The Siemens SENTRON 3VA2225-5KP32-0DL0 is a 3-pole molded case circuit breaker rated for 250 A continuous current at 40 °C, with a maximum breaking capacity of 187 kA at 240 V AC and 121 kA at 415 V AC. It's designed for line protection in industrial distribution panels, and the 187 kA SCCR at 240 V means it can safely interrupt fault currents up to that level without cascading upstream — critical for high-fault installations like transformer secondaries or large motor control centers.
The 3VA2225-5KP32-0DL0 mounts on a DIN rail or panel-mount via the SENTRON base. Dimensions are 105 mm wide, 181 mm tall, 86 mm deep — fits standard MCCB slots in switchgear cubicles. The supplied basic switch is 3VA2225-5KP32-0AA0; auxiliary switch configuration includes 2 auxiliary switches plus 1 trip alarm and 1 electrical alarm switch (HQ type), and the undervoltage release (UVR) is built in. Communication function is integrated, so it can report status to a PLC or BMS without an add-on module.
Thermal derating is published: holds 250 A from 40 °C to 50 °C, then drops to 238 A at 55 °C, 225 A at 60 °C, 213 A at 65 °C, and 200 A at 70 °C. Operating temperature range is -25 °C to 70 °C; storage range is -40 °C to 80 °C. Maximum power loss is 50.5 W. No ground-fault monitoring version is included — this is a straight line-protection breaker with overcurrent and short-circuit trip only.
