At 415 V and 440 V the interrupting rating drops to 242 kA, and at 690 V it is 6.3 kA — the voltage derating is steep, so verify the available fault current at your system voltage before specifying. The ETU850 electronic trip unit provides adjustable long-time, short-time, instantaneous, and ground-fault protection curves — this is a fully programmable trip, not a fixed thermal-magnetic, so coordination studies can be tuned without swapping the breaker. ## Integration dimensions and auxiliaries ## Thermal derating and ambient limits Above 50 °C it derates linearly: 238 A at 55 °C, 225 A at 60 °C, 213 A at 65 °C, and 200 A at 70 °C. The maximum operating ambient is 70 °C, minimum -25 °C. Maximum power loss is 48 W — account for this in enclosed panel heat calculations, especially when multiple breakers are ganged in a single enclosure.","metaTitle":"Siemens 3VA2225-7KP32-0KH0 SENTRON MCCB, 250 A, 330 kA at 24","metaDescription":"Siemens SENTRON 3VA2225-7KP32-0KH0 molded case circuit breaker, 250 A rated, 330 kA interrupting at 240 V.
