The Siemens SENTRON 3VA2225-5JP32-0DH0 is a 3-pole molded case circuit breaker rated for 250 A continuous current at 40 °C, with an ETU550 electronic trip unit for adjustable protection curves. It breaks up to 187 kA at 240 V, so it handles high-fault-current service-entrance and distribution applications where upstream coordination demands a high interrupting rating. The ETU550 trip unit supports LSIG protection (long-time, short-time, instantaneous, ground-fault) with adjustable pickups and time delays — typical for feeder breakers protecting transformers, busways, or large motor control centers.
Interrupting ratings climb as voltage drops: 187 kA at 240 V, 121 kA at both 415 V and 440 V, 79 kA at 500 V, and 5.1 kA at 690 V.
At 55 °C it drops to 238 A, at 60 °C to 225 A, at 65 °C to 213 A, and at 70 °C to 200 A. If your panel ambient runs 55 °C or higher, factor the reduced continuous current into your load schedule.
Auxiliary and communication options
The communication function is present, meaning it can integrate with a BMS or SCADA via the SENTRON communication platform.
That 105 mm width is standard for a 3-pole SENTRON 3VA2 frame — it fits the same mounting footprint as other 3VA2 250 A breakers. Trip indicator is visible through the front cover, so a quick glance tells you if it's tripped without opening the door.
