Breaking capacity reaches 100 kA across the full voltage range (240 V through 690 V AC), so it can interrupt worst-case fault currents without upstream coordination — a rare spec for a 45 mm wide device. Built-in phase-failure detection trips the breaker if one phase drops out, preventing single-phasing damage to the motor. No ground-fault detection on this variant. ## Panel Integration & Mounting Mounting position any; no derating for side-by-side placement (0 mm clearance required at sides and rear). Screw-type terminals on both main and auxiliary circuits accept solid or stranded conductors: 2×(1…2.5 mm²) and 2×(2.5…6 mm²) per clamp, or AWG 14–10. RoHS compliance date 01.05.2012 confirms the part meets EU substance restrictions. Ambient operating range -20…+60 °C; storage/transport -50…+80 °C. ## Duty Cycle & Thermal Management Maximum operating frequency in AC-3 duty is 15 operations per hour — adequate for motor starting on pumps, fans, and compressors, but not for high-cycling applications like rapid reversing. Power dissipation at rated current: 7.25 W total, 2.4 W per pole in hot operating state. Rated impulse withstand voltage 6 kV, shock resistance 25 g / 11 ms — suitable for industrial environments with transient surges and mechanical vibration.","metaTitle":"Siemens 3RV1021-0JA10-ZW98 SIRIUS Motor Circuit Breaker, 1 A","metaDescription":"Siemens 3RV1021-0JA10-ZW98 SIRIUS motor-protective circuit breaker, 1 A continuous, Class 10 trip, 100 kA breaking capacity at 400 V.
