Frequency Inverter Panel vs Soft Starter Cabinet

This guide compares two common motor-control cabinet approaches: a frequency inverter panel built around a variable frequency drive and a soft starter cabinet built around a soft starter. It maps each approach to Boray catalog products by name.

Frequency Inverter Panel Basis

A frequency inverter panel is built around a frequency-control device. In the Boray catalog, the BR100 Variable Frequency Drive is the named product for that panel type.

Soft Starter Cabinet Basis

A soft starter cabinet is built around a soft-start device. In the Boray catalog, the ST300 Online Soft Starter Cabinet is the named cabinet-type product for that panel type.

Catalog Device Families Compared

The comparison is between the variable-frequency-drive family and the soft-starter family. The BR100 Variable Frequency Drive belongs to the frequency inverter side, while the ST300 Online Soft Starter Cabinet and GE300 Online Soft Starter Without Bypass belong to the soft starter side.

Which Cabinet Name Matches the Control Need

When the control need is a frequency inverter panel, the catalog match is the BR100 Variable Frequency Drive. When the control need is a soft starter cabinet, the catalog matches are the ST300 Online Soft Starter Cabinet or the GE300 Online Soft Starter Without Bypass.

Boray Product Mapping

Use these catalog names to distinguish the two approaches: BR100 Variable Frequency Drive for frequency inverter panel; ST300 Online Soft Starter Cabinet for soft starter cabinet; GE300 Online Soft Starter Without Bypass for online soft starter without bypass.
