Introducing Safesav Soft Starters
Smooth motor starts. Less stress on gear. Better uptime.
⚙ What is a soft starter?
A soft starter controls inrush current and torque during motor start and stop,
protecting mechanical systems and extending equipment life. The
Safesav SSR series uses intelligent digital control to ramp motors up and down,
avoiding the shock loads you see with DOL or star-delta starts.
🔧 Why choose Safesav SSR soft starters
- Smooth acceleration and deceleration with selectable ramp profiles.
- Integrated protections: overload, over/under-voltage, phase loss, stall, overheat.
- Compact form factor for easy retrofits in existing panels.
- Clear status indication and parameter setup.
- Models from small machines up to 75 kW typical at 400 V.

➡ Quick part number guide (SSR series)
The SSR code tells you voltage, current rating, control supply, and control topology:
- SSR40 = 400 V main voltage class.
- Current example
4T5 = 4.5 A (T denotes the decimal).
- A = 110 to 240 V AC control. B = 24 V DC control.
- 3P3 = three-phase control (typical). 1P1 = single-phase control variant.
These conventions align with the SSR series data published by Safesav and our own product pages. :contentReference[oaicite:1]{index=1}

🛠 Typical applications
- Pumps and fans where reduced hydraulic or airflow shock is critical.
- Conveyors and material handling to prevent mechanical jerk.
- Compressors and mixers to minimise belt and coupling wear.
- General machinery where DOL starting causes nuisance trips.
