Depth is 96 mm, height 97 mm — fits standard distribution boards without crowding the gland plate. ## Breaking capacity and duty cycle Rated short-circuit breaking capacity holds at 100 kA across the voltage range: 240 V, 400 V, 500 V, and 690 V AC. That's consistent fault clearance regardless of supply voltage within the rated range. Maximum operating frequency is 15 operations per hour at AC-3 duty — fine for motor starting, not for rapid cycling. Power dissipation is 5.5 W hot, 1.8 W per pole, so derating in a sealed enclosure is worth checking if you're packing multiple units.","metaTitle":"Siemens 3RV1021-0EA10-ZW96 SIRIUS Motor Protection Circuit B","metaDescription":"Siemens 3RV1021-0EA10-ZW96 SIRIUS motor protection circuit breaker, 0.4 A rated current, Trip Class 10, 100 kA breaking capacity at 400 V AC.
