1. Core Overview

2. Key Technical Parameters

3. Core Product Features

• Inrush Current Suppression: During start-up, the motor starting current can be controlled within 1.5-3 times the rated current, preventing impact on the power grid and mechanical structure.
• Overload and Phase Failure Protection: Built-in multiple protection functions such as overload, overcurrent, overvoltage, undervoltage, phase failure, and phase failure start-up to ensure safe operation of the motor.
• Low Energy Consumption: Unlike frequency converters, soft starters do not consume additional power in normal operation and have extremely high efficiency.
• Compact Structure: Adopting modular design, it is small in size and light in weight, easy to install and maintain.

4. Structure and Composition

• Main Circuit: Including main contact group, three-phase motor starting circuit and overload protection components (fuse or thermal relay).
• Control Circuit: Responsible for signal reception and processing, and executing external control commands (such as on, stop, commutation).
• Interface Board: Used to connect external control signals (such as PLC signals, on-site button signals) and motor feedback signals.
• Shell: Usually metal or plastic shell with protection level, dust-proof and waterproof.

5. Typical Application Fields

• Water Pump System: Prevents water pump bearings from being damaged by impact during start-up.
• Compressor: Protects the compressor from current impact during high-load start-up.
• Fans and Conveyors: Smooth start-up to prevent transmission chains or belts from breaking due to impact.
• Other Low-Voltage Motor Drives: Such as concrete mixers, elevators, etc.

6. Installation and Maintenance Points

Installation Recommendations

• Wiring: Connect according to the standard wiring diagram of the ATS48 series to ensure that the motor leads correspond to the phase sequence of the soft starter.
• Heat Dissipation: Although the power consumption of ATS48D62Y is low, it still needs to be installed in a well-ventilated environment to avoid overheating.
• Position: Install on a horizontal surface, avoiding direct placement in a humid or corrosive environment.

Maintenance

• Regular Inspection: Check the tightness of terminal bolts every six months to ensure no looseness.
• Component Replacement: After the soft starter stops service, if it needs to be used continuously, replace the aging-prone components such as the internal overload relay to ensure its working reliability.
• Software Update: If the equipment is still under warranty, regularly check whether Schneider official has released firmware updates to solve potential compatibility issues.
