Thermal relays

Reels are normally used for
the protection of motors against overloads that prevents their operation
Monophasic.
Thermal relay is used in AC 50/60 Hz circuits, working voltage
rated up to 690V and current from 0.1A to 630A. Maybe.
integrated into multiple function apparatuses; such as contacter,
contacters-interruptors or be installed independently.
The correct protection against overloads is relevant to increase the
life time of the engines, preventing the operation in
abnormal heating conditions while ensuring continuity
the service of machines, equipment and installations, and prevent
