealed enclosure — account for it in the cabinet cooling budget. Any mounting position is allowed. Zero clearance at the sides and rear simplifies panel layout — no derating for side-by-side installation on the rail. Screw-type terminals accept solid or stranded conductors: 2x (1... 2.5 mm²) and 2x (2.5... 6 mm²) per terminal, or AWG 14-10 for the main contacts. The auxiliary switch slot is available (product extension auxiliary switch is supported), so you can add a remote status contact without replacing the breaker.","metaTitle":"Siemens 3RV1021-4AA10-ZW98 SIRIUS Motor Protection Circuit B","metaDescription":"Siemens 3RV1021-4AA10-ZW98 SIRIUS motor protection circuit breaker, 16 A continuous, Class 10 trip, 7.5 kW at 400 V.
