Description

TeSys Deca Thermal Overload Relays

The TeSys D series from Schneider Electric offers high-performance contactors and overload relays for motor control and protection applications. Designed to meet the latest industrial standards, the TeSys D range ensures reliable switching, long electrical life, and compact installation in control panels.

Engineered for both AC and DC motor starters, the TeSys D contactors support up to 150A (AC-3) and are ideal for frequent operation and integration into automated systems. Paired with thermal or electronic overload relays, the system provides full motor protection against overload, phase failure, and phase imbalance.

For electrical devices such as high-functioning motors, thermal relays provide dependable protection against overload or phase failure.
