SENTRON 3VA2225-7HL32-0JH0 — 250 A MCCB for Line Protection
The Siemens SENTRON 3VA2225-7HL32-0JH0 is a 3-pole molded case circuit breaker (MCCB) rated for 250 A continuous current and designed for line protection. Its interrupting capacity reaches 330 kA at 240 V AC, 242 kA at 415 V and 440 V, 187 kA at 500 V, and 4.5 kA at 690 V — figures that define the available fault current it can safely clear without upstream cascading. The breaker carries a trip indicator and a voltage trigger, with 2 auxiliary switches plus 1 trip alarm switch (HQ design) and a shunt trip release (STL) for remote opening. No undervoltage release or ground-fault monitoring is fitted on this variant.
Thermal Derating and Panel Fit
The 250 A rating holds flat from 40 °C through 50 °C ambient, then derates to 241 A at 55 °C, 232 A at 60 °C, 222 A at 65 °C, and 213 A at 70 °C. For a panel OEM or MRO planner slotting this into an existing enclosure, the dimensions are 105 mm wide, 181 mm high, and 86 mm deep — a 3-pole footprint that drops into a standard SENTRON 3VA mounting base without rewiring from the 3VA2116-5JP32-0AE0 or other 3VA frame siblings, provided the busbar and lug kit match the 250 A continuous rating.
