Screw fixing to the backplate is the standard mount; the mounting surface can tilt +/-10° from vertical. Ventilation gaps are mandatory: 100 mm above, 75 mm below, 10 mm forward, 5 mm to the side, and 0 mm backward. Without these clearances, the internal heatsink cannot shed the IGBT losses and the unit derates prematurely. Shock tolerance is 15 g / 11 ms. ## Motor protection and trip class Trip Class 10A is the default setting per IEC 60947-4-2, with selectable 10E and 20E profiles. Minimum settable current is 11.5 A, which sets the lower bound of the motor FLA it can protect. The minimum load is 15 % of the smallest settable Ie. ## Fieldbus and control integration The 3RW5215-3TC14 supports PROFIBUS, Modbus RTU, Modbus TCP, EtherNet/IP, and PROFINET. PROFIenergy is available with the PROFINET communication module. Firmware updates are supported in the field. An error logbook is accessible with special accessories. Auto-reset and remote reset by cycling the control supply voltage are standard. ## Wiring terminals and power connections Solid wire terminations accept two conductors per clamp: 1.0...2.5 mm² for control circuits, and 2.5...10 mm² for the main power path. Rated supply voltage is 200...480 V at 50/60 Hz. ## Approvals and compliance documentation The product category is hybrid switching devices.","metaTitle":"Siemens 3RW5215-3TC14 Soft Starter, 200-480 V, 11.5 A","metaDescription":"Siemens 3RW5215-3TC14 soft starter, rated 200-480 V, 11.5 A min, Trip Class 10A per IEC 60947-4-2.
