The auxiliary switch is transversely designed and integrated, with ratings of 1 A at 24 V, 0.5 A at 230 V, and 0.15 A at 60 V, covering typical PLC input and contactor coil loads. Breaking capacity is a standout: 100 kA at 240 V, 400 V, 500 V, and 690 V AC. Phase failure detection is included; ground fault detection is not, so pair it with a separate ground-fault relay if that protection is needed. Width is 45 mm, height 97 mm, depth 96 mm — fits a standard 4-module-wide DIN slot. Mounting position is any orientation. Front protection class is IP20, so it's suited for enclosed panel use, not open washdown. Screw-type terminals for both main and auxiliary circuits: solid conductors accept 2x (0.5...1.5 mm²) and 2x (0.75...2.5 mm²); stranded accept 2x (1...2.5 mm²) and 2x (2.5...6 mm²). AWG equivalent for main contacts is 2x (14...10). Zero clearance needed at the back or sides — the breaker can be stacked directly against adjacent devices. Shock resistance is 25 g / 11 ms. The substance prohibition date (RoHS compliance) is 01.05.2012, indicating the part meets RoHS restrictions as of that date. Power dissipation in hot operating state at AC is 7.25 W — factor that into panel thermal calculations if multiple breakers are ganged. Maximum operating frequency at AC-3 duty is 15 operations per hour.","metaTitle":"Siemens 3RV1021-0JA15-ZW97 SIRIUS Motor Protection CB, 1A, C","metaDescription":"Siemens 3RV1021-0JA15-ZW97 SIRIUS motor protection circuit breaker, 1 A continuous, Class 10 trip, 100 kA breaking capacity at 400 V.

However, the 3RV2021-0HA15 is a higher-current variant (typically 1.6 A or above) with a different trip curve; verify the continuous current and motor power ratings match your load before substituting — the 1 A rating on the 3RV1021-0JA15-ZW97 is lower than most 3RV2021 variants."},{"question":"What compliance documentation does Siemens provide for 3RV1021-0JA15-ZW97?","answer":"The part carries a RoHS compliance date of 01.05.2012.
