The 45 mm width (3 TE) and 96 mm depth fit standard distribution boards. Screw terminals on both main and auxiliary circuits accept 2x (1…2.5 mm²) solid or stranded, or 2x (2.5…6 mm²) — no special ferrules needed for the larger range. Shock rated at 25g / 11 ms, surge voltage withstand at 6 000 V — suitable for industrial environments with moderate vibration and transient events. Operating frequency is limited to 15 operations per hour at AC-3 duty — fine for motor starting cycles but not for frequent switching applications.","metaTitle":"Siemens 3RV1021-1JA10 SIRIUS Motor Circuit Breaker, 10 A, CL","metaDescription":"Siemens SIRIUS 3RV1021-1JA10 motor protection circuit breaker. 10 A continuous, CLASS 10 trip, 100 kA at 400 V AC.
