The 3RW5236-2TC04: Rated for 200 to 480 V supply — covers common low-voltage three-phase networks across most industrial regions without a transformer tap. Minimum settable current is 81 A, meaning the soft starter can be configured down to that floor for smaller motors; the upper limit is set by the unit's full-load rating (not listed here, but the 81 A floor tells you this is a mid-range SIRIUS frame). ## Fieldbus and control integration Built-in PROFIBUS, Modbus RTU, Modbus TCP, EtherNet/IP, and PROFINET — no separate communication module needed for these five protocols, which covers the vast majority of PLC networks in European and North American plants. PROFIenergy support is present when paired with the PROFINET standard communication module, allowing the soft starter to participate in energy-management shut-down sequences during idle periods. Remote reset is possible by cycling the 24 V control supply — useful for unattended restart after a fault without a physical panel visit. ## Mounting and environmental limits Clearance requirements: 100 mm above, 75 mm below, 10 mm front, 5 mm sides, 0 mm rear — the tight rear clearance means it can sit flush against a backpanel, but the 100 mm top gap is non-negotiable for airflow and cable bend radius. Shock resistance is 15 g / 11 ms, dropping to 12 g / 11 ms if contact lifting is a concern — adequate for most industrial floor installations but not for shipboard or mobile equipment without additional damping. ## Approvals and compliance documentation Carries UL, CSA, and CE marking — accepted for panel builds destined for North America and the European Economic Area without additional agency review. Pollution degree 3 per IEC 60947-4-2 means it is rated for industrial environments with conductive pollution or dry non-conductive pollution that becomes conductive through condensation — standard for unsealed control cabinets.","metaTitle":"Siemens 3RW5236-2TC04 SIRIUS Soft Starter, 200-480 V","metaDescription":"Siemens 3RW5236-2TC04 SIRIUS soft starter, rated 200-480 V with 81 A minimum current.
