Breaking capacity is 100 kA at 240 V and 400 V AC, dropping to 42 kA at 500 V and 6 kA at 690 V. If one phase drops out, the breaker trips — preventing single-phasing damage to the motor. Ground fault detection is not included, so for applications requiring GF protection, an external module or separate GF relay is needed. Main circuit connections are screw-type terminals. Solid and stranded conductors: 2x (1 … 2.5 mm²) or 2x (2.5 … 6 mm²) per terminal. AWG equivalents for main contacts: 2x (14 … 10). No auxiliary contacts are factory-fitted, but an auxiliary switch can be added. ## Environmental and Durability Shock resistance rated at 25 g for 11 ms. Mechanical endurance of the main contacts is typically 100,000 operations.","metaTitle":"Siemens 3RV1021-1JA10-ZW97 SIRIUS Motor Protection Circuit B","metaDescription":"Siemens 3RV1021-1JA10-ZW97 SIRIUS motor protection circuit breaker. 10 A continuous, 4 kW at 400 V, CLASS 10 trip, 100 kA breaking at 400 V.

This high interrupting rating allows it to be used as a main branch protector without requiring upstream current-limiting fuses in most industrial panels."},{"question":"What does CLASS 10 trip mean for motor protection?","answer":"CLASS 10 means the breaker will trip within 10 seconds at 7.2 times the rated current. This is fast enough to protect standard induction motors during a locked-rotor condition while allowing normal starting inrush without nuisance trips."},{"question":"Does this breaker include phase failure protection?","answer":"Yes, phase failure detection is built in. If one phase is lost, the breaker trips to prevent single-phasing damage to the motor."},{"question":"How do I get pricing and availability for 3RV1021-1JA10-ZW97?","answer":"This part is sourced to order against an RFQ through independent distribution.
