Upgrade your motor protection with this 3 Phase Motor Starter online slow start module featuring solid state relay control. Designed for smooth ramp-up, it helps reduce inrush current, prevent breaker trips, and minimize mechanical shock in pumps, fans, and compressors. With decompression and step-down controller functions and support up to 5 kW, it’s an ideal choice for Pakistan industries needing stable three-phase motor starting and low-maintenance performance.
3 Phase Motor Starter Module for Industrial Motor Control
If you need smoother motor startup and better protection for machinery, a 3 Phase Motor Starter is one of the most practical upgrades for industrial and commercial setups in Pakistan. This online slow start module is designed to reduce inrush current during startup, helping prevent sudden voltage dips, motor stress, and mechanical shock on couplings, belts, pumps, and compressors. It’s especially useful where unstable line conditions or frequent starts can cause overheating, breaker trips, or premature motor failure.
This solid state solution is widely searched as a “3 phase motor controller Pakistan” option because it improves reliability without complex VFD programming. With decompression and step-down control, it supports smoother load handling in applications such as air compressors, water pumps, HVAC blowers, workshop machinery, and small industrial production lines.
Online Slow Start Module with Solid State Relay Technology
Unlike traditional star-delta starters that switch abruptly, this online slow start module uses solid state relay (SSR) control to ramp the motor smoothly. This controlled ramp-up reduces torque shock and helps protect mechanical parts from wear. Many buyers in Pakistan prefer SSR-based starters because they require less maintenance than contactor-heavy systems and work well in dusty electrical rooms and factory environments.
If you’re searching for “soft starter for compressor” or “pump soft start controller,” this module is built to deliver stable starting performance, reduced noise, and lower startup stress—especially in systems where load spikes happen instantly at start.
Decompression and Step-Down Controller for Load Protection (Up to 5KW)
The decompression feature is ideal for compressor-type loads where pressure needs to release before a stable restart. Meanwhile, step-down control helps manage the starting profile so your motor doesn’t pull excessive current the moment it starts. Rated for up to 5 kW5 \text{ kW}5 kW, this controller is a practical fit for many common three-phase motor setups used in Pakistan’s workshops, small factories, and building services.
This unit is often used as a 5 kW motor starter alternative for smoother starts and fewer trips. It also helps extend motor life without switching to a full variable frequency drive.

FAQ: 3 Phase Motor Starter
Q1: What does a 3 phase motor starter do?
A 3 phase motor soft starter reduces starting current and ramps up voltage gradually, minimizing stress on motors and mechanical parts.
Q2: Is this online slow start module better than star-delta?
For many loads, yes. Star-delta starts in steps, while an SSR-based soft starter offers smoother ramping and reduced torque shock.
Q3: Can I use this 5kW motor starter for pumps and compressors?
Yes, it’s commonly used for pumps, fans, and compressors. Decompression support is especially helpful for compressor applications.
Q4: Does it replace a VFD?
Not fully. A VFD controls speed during operation, while a soft starter mainly controls starting (and sometimes soft stop). If you only need smooth start and protection, a soft starter is a cost-effective choice.
