Thermal Overload Relays

Electrical Distribution & Industrial Control | Electrical Distribution & Industrial Control

Fuji Electric offers the SK Series Mini Contactors, which is up to 5HP at 480VAC, the SC-E Series Contactors, up to 100HP at 480VAC, and their associated thermal overload relays; the TK12 Series and TK-E Series, respectively. Our flagship contactor lines, The Orange Line and Odyssey Series Contactors are also available. The Orange Line Series is available up to 10HP at 480VAC, while the Odyssey series is available up to 300HP at 480VAC. The Orange Line/Odyssey Series’ features the electrically-controlled Super Magnet operation, leading to a no unstable zone. The unstable zone is where chattering, contact welding, or coil burning often occurs. Chattering is a phenomenon which occurs when the gravitational force of the starter magnet, decreases through the line voltage drop at the time of motor starting. This may cause damage such as contact welding or coil burning.
The Super Magnet accepts either AC or DC coil control voltage. They are designed to globally accepted approvals and ratings, engineered for quality performance, day after day offering a wide variety of frame sizes - up to 700HP.Overload relays feature open phase protection and Contactors through 10HP at 480V offer industry's longest life expectancy - 2 million electrical operations. Orange Line, up to 10HP@ 480 VAC "Logic level" aux contacts allow consistent operation down to 5VDC 3mA. Overloads offer "Open phase protection" as a standard feature
