TeSys Deca Thermal Overload Relays

Thermal overload relay with manual or automatic reset from 0.1 to 150 A and 0.06 to 75 kW

Part of TeSys

As the industrial sector is highly vulnerable to hazardous fire breakouts, short circuits, and explosions, industries use multiple protection devices like thermal overload relays to safeguard their employees and assets from irreversible loss and damage.

Thermal relays offer reliable protection for electrical instruments like high-functioning motors in events like phase failure or overload.

Thermal overload relays are used across multiple electrical applications like fans, mixers, pumps, compressors, elevators, compressors, and more. These relays offer several benefits like cost efficiency, adjustable current range, effective operating principle, and more. At Schneider Electric India, we carry a diversified portfolio of thermal overload relays under our exceptionally designed range called TeSys. Safe and effective protection.

With its integrated manual-automatic reset and simple installation in screw clamp terminals, by spring terminal, by ring terminals and by EverLink terminals version, model LRD thermal overload relays are very reliable and cover the whole range of motor ratings up to 150 A. They can be combined with TeSys d contactors to form an extremely compact starter.
