Size S0 frame, three-pole, with screw-type terminals accepting 2×(1–2.5 mm²) solid/stranded or 2×(2.5–10 mm²) for the main circuit. ## Duty cycle and thermal behaviour Rated for 15 operations per hour at AC-3 duty. Total power loss is 8 W typical. Shock resistance tested at 25 g / 11 ms per IEC 60068-2-27, and surge voltage withstand is 6 kV — both figures confirm the breaker holds its settings and doesn't nuisance-trip under mechanical or electrical transients common in industrial refrigeration compressor starts.","metaTitle":"Siemens 3RV6021-4DA10 SIRIUS Motor Protection Circuit Breake","metaDescription":"Siemens 3RV6021-4DA10 SIRIUS motor protection circuit breaker, 25 A rated operational current, Class 10 trip, 690 V AC-3, DIN rail mount.
