In-Line Soft Starters: Direct Power-to-Motor Protection

In-line soft starters provide reliable AC motor control by installing directly between power and motor, eliminating the need for bypass contactors. These units deliver continuous protection from startup through operation to shutdown, gradually applying voltage to:

✓ Reduce starting currents by up to 60%
✓ Prevent mechanical stress on belts and gears
✓ Extend motor lifespan 2-3X

Space-saving and economical, our in-line starters are ideal for:

• Panel space savings - 30% smaller than bypass starters
• High cycling capacity - Rated for 50+ starts/hour
• Cost efficiency - No bypass contactor required
• Wide voltage range - 220V/380V/440V options
• Thermal management - Natural cooling (≤55kW) / Forced air (>55kW)
• Easy retrofitting - Compatible with existing motor controls
