Tesla D1321 | Thermal Overload 12-18Amp

Tesla D1321 | Thermal Overload 12-18Amp

The Tesla D1321 is a thermal overload relay with an adjustable range of 12 to 18A, designed to protect larger motors from sustained overcurrent and overheating. It pairs with D09 to D32 contactors and provides accurate, time-delayed protection by simulating how a motor heats up under load. This makes it essential in industrial automation and heavy-duty motor control systems.

Unlike circuit breakers that react instantly to short circuits, the D1321 responds to ongoing overload conditions. This helps prevent unnecessary shutdowns while extending motor life. It features manual or automatic reset options and a standard mounting design for straightforward integration into control panels and motor starters.
