SST-EST series built-in bypass motor soft starter - intelligent start, efficient escort

In order to meet the higher requirements of the industrial field for motor starting performance and equipment protection, the SST-EST series built-in bypass motor soft starter came into being. This product integrates intelligent control, high reliability and flexible installation, and is designed to provide smooth start and stable operation guarantee for three-phase asynchronous motors, effectively reducing mechanical shock and power loss. It is an ideal choice for improving the life and energy efficiency of production equipment.

Core parameters and performance advantages

Wide voltage compatibility, strong adaptability

Supports 230Vac, 400Vac±15% dual voltage levels, compatible with 50Hz/60Hz power grid standards,

Multi-specification current coverage, flexible matching needs

Provides 9 rated current models from 2.2A to 45A, suitable for small and medium-sized three-phase asynchronous motor loads, and meets the starting requirements of various application scenarios such as fans, water pumps, conveying equipment, compressors, etc.

Intelligent start-stop control, extending equipment life

Built-in bypass design, automatically switches to bypass operation after the motor starts, reducing the power consumption of the soft starter itself;

Start frequency limit <10 times/hour, scientifically control the start-stop interval, avoid overheating of devices caused by frequent operation, and ensure long-term stable operation of the equipment.

Compact design, easy installation

Protection level IP20: effectively prevents the intrusion of solid foreign matter, suitable for dry and clean electrical cabinet environment;

Natural cooling

Dual installation mode: supports wall-mounted fixing or standard rail installation (such as DIN rail), adapting to different cabinet space requirements.

Core value of the product

Energy saving and consumption reduction: reduce instantaneous current impact through smooth start, reduce grid load and energy waste.

Precise protection: built-in multiple protection functions (such as overload, phase loss, overvoltage, etc.), real-time monitoring of motor operation status, and prevention of faults.

Simplified operation and maintenance: modular structure design, easy maintenance; bypass operation mode reduces device loss and reduces life cycle cost.

Typical application scenarios

Manufacturing: smooth start control of motors such as machine tools, conveyor belts, and packaging equipment.

Public utilities: Energy-saving start-stop management of central air-conditioning compressors, water pumps, and fans.

Mining and construction: Mechanical shock relief for heavy-load equipment such as crushers and mixers.
