Solutions that Match Requirements
ISA D - Heavy Duty Soft Starter
Reliable Soft Starting for Demanding Industrial and Marine Applications
The ISA D is a heavy-duty low-voltage soft starter designed for three-phase induction motors in industrial and marine applications. It provides precise motor control while reducing starting current, mechanical stress, and torque shocks. As a result, operators can improve equipment reliability and extend motor life.
In addition, the ISA D supports both line and inside-delta connections. This flexibility allows users to optimize installation costs while meeting application requirements.
Advanced Motor Control and Motor Protection
The ISA D combines advanced soft starting and stopping functions with a comprehensive motor protection package. Consequently, it helps protect motors during every stage of operation.
Furthermore, features such as pump control, slow-speed operation, electronic reversing, and motor insulation testing improve process performance and reduce maintenance requirements. Operators can therefore identify potential issues early and prevent unplanned downtime.
Built for Critical Applications
The ISA D performs reliably in harsh industrial and marine environments. It supports critical applications including pumps, compressors, conveyors, thrusters, and propulsion systems.
Moreover, its robust design withstands demanding operating conditions. At the same time, flexible communication options simplify integration into modern control and automation systems. Thanks to its intuitive user interface, commissioning is fast and straightforward.
