Its interrupting capacity hits 75.6 kA at 240 V, dropping to 52.5 kA at 415 V and 32 kA at 440 V — numbers that matter when you're coordinating downstream branch protection and need the SCCR to hold under fault. Max power loss is 10.6 W, which is manageable for enclosure thermal budgeting. The 32 A rating holds across ambient temperatures from 40 °C through 50 °C without derating; at 55 °C it drops to 31 A, and at 70 °C to 30 A. That's a standard line-protection characteristic, not a motor-protection curve. The 75.6 kA interrupting rating at 240 V gives solid selectivity headroom for a 22 kA or 25 kA available fault current at the panelboard; at 480 V the 52.5 kA still covers most industrial services. ## Panel integration The 130 mm height clears most enclosure gutters. Two auxiliary switches (HP design) are built in, so you can wire status feedback without an add-on module.","metaTitle":"Siemens 3VA1132-3EF36-0AB0 SENTRON MCCB, 32 A, 75.6 kA","metaDescription":"Siemens SENTRON 3VA1132-3EF36-0AB0 molded case circuit breaker, 32 A at 40 °C, 75.6 kA interrupting at 240 V, 3-pole, TM240 release, active production, sourced to order.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["Molded Case Circuit Breakers (MCCB)"],"specifications":{"Depth":"70 mm","Width":"76.2 mm","Height":"130 mm","Maximum":"0 A","Minimum":"0 A","at 240 V":"75.6 kA","at 415 V":"52.5 kA","at 440 V":"32 kA","at 500 V":"11.9 kA","at 690 V":"11.9 kA","at 40 °C":"32 A","at 45 °C":"32 A","at 50 °C":"32 A","at 55 °C":"31 A","at 60 °C":"31 A","at 65 °C":"30 A","at 70 °C":"30 A","Depth [In]":"2.76 in","Width [In]":"3 in","Height [In]":"5.12 in","Trip Indicator":"No","Number Of Poles":"3","Voltage Trigger":"No","lifecycle_stage":"current","Product Brand Name":"SENTRON","Product Designation":"Molded case circuit breaker","Undervoltage Release":"No","Design Of The Product":"Line protection","Communication Function":"No","During Storage / Maximum":"80 °C","During Storage / Minimum":"-40 °C","power loss [W] / maximum":"10.6 W","During Operation / Maximum":"70 °C","During Operation / Minimum":"-25 °C","Other Measurement Function":"No","Of The Supplied Basic Switch":"3VA11323EF360AA0","Design Of The Auxiliary Switch":"2 auxiliary switches HP","Ground-Fault Monitoring Version":"Without","Insulation Voltage / Rated Value":"800 V","Design Of The Overcurrent Release":"TM240","Design Of Short-Circuit Protection":"For switching power values in DC networks, see the 3VA molded case circuit breaker device manual; link to be found under Service & Support in the last chapter","protection class IP / on the front":"IP40","Product Function / Grounding Protection":"No","operating voltage / at AC / rated value":"690 V","operating voltage / at DC / rated value":"500 V","reference code / according to IEC 81346-2":"Q","Product Extension / Optional / Motor Drive":"Yes","Protection Function Of The Overcurrent Release":"LI","number of CO contacts / for auxiliary contacts":"2","Of The Integrated Auxiliary Switch/Alarm Switch":"3VA9988-0AA11","Switching Capacity Class Of The Circuit Breaker":"N","Mechanical Service Life (Operating Cycles) / Typical":"20 000","Type Of Electrical Connection / For Main Current Circuit":"box terminal on both sides","Arrangement Of Electrical Connectors / For Main Current Circuit":"Front terminal"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/c3de18f10dd52266f770fd73388f1ee5.pdf","sourceUrl":"https://support.industry.siemens.com/webbackend/api/ProductSupport/TechnicalData?language=en&region=cn&productId=177142&mlfb=3VA1132-3EF36-0AB0","alternativesUrl":"https://aoctrl.com/api/mcp/products/3VA1132-3EF36-0AB0/alternatives.json"},"ai":{"faq":[{"question":"Where can I buy 3VA1132-3EF36-0AB0 and what is the lead time?","answer":"Sourced and quoted to order against an RFQ through independent distribution.
