Lovato 51ADX0470 severe-duty three-phase soft starter rated at 470 A for 208–415 V AC asynchronous motors, with adjustable current limitation, motor protection and provision for an external bypass contactor.
£12,699.30
The Lovato 51ADX0470 is an advanced three-phase soft starter designed for controlled starting and stopping of asynchronous three-phase motors in severe-duty industrial applications. As part of the Lovato Electric ADX soft starter series, it is designed for severe-duty starting at up to 5 × Ie and is predisposed for connection to an external bypass contactor.
The 51ADX0470 provides three-phase control with torque or voltage ramp starting and adjustable current limitation. It also supports torque-ramp, voltage-ramp and free-wheel stopping, together with motor overload electronic protection, torque control, kick start, dynamic braking, PTC motor protection and comprehensive supply, motor and starter protection functions.
With a rated starter current of 470 A and a three-phase 208–415 V AC supply, the 51ADX0470 supports IEC motor ratings of 132 kW at 230 V AC, 250 kW at 400 V AC and 315 kW at 500 V AC. Its forced cooling system and provision for an external bypass contactor make it suitable for demanding high-power industrial motor-starting applications.
Soft starters progressively control the electrical power supplied to a motor during acceleration, helping to reduce the high starting current and mechanical stress associated with direct-on-line starting. The Lovato 51ADX0470 provides three-phase control with configurable torque or voltage ramp starting, allowing acceleration to be matched to the requirements of the motor and driven equipment.
The 51ADX0470 is predisposed for connection to an external bypass contactor rather than incorporating an internal bypass. Its protection functions include motor overload protection, locked-rotor detection, current asymmetry monitoring, minimum-torque protection, phase-loss and phase-sequence protection, overcurrent protection and thyristor overtemperature protection.
