Minimum load is 15 % relative to the smallest settable Ie. Rated voltage spans 200 to 480 V. Trip class defaults to CLASS 10A per IEC 60947-4-2, with selectable 10E and 20E curves. For a standard pump or fan load, 10A is adequate; for high-inertia starts (centrifuge, crusher), 20E buys the extra thermal budget. The soft starter's own thermal model tracks the motor heating curve, so the trip class selection governs the protection coordination with upstream motor circuit protectors. ## Mounting and clearances — screw-fixed, not DIN-rail Fastening method is screw fixing, not snap-on DIN rail. The mounting surface must be vertical; the unit is rotatable ±90° and tiltable ±22.5° to the front and back. Clearance requirements: 100 mm upwards, 10 mm forwards, 0 mm backwards, 75 mm downwards, 5 mm at the side. The 0 mm backwards clearance means the backplane can sit flush against the panel gland plate — useful when depth is tight. Overall dimensions: 306 mm height, 185 mm width, 203 mm depth. ## Lifecycle and compliance — current production, CE/UL/CSA Lifecycle stage is current. Approvals include CE marking, UL approval, and CSA approval. Pollution degree 3 per IEC 60947-4-2.","metaTitle":"Siemens 3RW5227-3TC04 SIRIUS Soft Starter, 40.5 A Min","metaDescription":"Siemens 3RW5227-3TC04 SIRIUS soft starter, minimum 40.5 A, rated 200-480 V.
