Soft Starter · 32A 200-480 VAC 3-Phase 20 HP 480 V Internal Bypass · 23 s Ramp · Eaton DS7-342SX032N0-N
Eaton DS7 series soft starter for 3-phase motors with a 32 A rating, 200-480 VAC line voltage, and 110-230 VAC control supply. Rated up to 20 HP at 480 V, it is commonly used to reduce inrush current and mechanical stress on pumps, fans, and conveyors during motor starting.
What this product is for
This soft starter is used to start 3-phase AC motors more smoothly than across-the-line starting. It helps limit starting current and reduce mechanical shock on connected equipment in industrial and commercial motor control panels.
Use for
Use for pumps, fans, conveyors, compressors, and similar fixed-speed motor loads where reduced starting stress is required. Suitable where the application fits a 32 A soft starter with line voltage from 200 to 480 VAC and control voltage from 110 to 230 VAC.
Avoid for
Avoid for applications that need variable speed control, high starting torque tuning, or frequent starts beyond the device duty rating. Also avoid using it as a substitute for a VFD where process speed control is required.
Best for
Best for electricians and panel builders specifying a compact soft starter for standard-duty 3-phase motor starting. It is a practical choice where reduced inrush current, smoother acceleration, and simpler installation matter more than speed control features.
Installed in
Typically installed in motor control panels, OEM equipment, process skids, pump panels, and light industrial machinery. Product dimensions are approximately 7 in x 5.5 in x 2.5 in (178 x 140 x 64 mm).
Why this product exists
This product exists to reduce electrical and mechanical stress during motor starting. Compared with direct-on-line starting, a soft starter can help lower line disturbance and reduce wear on belts, couplings, and driven equipment. Actual performance depends on motor characteristics, load type, wiring method, and local electrical code.
Compared with similar products
Compared with a contactor-only starter, this soft starter provides controlled ramp starting. Compared with a VFD, it is typically a simpler choice when the motor only needs smooth starting and stopping rather than continuous speed control. This model is rated 32 A and up to 20 HP at 480 V, with a 23 second ramp specification and 300% current limit at 40 deg C.
