The Siemens SENTRON 3VA2225-5HN32-0CH0 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. At 415 V and 440 V the breaking capacity holds at 121 kA, dropping to 75.6 kA at 500 V and 4.5 kA at 690 V, so the voltage class of your distribution determines which rating governs the installation. This is a line-protection design (not motor-protection), so it is sized for feeder and main-breaker duty in switchboards, panelboards, and distribution enclosures. The continuous current rating remains flat at 250 A from 40 °C through 50 °C, then derates to 241 A at 55 °C, 232 A at 60 °C, 222 A at 65 °C, and 213 A at 70 °C — the thermal curve matters if the breaker sits in a hot enclosure or near other heat sources.
The 86 mm depth (3.39 in) includes the case body; verify projection past the panel door or gland plate if the enclosure is shallow.
Integrated accessories and releases
A trip indicator is present on the front face for quick visual fault identification. If you already have a 3VA2225-5HN32-0AA0 in the panel and need to add the UVR and auxiliary switches, the 0CH0 variant is the factory-assembled version of that same base with those options installed.
Ground-fault monitoring is not fitted on this variant.
