Product description

The Schneider Electric LC3D12AP7 is a TeSys D series star-delta starter designed for controlling three-phase motors. It features three poles, a 12A AC-3 rating, and 11kW power capacity at 400V. This starter operates with a 230V AC coil and includes one normally closed (NC) auxiliary contact. Its plate-mounted design and IP20 rating make it suitable for industrial environments.

This star-delta starter is commonly used in applications requiring reduced starting current and torque, such as large motor systems, pumps, compressors, and fans. It helps to minimize inrush current, reducing stress on the power supply and motor during startup, thereby extending the lifespan of the equipment.

Stanlo Automation offers the Schneider Electric LC3D12AP7, a reliable component for your motor control needs. As a veteran-owned surplus parts distributor, we are dedicated to providing quality products and prompt service to keep your operations running smoothly.

Frequently asked questions

What is the purpose of a star-delta starter like the LC3D12AP7?

A star-delta starter, such as the Schneider Electric LC3D12AP7, is used to reduce the starting current and torque of three-phase motors. It achieves this by initially connecting the motor windings in a star configuration for starting and then switching to a delta configuration for running, which is essential for large motors to prevent power system overloads.
