The integrated thermistor motor protection circuit monitors winding temperature directly — no external relay needed. Front touch protection meets IP20 per IEC 60529, finger-safe for vertical contact. Pollution degree 3 per IEC 60947-4-2 means it tolerates conductive dust in standard industrial enclosures without conformal coating. ## Environmental and integration limits Rated insulation voltage is 600 V — this sets the clearance and creepage design for the panel buswork. The storage, operation, and transport classes per IEC 60721 define the allowable envelope: occasional condensation during storage (class 1K6), no salt mist in operation (3C3), and a maximum fall height of 0.3 m during transport (2M2).","metaTitle":"Siemens 3RW4026-1TB04-ZW97 SIRIUS Soft Starter, 25 A, 11 kW","metaDescription":"Siemens 3RW4026-1TB04-ZW97 SIRIUS soft starter, 25 A, 11 kW at 400 V, 200-480 V AC, 24 V AC/DC control.
