1. Overview

2. Performance Features

◆ Compact Size, Full Functionality

This cabinet integrates a high voltage solid state soft starter, a high voltage switchgear, and a bypass cabinet into one, reducing the footprint by half compared to separate high voltage switchgear and soft starter cabinets, while offering soft start, soft stop, switchgear, and bypass functionalities.

◆ Low Start Current, Significant Energy Saving

The TGRY Series Medium and High Voltage Switchgear Solid State Soft Starter Integrated Cabinet controls voltage by changing the conduction angle of the thyristor, resulting in no energy loss, a low start current that is 2.5 to 3.5 times the rated current.

◆ Strong Anti-Interference, Suitable for Various Environments

The cabinet is designed with a special RC absorption circuit for strong anti-interference. The product performs reliably, unaffected by the environmental temperature or geographic location, enabling frequent starts.

◆ Comprehensive Protection Features, High Safety

Feature overload, phase loss, and startup peak overcurrent protection functions. Startup parameters are selectable, adjustable, and controllable.

◆ Maintenance-Free, Cost-Saving

Use a maintenance-free design, reducing the wiring cables for high voltage switchgear and soft starter cabinets. No other maintenance required after deployment, significantly saving on maintenance costs.
