The Siemens SENTRON 3VA2225-5HL32-0KC0 is a 3-pole molded case circuit breaker (MCCB) rated for 250 A continuous current at 40 °C, with a maximum interrupting capacity of 187 kA at 240 V AC. At 415 V and 440 V it holds 121 kA, dropping to 75.6 kA at 500 V and 4.5 kA at 690 V. For a procurement decision: the 250 A frame gives you headroom on a 200 A feeder without stepping up to a 400 A frame, and the 187 kA SCCR at 240 V means this breaker can be applied on service-entrance or high-fault panels where the available fault current exceeds 100 kA — a common requirement in industrial switchboards. The continuous current derates linearly above 55 °C: 241 A at 55 °C, 232 A at 60 °C, 222 A at 65 °C, 213 A at 70 °C (–). If your panel ambient is 60 °C, you lose 18 A from the nameplate; plan your load accordingly.
Built-in accessories and function
No undervoltage release is fitted, and there is no ground-fault monitoring module. The design is line protection — thermal-magnetic or electronic trip curve suited for feeder and main breaker duty, not motor protection. The breaker ships with basic switch order code 3VA2225-5HL32-0AA0.
The 105 mm width is three 35 mm DIN-module spaces, so it occupies the same panel cut-out as other 3-pole 3VA2 breakers. If you are replacing a different-brand 250 A MCCB, check the mounting hole pattern and bus-bar spacing — the SENTRON uses a fixed front-connect lug arrangement.
