Introduction
TeSys Master Range
TeSys is an innovative motor control and management solution from the global market leader. TeSys offers connected, efficient products and solutions for switching and protection of motors and electrical loads in compliance with all major global electrical standards.
Presentation of the TeSys H Motor Starter
At only 22.5 mm wide, the TeSys H is an ultra-compact motor starter.
Using hybrid technology that combines electromechanical relays, power solid-state components, and a solid-state overload function, the TeSys H motor starter controls and protects three-phase motors up to 3 kW/500 V or resistive loads up to 9 A/500 V.

FALSE-TRIP HAZARD ON NON-SINUSOIDAL THREE-PHASE VOLTAGES
Do not use the TeSys H motor starter on the power side or load side of a variable speed drive or
soft starter.
Failure to follow this instruction can result in false
trip.

FALSE-TRIP HAZARD ON SINGLE-PHASE VOLTAGE
Do not use the TeSys H motor starter to control and protect single-phase loads.
Failure to follow this instruction can result in false
trip.

Motor Control
The TeSys H motor starter is used to switch on and switch off three-phase, asynchronous electrical motors used in single-direction or dual-direction applications. The TeSys H motor starter protects the motors against overheating.
Safe Torque Off (STO)
STO TeSys H motor starters LZ7H and LZ8H are designed for use in safety chain applications.
Safety shutdown can be achieved to the following standards:
-
SIL3 according to IEC61508-1
-
PLe according to ISO13849-1
TeSys H motor starters LZ7H and LZ8H are ATEX certified as associated components for motor protection.
