Eaton DS7-340SX041N0-N, Eaton DS7 soft start controller, Frames 3 and 4, 41 A, 30 hp, 480 V, 24 Vac/Vdc, Internal bypass, IP20, HFD3150L circuit breaker, 150 A class RK5 max fuse, Generation 7 series. The Eaton DS7 easily fits in place of existing soft starters, wye-delta starters or across-the-line NEMA and IEC starters. The voltage ramp start method provides a voltage ramp to the motor for constant torque increase. Users set initial voltage values and the duration of the ramp to full voltage conditions. Soft Stop allows for a controlled stopping of load when a stop-time greater than the coast-to-stop time is desired; for high friction loads where a sudden stop may cause system damage.

Core features
● Run bypass mode greatly reduces internal heating created by the power dissipation across the SCRs.
● Bypass contactor directly connects the motor to the line and improves system efficiency by reducing internal power losses.
● Less heat minimizes enclosure size and cooling requirements, and maximizes the life of all devices in the enclosure.
● LED displays device status and provides fault indication.
● Variable ramp times and voltage control (torque control) settings provide unlimited starting configurations for maximum application flexibility.
● Manages peak starting torque to diminish mechanical system wear and damage.
● 120 Vac or 24 Vdc control voltage available.
● Temperature monitoring sensors allow starter to trip in over/under temperature conditions, preventing device failure.
● Available with or without SmartWire-DT capability.
