MCCB for high-fault panels
The Siemens SENTRON 3VA2225-6JP32-0HL0 is a 3-pole molded case circuit breaker rated for 250 A continuous at 40 °C. Its interrupting ratings are substantial: 242 kA at 240 V and 187 kA at both 415 V and 440 V, dropping to 121 kA at 500 V and 4.5 kA at 690 V. This is a line-protection design — no ground-fault monitoring, no undervoltage release — but it carries a shunt trip (STL) and a communication function for integration into a higher-level system. The auxiliary switch configuration includes 2 auxiliary switches, 1 trip alarm switch, and 1 electrical alarm switch (HQ).
Thermal derating matters here
The 250 A rating holds flat from 40 °C to 50 °C. Above that, derate: 238 A at 55 °C, 225 A at 60 °C, 213 A at 65 °C, 200 A at 70 °C. If the panel ambient runs hot, size the load accordingly — the breaker won't trip early, but the continuous current capability drops. Maximum power loss is 48 W, which factors into enclosure ventilation planning. Dimensions are 181 mm high, 105 mm wide, 86 mm deep — standard 3-pole MCCB footprint for DIN-rail or screw-mount panel integration.
Current production, no lifecycle concern
Current-production part. Basic switch variant is 3VA2225-6JP32-0AA0; the -0HL0 suffix adds the communication function and auxiliary switch complement.
Panel fit versus sibling 3VA2116-5JP32-0AE0
The 3VA2116-5JP32-0AE0 is a lower-current sibling in the same 3VA family. The key difference for panel drop-in: the 3VA2225-6JP32-0HL0 is physically larger (181 x 105 x 86 mm vs the 3VA2116's smaller frame) and carries a higher continuous rating. It will not drop into a panel cutout sized for the 3VA2116 without enlarging the mounting footprint. Both share the SENTRON platform and the same auxiliary switch options, but the frame size and busbar spacing differ.
