SOFTSTARTERS SOFTSTARTERS APPLICATIONS

Fans PROTECTION DEVICES
Common questions:
How to avoid extended voltage drops due to long starting time?
Use an ABB softstarter equipped with current limit to keep control of the starting
current.
How to extend the life of the driving belts? Circuit Protection Devices and Control
Our softstarters will reduce the mechanical stress during start, thus avoiding slipping
Circuit Protection De
belts.
How to ensure the operation of the fan?
A softstarter with underload protection will detect broker belts, making the operator
immediately aware of the problem.
Compressors
Common questions:
How to ensure a long life of the compressor?
Using a softstarter for starting will reduce the accelerating torque, thereby minimizing
the mechanical stress.
How to build a compact compressor unit?
PROTECTION DEVICESvices and Control
Using a compact softstarter like PSR or PSE will allow a much more compact starting
equipment than for instance a star delta starter.

Conveyor belts
Common questions:
How to reduce the need for service and repair of the conveyor belt?
A softstarter from ABB will cause minimal mechanical stress on the conveyor belt.
How to avoid that the conveyor belt is running in the wrong direction?
Use a softstarter with phase reversal protection.
How to improve the efficiency of the conveyor belt?
Using softstarters with high and low current warnings allows you to load on and off the
conveyor belt-How to ensure a successful start in high inertia loads?
A softstarter with kick start function will provide sufficient torque to be able to
overcome the initial high friction from a temporarily jammed belt.
