High-power motors (125HP and above) are critical for industrial tasks like driving large compressors or conveyors. Direct startup of these motors often causes stress and damage. The SHUYI 125 hp soft starter solves this by regulating voltage and current, ensuring gentle and safe motor activation.

1. Core Application Scenarios
The SHUYI 125 hp soft starter fits perfectly in manufacturing plants. It powers 125HP air compressors, preventing sudden pressure spikes in air systems. This keeps production lines running without disruptions.
It also works well in mining operations. It controls 125HP conveyor belt motors, handling the heavy load of ore transport. Its stable performance avoids belt slippage or motor overheating.
In large HVAC systems, it drives 125HP ventilation fans. It adjusts fan speed gradually, reducing noise and ensuring consistent airflow in factories or warehouses.
2. Key Protection Features
This soft starter limits inrush current to 3x the motor’s rated value. Direct startup usually causes 6-8x surges, which damage motor windings. The SHUYI model avoids this risk.
It has built-in overload protection. If the motor’s load exceeds 125HP capacity, the soft starter cuts power temporarily. This prevents motor burnout and costly repairs.
It also offers phase-loss protection. Missing phases are common in industrial grids. The soft starter detects this issue and shuts down, shielding the motor from uneven current damage.
3. Energy Savings & Cost Benefits
The SHUYI 125 hp soft starter reduces startup energy use by 15-20%. Traditional direct startup wastes electricity on sudden current surges. This cuts monthly energy bills for businesses.
It extends motor lifespan by 30% on average. Less stress from smooth startup means fewer motor replacements. This lowers long-term equipment costs.
It also reduces maintenance frequency. Stable operation means fewer breakdowns. Technicians spend less time on repairs, saving labor costs.
4. Durable Design Details
The soft starter uses a rugged metal enclosure. It has an IP20 rating, blocking dust and light moisture. This makes it suitable for dusty industrial environments.
It includes a high-efficiency heat sink. Long hours of 125HP motor operation generate heat. The heat sink keeps internal components cool, ensuring consistent performance.
It uses high-quality electrical components. These parts resist wear from frequent use, ensuring the soft starter works reliably for 8+ years.
5. Easy Installation & Operation
The SHUYI 125 hp soft starter fits standard 200mm-deep control cabinets. No custom modifications are needed, saving installation time.
It has color-coded wiring terminals. Technicians can connect wires quickly without confusion. Most installations are completed in under 2 hours.
It has a simple keypad interface. Operators can set startup time (1-60 seconds) with just a few presses. No advanced training is required for daily use.
