Carlo Gavazzi GT6340A Screw Type Thermal Overload Relay

Carlo Gavazzi GT6340A screw-type thermal overload relay provides motor protection by interrupting current when a motor draws more than the set limit. This bi-metal overload relay is designed for direct mounting to contactors and offers an adjustable trip current range of 28 A to 40 A, with a nominal rating of 63 A as indicated by the model labeling. It is rated for an operating voltage up to 690 V (Ue) and employs a trip class 20 setting to balance reaction time and nuisance trips. The device includes one normally closed and one normally open auxiliary contact, enabling simple integration into control circuits for status feedback and interlock functions. For installation, it supports direct mounting on a contactor via screw clamps, simplifying wiring and ensuring secure, field-adjustable protection for AC motors in industrial applications such as conveyors, pumps, fans, and machine tools.
