It is configured as a line protection device, meaning it is intended for feeder or main breaker duty in distribution panels, not for direct motor starting. Breaking capacity is 440 kA at 240 V, 330 kA at 415 V and 440 V, 220 kA at 500 V, and 52.5 kA at 690 V — figures that place it in the high-interrupting category for industrial switchgear where fault currents can be severe. Physical footprint: 181 mm height, 105 mm width, 86 mm depth. Above that, derating applies: 238 A at 55 °C, 225 A at 60 °C, 213 A at 65 °C, and 200 A at 70 °C. The ETU850 electronic trip unit provides adjustable long-time, short-time, instantaneous, and ground-fault protection (though this variant ships without ground-fault monitoring). Communication function and other measurement functions are present, enabling integration with energy management systems.","metaTitle":"Siemens 3VA2225-8KP32-0AA0 SENTRON MCCB, 250 A, 3-Pole, ETU8","metaDescription":"Siemens SENTRON 3VA2225-8KP32-0AA0 molded case circuit breaker, 250 A continuous, 3-pole, ETU850 electronic trip.
