TeSys Tera System

Overview

The TeSys Tera Motor Management System (or TeSys Tera system) is part of the TeSys™ Active range of intelligent relays and motor starters. The TeSys Tera system is designed as a reliable building block for Intelligent Motor Control Centres (iMCCs) to provide complete protection, control, and monitoring capabilities for single-phase or three-phase AC induction motors.

The TeSys Tera system is installed in the low voltage switchgear system and connects the higher level automation system via fieldbus network and the motor feeder.

TeSys Tera system:

Covers conventional and advanced motor protection, metering, and monitoring in iMCC feeders into single, easy to configure, compact communicating module with a display.
Provides protection controller for low voltage contactor-controlled motor starter feeders.
Provides flexible and modular motor management system for motors with constant speeds in low voltage applications.

NOTE: Please contact your local Schneider Electric representative concerning the availability of the EtherNet/IP variant.

Functional Characteristics

The TeSys Tera system manages:

Single-phase or three-phase AC induction motors up to 100 A with integral sensor module.
Single-phase or three-phase AC induction motors up to 810 A when using external current transformers.
The connection between the control system and the motor feeder, increases plant availability.
Significant savings to the installation, commissioning, operation, and maintenance.
Numerical microprocessor equipped controller that allows to set parameters of the motor according to the application and process requirements.
