The S0 frame size (45 mm wide, 97 mm tall, 96 mm deep) fits standard motor control center buckets and small panel enclosures. Screw-type terminals on both main and auxiliary circuits accept 2×(0.5…1.5 mm²) or 2×(0.75…2.5 mm²) solid/stranded, or AWG equivalents. Main contact torque spec: 2…2.5 N·m. ## Electrical and environmental ratings Rated operational current 40 A at AC-3 duty (motor switching), with a maximum operating frequency of 15 operations per hour at that load. Rated insulation voltage 690 V, surge voltage resistance 6 kV. Power dissipation 14 W typical. Relative humidity 10…95 %. Shock rated at 25 g / 11 ms per IEC 60068-2-27.","metaTitle":"Siemens 3RV6021-4FA15 SIRIUS Motor Protection Circuit Breake","metaDescription":"Siemens SIRIUS 3RV6021-4FA15 motor protection circuit breaker, 40 A rated current, CLASS 10 trip, 690 V, 3-pole, S0 size.
