FAQs
1. What is an FASD starter?
Ans: An FASD (Fully Automatic Star Delta) starter begins motor operation in star mode & automatically switches to delta mode to reduce starting current.
2. What does 90–150A mean?
Ans: It indicates the high current range suitable for very large motors & heavy-duty applications.
3. Why use a star-delta starter instead of DOL?
Ans: A star-delta starter reduces starting current & mechanical stress, improving motor lifespan & system efficiency.
4. What is the role of the timer?
Ans: The timer controls the automatic transition from star to delta during motor startup.
5. Is this suitable for heavy industrial applications?
Ans: Yes, it is specifically designed for large motors used in industrial machinery & high-load operations.
6. What voltage does it support?
Ans: It operates at 415V AC, which is standard for three phase industrial systems.

Warranty
- All products listed in the price list are covered by a warranty against manufacturing defects for a period of 18* months from the date of purchase.
- For Lauritz Knudsen MCBs & Isolators mounted inside Lauritz Knudsen Distribution Boards, an extended warranty of 5 years is provided.
- In the event of a defect due to faulty workmanship or other associated reasons, the manufacturer will, at its discretion, remedy the defect or replace the faulty parts or the entire product as soon as possible, free of cost.
- This warranty is subject to proper usage and efficient maintenance and does not cover defects arising from fire, accidents, inefficient maintenance, faulty operation, or deliberate or accidental damage.
- The warranty does not cover damage to power electronic components such as thyristors & IGBTs, which primarily fail due to over-temperature or over-voltage. Users must take adequate precautions to eliminate such conditions.
- The manufacturer shall not be responsible or liable for any special, incidental, social, or consequential losses (including loss of profits), punitive damages, injury, or damages of any kind solely attributable to defect or failure of its products.
- The manufacturer shall not be liable in any manner for issues related to or failure in the performance of any other equipment to which the product is connected.
