− The softstarter has to be placed outside the Ex area, either in another location or inside an ATEX approved panel. − A separate ATEX approved overload relay from ABB must be used together with a line contactor. This overload relay will replace the built-in EOL in the softstarter and has an ATEX approved tripping curve.

The softstarter shall be designed for three-phase control with two anti- parallel SCRs in each phase. The softstarters shall be designed to the following specifications: A) Power Ratings 1) Input: 200-690V +/-10%, 3-Phase 50/60 Hz. Softstarters shall be phase sequence insensitive.
reducing torque. Some soft starters may use solid-state devices to help control the flow of the current. They can control one to three phases, with three-phase control usually producing better results. Figure 1. Soft Starter Schematic Most soft starters use a series of thyristors or silicon controlled rectifiers (SCRs) to reduce the voltage.
Starts, stops and protects. Emotron TSA softstarters take motor control to a new level. Soft torque starting, intelligent load monitoring and smart stops are all included and accompanied by a robust and compact design. The …

VSDs are less efficient than soft starters, so cost more to run (3% versus 0.5% losses). VSDs only save energy if they reduce losses in the driven load by operating part of the time at reduced speed. At constant full speed operation, they are less efficient. The only other reason to use a VSD over a soft starter, is to reduce the start current ...
The Emotron TSA softstarter has a built-in load monitor that protects your machine and process against costly downtime, equipment damage and break-down. It reacts immediately if a crusher is jammed, a pump is running dry, a compressor is idling, or a fan is operating inefficiently due to a blocked filter. This is achieved by constant viewing of ...
The PST(B) softstarter is the most advanced softstarter in the range with almost all imaginable functionality included. All the advanced protections for the motor, the softstarter and the load ensure a trouble free operation. Pre-warnings even allow problems to be detected before the motor needs to be stopped
A fully solid-state softstarter is designed to run an application, at full voltage and at speed, without the need or use of a bypass contactor after the start mode. The SCRs are fully rated at the amperage specifications of the softstarter including its AC-53a utilization rating. Figure 2 - Solid-State Softstarter Wiring 1/L1 3/L2 5/L3 2/T1 4 ...
You can use slow speed with the soft starter for applications that require basic controlled-position starting and stopping. Figure 3 shows how the soft starter could start at slow speed, then transition to full speed, and then brake to slow speed. Slow speed can then be held until a stop command is provided.
A soft starter ensures smooth and uniform starting by torque control for gradual acceleration of the drive system which goes on to help in preventing jerks (in the case of phase 3 control starters). This …

They cannot accommodate varying load conditions (eg. loaded or unloaded starts). They do not provide soft stop. The main advantages of star/delta starters are: They may be cheaper than a soft starter. When used to start an extremely light load, they may limit the start current to a lower level than a soft starter.
