The Siemens SENTRON 3VA2225-5HL32-0KH0 is a 3-pole molded case circuit breaker (MCCB) rated at 250 A continuous current at 40 °C, with the ETU320 electronic trip unit. That 250 A holds flat through 50 °C — above that it derates to 241 A at 55 °C, 232 A at 60 °C, 222 A at 65 °C, and 213 A at 70 °C. Interrupting capacity is 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 drop to 4.5 kA at 690 V means it is not the breaker for a 690 V motor branch with high available fault current — check the point-on-wave coordination study before committing. The ETU320 is an electronic trip — adjustable thermal-magnetic curves are not what you get here. This unit is line-protection version, no ground-fault monitoring, no undervoltage release, no communication module.

Frequently asked questions
What trip unit does this MCCB use?
The ETU320 electronic trip unit. It is an LSIG or LSI programmable release depending on configuration — not a fixed thermal-magnetic. This variant is line-protection version with no ground-fault monitoring.
