## Overview

The SSR-100WA-R1 is a robust 4kW single-phase motor soft starter module designed for 220-240V motors. It reduces inrush current up to 50A, adjustable over a 0-30 second soft start period, ensuring smooth motor ramp-up and extended equipment life. Compatible with a wide range of industrial applications including pumps, fans, and conveyors, it replaces traditional bulky starters with a compact, efficient solution favored by professionals seeking reliability and control.

## Description

This product is commonly used for motors with the following voltages:220V.(50Hz,60Hz).230V.(50Hz,60Hz).240V.(50Hz,60Hz).The above three voltages are universal for this product.Single-phase 220V soft start module use range:Petroleum,chemical,fire,construction,metallurgy,building materials,mining,environmental protection and other fields.Fans,pumps,belt conveyors,ball mills,car washing machines,conveyors and compressors.It is an ideal replacement for traditional star/delta conversion,auto-coupling buck,magnetic control buck,inverter and other step-down starting devices.220V single-phase motor soft start module(motor conversion method)model:SSR-20WA-R1(1kw)SSR-40WA-R1(1.5kw)SSR-60WA-R1(2kw)SSR-100WA-R1(4kw)SSR-150WA-R1(6kw)SSR-200WA-R1(8kw)According to the actual working current 5 times:power÷voltage×5in case:Your motor is 8000w power÷220v voltage ×5=(181.81WA should choose 200WA)should choose the parameter closest to that model.our soft start is universal for the motor,regardless of whether the motor has a capacitor or not.If your motor is working for a long time,the motor above 2000W needs to be equipped with a heat sink.Single phase motor compared to starter moduleVoltage compatibility:(220V+0V=single-phase 220V,AC)(230V+0V=single-phase 230V,AC)(240V+0V=single-phase 240V,AC)(220V+220V=two-phase 380V-400V,AC)Frequency:50Hz,60HzSoft start time is adjustable between 0-30 seconds (soft start time refers to the entire process 0-220V,0-380V)Slowly adjust the starting voltage from 0-50?Reaching the rated voltage (220-380V)There are two ways to use it:1.After closing the switch,the main power will be energized and start soft start.2.Use the switch to control,close the soft start to start,open to stop.The soft start module has 2 programs:1.SSR-40WA-R1 has soft start and no soft stop.2.SSR-40WA-R2 h

Review: Handles a large inrush current from a loaded 5hp induction motor - I am using this with a 5hp farm duty motor on a heavy start load machine and it does exactly what it should do, handling the inrush current like a champ. It might be overkill for my use but it is always better to go larger than you need. I am using a heatsink and fan and I built a control circuit to switch the load once it is up to full speed so that it doesn't have to carry the load once running.
Review: Five stars, but with a few quibbles - I installed this on my water well and now it can start when running on solar battery backup. Inrush amps went from about 70 to 30. I could have adjusted it lower, but have read that water well pumps can fail prematurely if they don't come up to speed quickly. I get pressure in about a second. For longevity concerns, I only plan on using this during power outages so I will install a bypass switch. The seller says I can use jumpers across the input and output terminals and it won't harm the device. That's much simpler than using a 4 pole switch to isolate it. I bought the 4Kw version. My well draws 12 amps steady state and the soft start gets warm so I will add a heat sink. That's where my first quibble comes in. It will be difficult to mount this inside an enclosure and also have a heat sink because of the way the mounting holes are arranged. I may try to find an aluminum enclosure that will provide heat sinking and also make it easy to add a heat sink on the outside. The other quibble is the adjustments. As others have said, there is no manual. I learned that the time adjustment has more effect on the inrush than %. BTW, increasing the time reduces the inrush and surprisingly, increasing the % increases the inrush. I have mine set to 2.5 seconds and 50%. Other than that it worked great in initial testing. Time will tell how robust it is.

### ⭐⭐⭐⭐ It works!
*by P***S on May 18, 2024*

It’s a basic softstarter which works. It comes without any instructions… Didn’t check online if I could find something.
