Type S701 Soft Start Controller
with Auxiliary Contact
S701C25N3BP Solid State Soft Start Controller
Product Description

The S701 device is a reduced voltage soft start controller designed to control acceleration and deceleration of three-phase motors. With the auxiliary contact, it is possible to control an external bypass to reduce heating and increase acceleration and deceleration times.

 

The unit provides the user with the ability to adjust initial torque, ramp up and down time and also select kick start for high inertia loads.
