Description
The Benshaw RB2-1-S-477A-17C is an open chassis reduced voltage soft starter from the RB2 series, rated up to 477 A and suitable for three phase motors on 240 to 575 VAC supplies. It uses Benshaw MX2 control technology and includes a run duty integral bypass contactor, which closes once the motor is at speed to carry the running current and reduce heat dissipation.
RB2 soft starters are used to limit inrush current and mechanical shock when starting pumps, fans, compressors, conveyors, and similar three phase motor loads. The open chassis construction is intended for mounting inside a customer supplied enclosure or control panel.
