The 187 kA breaking capacity at 240 V gives substantial fault-interrupt headroom for high-available-fault-current service-entrance or distribution panels; at 415 V and 440 V it still interrupts 121 kA, and at 500 V it interrupts 79 kA. Only at 690 V does the rating drop to 5.1 kA, so this frame is sized for 240–500 V distribution, not 690 V motor circuits. The basic switch without the UVR is order code 3VA2225-5HL32-0AA0. No auxiliary contacts or communication module are fitted on this variant. ## Panel fit and thermal management The maximum power loss of 50.5 W must be factored into enclosure thermal calculations, especially when the breaker is run near its 250 A rating in a sealed panel.","metaTitle":"Siemens 3VA2225-5HL32-0CA0 SENTRON MCCB, 250 A, 187 kA","metaDescription":"Siemens SENTRON 3VA2225-5HL32-0CA0 molded case circuit breaker, 250 A rated continuous current, 187 kA breaking capacity at 240 V, 3-pole, ETU320 release, undervoltage release, cur","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["Molded Case Circuit Breakers (MCCB)"],"specifications":{"Depth":"86 mm","Width":"105 mm","Height":"181 mm","at 240 V":"187 kA","at 415 V":"121 kA","at 440 V":"121 kA","at 500 V":"79 kA","at 690 V":"5.1 kA","at 40 °C":"250 A","at 45 °C":"250 A","at 50 °C":"250 A","at 55 °C":"241 A","at 60 °C":"232 A","at 65 °C":"222 A","at 70 °C":"213 A","Trip indicator":"No","Number of poles":"3","Product version":"Line protection","Voltage trigger":"No","lifecycle_stage":"current","Product brand name":"SENTRON","Product designation":"Molded case circuit breaker","Latching - endurance":"20 000","Undervoltage Release":"Yes","Communication Function":"No","Phase failure detection":"No","During Storage / Maximum":"80 °C","During Storage / Minimum":"-40 °C","Power loss [W] / maximum":"50.5 W","Auxiliary contact version":"Without","During Operation / Maximum":"70 °C","During Operation / Minimum":"-25 °C","Other Measurement Function":"No","Rated continuous current Iu":"250 A","Rated insulation voltage Ui":"800 V","Of The Supplied Basic Switch":"3VA2225-5HL32-0AA0","Design of the auxiliary release":"Undervoltage release (UVR)","Ground fault monitoring version":"Without","Of The Integrated Auxiliary Trip":"3VA9608-0BB24","Design of the overcurrent release":"ETU320","Protection class IP / on the front":"IP40","Reference code / acc. to DIN EN 81346-2":"Q","Adjustable response value time / tr max.":"15","Adjustable response value time / tr min.":"0.5","Undervoltage Release With Leading Contact":"No","Product extension / optional / motor drive":"Yes","Adjustable response value current / Ir max.":"250 A","Adjustable response value current / li max.":"2 500 A","Adjustable response value current / li min.":"375 A","Adjustable response value current / lr min.":"100 A","Neutral conductors / upgradeable/retrofittable":"No","Number of CO contacts / for auxiliary contacts":"0","Protective function of the overcurrent release":"LI","Switching capacity class of the circuit breaker":"M","Max. rated operational current of the frame size":"250 A","Max. rated operational voltage Ue with AC 50/60Hz":"690 V","Type of electrical connection / for main current circuit":"Lug terminal","Arrangement of electrical connectors / for main current circuit":"Front terminal","Type of connectable conductor cross-section, connection screw, width x thickness , max.":"25 x 8.5","Type of connectable conductor cross-section, connection screw, width x thickness , min.":"13 x 1 mm"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/6a7c0d29262bf1366bc093fc9653b1e6.pdf","sourceUrl":"https://support.industry.siemens.com/webbackend/api/ProductSupport/TechnicalData?language=en&region=cn&productId=240731&mlfb=3VA2225-5HL32-0CA0","alternativesUrl":"https://aoctrl.com/api/mcp/products/3VA2225-5HL32-0CA0/alternatives.json"},"ai":{"faq":[{"question":"Where can I buy 3VA2225-5HL32-0CA0 and what is the lead time?","answer":"This part is sourced and quoted to order through independent distribution.
