Schneider Electric TeSys H compact motor starters

Schneider Electric has introduced TeSys H, a 22.5 mm-wide multifunctional, ultracompact starter for electrical motors. The product is designed to save space in control cabinets and can be used in a variety of industries, including food and beverages, logistics and durable goods. It is also a suitable starter solution for machines in material handling and packaging systems.

The unit can provide up to four functions: forward running; reverse running; protection against overload, phase imbalance, phase loss, stall and jam; and safe shutdown up to SIL3 according to IEC61508-1 (available in the Safe Torque Off variant). It provides up to a 75% space reduction — making it suitable for all control cabinets where saving space is a priority — and a 60% reduction in installation time.

The motor starters are available in two models dedicated to different applications. Bearing a green label, the standard TeSys H is meant for standard applications and provides the three functions of forward running, reverse running and protection. It is equipped with a fault auxiliary contact, three reset options (manual, remote and automatic), a wide setting range (0.18 to 2.4 A and 1.5 to 6.5 A) and control voltage (24 VDC or 110–230 VAC), and four LEDs for easy diagnostics.

The red-labelled TeSys H, the Safe Torque Off model for safety chain applications, includes an additional safe shutdown function. This model meets the requirements of functional safety and is rated SIL3 according to IEC 61508-1.
