The Siemens SENTRON 3VA2225-6JP32-0HH0 is a 3-pole molded case circuit breaker (MCCB) rated for 250 A continuous current at 40 °C, designed for line protection in distribution panels. Its interrupting capacity reaches 242 kA at 240 V and 187 kA at 415 V, giving it the headroom to handle high-fault scenarios downstream of a transformer or on a large bus. The 105 mm width and 181 mm height fit standard SENTRON panel footprints, and the 86 mm depth leaves clearance for rear-connected busbars.
Ratings and what they mean for your panel
The 250 A continuous rating holds steady from 40 °C up to 50 °C — no derating needed in a warm enclosure. Above that, the curve drops to 238 A at 55 °C and 200 A at 70 °C, which matters if the breaker sits near transformers or drives that raise ambient temperature. The maximum breaking capacity of 2 500 A and minimum of 375 A define the trip unit's adjustment range for short-circuit and overload protection, letting you coordinate with downstream feeders. Power loss is listed at 48 W maximum — a figure to consider for enclosure thermal calculations when multiple breakers are ganged. The operating temperature range spans -25 °C to 70 °C, with storage from -40 °C to 80 °C, covering unheated warehouses and outdoor cabinets.
Auxiliaries and integration
This variant ships with a shunt trip (STL) release and a configuration of 2 auxiliary switches plus 1 trip alarm switch (HQ). The communication function is onboard, meaning it can report status and trip events to a higher-level control system without an external module. A voltage trigger is present; undervoltage release is not included. Ground-fault monitoring is absent on this version — specify the -6JP32-0HH0 with the GF option if that is required.
