Industrial GTK-12M-2.5

GTK-12M-2.5 is a MINI overload relay from Altech Corporation designed to provide motor overload protection when paired with compatible GMC/GT contactors in industrial control circuits. It is rated for overload currents in the 1.6–2.5 A range and carries Class 10A protection with a differential-type trip (typical), making it suitable for small-motor starters. The GTK-12M family uses a broad selection of coil voltages to fit a wide range of control voltages; AC options include 24, 36, 42, 48, 110, 115, 120, 127, 200/208, 220, 230/240, 256, 277, 380/400, 400, 440, 480, 500, 550, and 600 V, while DC options include 12, 20, 24, 36, 42, 48, 60, 72, 110, 120, 125, 220, 240, and 250 V. As a MINI-style relay, GTK-12M-2.5 is designed to integrate with standard Altech contactors to form compact motor protection assemblies and is documented in Altech’s product literature and catalogs.
