The 100 kA figure covers most industrial distribution panels fed from a transformer of several hundred kVA — it interrupts a bolted fault without the upstream fuse or breaker needing to clear. At 690 V the 6 kA rating still handles the majority of motor-starting faults in 690 V systems. Width is 45 mm. Any mounting position allowed. Terminals accept 1 to 6 mm² solid or stranded wire (two conductors per clamp), or AWG 14 to 10. The screw terminals are the same type for main and auxiliary circuits, so the wireman uses one tool. IP20 on the front — protected against finger contact, not for washdown areas. The -ZW98 suffix indicates a special version (customer-specific variant). Verify the exact configuration against your BOM — the base electrical ratings (6.3 A, Class 10, 100 kA) are standard, but the ZW code may carry a factory-set thermal adjustment or accessory package that differs from the standard 3RV1021-1GA10.","metaTitle":"Siemens 3RV1021-1GA10-ZW98 SIRIUS Motor Protection Circuit B","metaDescription":"Siemens SIRIUS 3RV1021-1GA10-ZW98 motor protection circuit breaker, 6.3 A continuous, Class 10 trip, 100 kA breaking at 400 V.

The -ZW98 variant may carry a factory-preset thermal setting or special accessory configuration. If your application doesn't require the ZW customization, the base part is a drop-in replacement.
