The Siemens SENTRON 3VA2225-5JQ32-0BH0 is a 3-pole molded case circuit breaker (MCCB) rated for line protection, carrying 250 A continuously at 40 °C and derating to 200 A at 70 °C. It breaks up to 187 kA at 240 V, 121 kA at 415/440 V, and holds a 4.5 kA rating at 690 V — so the interrupting capacity scales with your system voltage, not a single headline number.
Above that, the thermal curve pulls back: 238 A at 55 °C, 225 A at 60 °C, 213 A at 65 °C, 200 A at 70 °C. That derating matters for coordination studies. The adjustable thermal-magnetic trip (initial value 50 A, full-scale 250 A) lets you set the overload threshold within that range, so one breaker frame covers a spread of load sizes. The trip indicator confirms the breaker opened on fault, not manual operation. Breaking capacity: 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, 4.5 kA at 690 V. For a 480 V system (common in North America), the relevant figure is the 500 V row at 75.6 kA — that's the SCCR the breaker can interrupt without welding or rupturing. At 690 V the capacity drops sharply to 4.5 kA, so it's not a universal high-voltage breaker; it's sized for distribution up to 500 V.
Auxiliaries and integration
The auxiliary switches report position (open/closed/tripped) to a PLC or status lamp. Communication function is built in, so it can talk to a higher-level system via the SENTRON communication modules or PROFIBUS/PROFINET gateway for remote monitoring and trip-event logging.
Physical fit and panel considerations
Dimensions: 181 mm high, 105 mm wide, 86 mm deep (7.13 x 4.13 x 3.39 in). No need to re-drill the panel if you're swapping between 3VA2 variants of the same frame. The storage range is wider because the breaker isn't dissipating heat when stored — that's the handling limit, not the running limit.
