The SENTRON 3VA2325-5HN32-0BH0 is a 3-pole molded case circuit breaker rated for 250 A continuous current across the full ambient range from 40 °C to 70 °C — no derating needed until you push past that window. Breaking capacity sits at 187 kA at 240 V, dropping to 121 kA at 415/440 V, 75.6 kA at 500 V, and 7.5 kA at 690 V. The 187 kA figure at 240 V is the headline number for service-entrance or main-feeder duty on a 240/120 V delta or 208Y/120 V wye secondary. The UVR drops the breaker on loss of control voltage, which is standard for emergency-off circuits and undervoltage protection schemes.
That's a standard SENTRON 3VA2 frame footprint — fits the same mounting base and busbar system as other 250 A frames in the family. Panel builders should verify the busbar adapter and lug kit separately; those are ordered as accessories, not included in the base breaker order code.
