Common Questions Answered

• What is the main benefit of using this soft starter?

It greatly reduces the inrush current when starting a motor. This prevents network voltage drops and protects mechanical parts from sudden jolts.

• Can I use this starter for a 480V, 200HP motor?

Yes. The PST300-600-70 is rated for 300A at 500V, which is suitable for a 200HP (approx. 150kW) motor. Always check your motor’s full-load current first.

• What does ‘Inside Delta Connection’ mean?

It is a wiring method where the starter is placed inside the motor’s delta winding. This allows the starter to handle higher motor currents (515A) at a lower cost.

• How do I reset a fault indicated by the red LED?

First, identify and resolve the cause (e.g., overload, phase loss). Then, you can usually reset it by cycling the control power or using a remote signal.

• Is professional installation required?

We recommend installation by a qualified electrician. Proper sizing, wiring, and parameter setting are crucial for safe and reliable operation.
