The Siemens SENTRON 3VA2225-5HL32-0HC0 is a 3-pole molded case circuit breaker rated for 250 A continuous current at 40 °C, designed for line protection in distribution panels. That 250 A holds flat through 50 °C — only starts derating above that, hitting 213 A at 70 °C, so you don't lose headroom in a warm enclosure. Breaking capacity is the headline: 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 4.5 kA at 690 V. That 187 kA at 240 V covers high-fault utility feeds; the 121 kA at 415 V handles most industrial motor branch circuits without cascading upstream. At 690 V the 4.5 kA still clears a bolted fault on a 690 V drive bus.
Dimensions are 105 mm wide, 181 mm tall, 86 mm deep — standard SENTRON 3VA2 footprint.
