Rated for a 2.2 kW motor at 400 V AC, it handles the typical 4-pole induction motor load on a 400 V three-phase line. This breaker delivers 100 kA breaking capacity at 240 V, 400 V, and 500 V AC, dropping to 6 kA at 690 V AC. That gives the panel builder headroom for high-SCCR installations without cascading coordination. The 7.25 W power dissipation in hot operating state (at rated current) is modest enough that thermal derating in a crowded enclosure is rarely a concern. Mounting position is any, so vertical or horizontal DIN-rail orientation does not affect the trip curve. The main terminals accept 2× (0.5…1.5 mm²) solid or 2× (1…2.5 mm²) stranded; the auxiliary switch terminals accept 2× (0.75…2.5 mm²) solid or 2× (2.5…6 mm²) stranded. AWG equivalents for the main contacts are 2× (14…10). The auxiliary switch is transverse design and field-addable, so you can wire a remote status signal without replacing the breaker. No last-time-buy or discontinuation notice applies. Substance prohibitance per the RoHS-like declaration dates to 01.05.2012, which aligns with the EU RoHS recast. The storage and transport temperature range of -50 to +80 °C and operating range of -20 to +60 °C cover most plant-floor environments without special handling.","metaTitle":"Siemens 3RV1021-1GA15-ZW95 SIRIUS Motor Protection Circuit B","metaDescription":"Siemens SIRIUS 3RV1021-1GA15-ZW95 motor protection circuit breaker, 6.3 A continuous, CLASS 10 trip, 100 kA breaking at 400 V.
