AC-3e is the enhanced version of AC-3, covering standard squirrel-cage motors with occasional inrush; the 65 A figure governs the continuous motor current the contactor can switch without derating. The 24 V AC 50 Hz coil keeps control transformer sizing straightforward in panels where AC control voltage is already present. Termination is mixed: screw terminals on the main circuit for high-current power wiring, spring-loaded terminals on the control and auxiliary circuit for faster wiring of the coil and aux contacts. The built-in 1 NO + 1 NC auxiliary contact block covers basic feedback and interlocking without an add-on module. Size S2 means it occupies a standard DIN-rail footprint and aligns with Siemens S2 busbar and accessory system for panel integration.","metaTitle":"Siemens 3RT2037-3AB00-Z X95 Power Contactor, 65 A AC-3e, 30","metaDescription":"Active Siemens 3RT2037-3AB00-Z X95 power contactor. 65 A AC-3e/AC-3, 30 kW / 400 V, 3-pole, 24 V AC 50 Hz coil, 1 NO + 1 NC aux, screw main / spring-loaded control terminals, size","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Contactors"],"specifications":{"title":"3RT2037-3AB00-Z X95","Group Code":"R711","description":"power contactor, AC-3e/AC-3, 65 A, 30 kW / 400 V, 3-pole, 24 V AC, 50 Hz, auxiliary contacts: 1 NO + 1 NC, main circuit: screw terminal, control and auxiliary circuit: spring-loaded terminal, size: S2, reusable packaging, pack = 30 units","Product Group":"5338","Product class":"A: Standard product which is a stock item could be returned within the returns guidelines/period.","Quantity Unit":"1 Piece","Product Family":"Ordering Data Overview","lifecycle_stage":"current","Packaging Quantity":"1","Export Control Regulations":"AL : N / ECCN : N","Packaging dimensions (L x W x H)":"122.5 x 62.00 x 142.00 mm","Compliance with the substance restrictions according to RoHS directive":"Since: 01-10-14","REACH Art. 33 Duty to inform according to the current list of candidates":"Reach Information"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/de5e4f6940158dde7a0ebe335508604e.pdf","sourceUrl":"https://sieportal.siemens.com/en-ae/products-services/detail/3RT2037-3AB00-ZX95?tree=CatalogTree"},"ai":{"faq":[{"question":"What compliance documentation is available for this contactor?","answer":"RoHS compliance effective since October 1, 2014, and REACH Article 33 candidate-list information is published.
