Emotron TSA Soft Starters
The Emotron TSA provides controlled starting and stopping for three-phase motors in pumps, fans, compressors and conveyors. It helps reduce starting current and mechanical stress in applications that run at a fixed speed.
Control and protection for your process
- Three-phase torque control: controls motor torque during starting for smooth acceleration.
- Internal Bypass: Internal Bypass contactors bridge the SCRs once the motor is at full speed to reduce losses in the SCRs.
- Controlled pump stops: torque-controlled stopping helps reduce water hammer.
- Load monitoring: detects shaft power overload and underload conditions to help protect the driven equipment.
- Motor protection: built-in electronic motor overload protection and a thermistor input support motor temperature monitoring.
- Easy setup: a multilingual control panel supports parameter copying between units.
Selecting a TSA soft starter
The TSA range covers rated currents from 16 to 960 A, with three-phase supply versions for 200–525 V and 200–690 V. Units have IP20 protection for installation in a suitable enclosure. Communications and additional I/O are available as options.
To help select the right model for your starting duty, provide:
- The supply voltage, motor nameplate current and motor power.
- The application, starting load, required starting time and number of starts per hour.
- The stopping requirements, including any need for controlled pump stopping.
- The ambient temperature, installation altitude, enclosure and available mounting space.
- The control supply, motor temperature sensors, control signals and network connections required.
TSA soft starter documentation
For an existing installation, record the full soft starter type code and software version. Use the matching TSA instruction manual when checking parameters, terminals or option compatibility.

Frequently asked questions
What applications suit a TSA?
The TSA suits applications such as pumps, fans, compressors and conveyors that need controlled motor starting and stopping. Selection depends on the motor current, load and starting duty.
Does a TSA provide variable speed control?
A TSA soft starter controls motor starting and stopping; it does not provide continuous variable speed control during normal operation. If your process needs speed adjustment to match flow or pressure demand, consider an Emotron FDU variable frequency drive.
Is the TSA available in New Zealand?
The Emotron TSA soft starter is available in New Zealand ex stock from Advanced Motor Control Ltd subject to prior sale.
Can the TSA be serviced and/or repaired in New Zealand?
A TSA soft starter can be repaired in New Zealand by Advanced Motor Control Ltd, but may need to be returned to Christchurch of repair.
Spares are carried in stock in Christchurch.
What information is needed for a replacement?
Send a photo of the existing soft starter label, the motor nameplate details and a description of the application, starting duty and control connections. This helps identify a suitable replacement.
