A thermal relay, also known as a thermal overload relay, is a protective device used in electric motors to prevent damage caused by thermal overload. The main function of the thermal relay is to monitor the motor's temperature and disconnect the electrical power if the temperature exceeds a certain safe limit. Thermal relays are crucial components in industrial applications where electric motors are widely used. They help protect motors from damage caused by thermal overload, extending equipment life and improving system reliability. Tesys Deca thermal overload relay 16-24A class 10A 1NO+1NC Tesys Deca relays are designed for Tesys Deca contactor lines, demonstrating safe and effective protection. This product has a thermal adjustment range of 16-24A/690V, trip class 10A, and is intended for the protection of three-phase motors under 11kW/400V. This relay is a differential device with phase failure (loss). It provides a thermal adjustment dial, a manual-automatic reset selector, a test button for trip simulation, reset and stop buttons, an alert indicator, and two auxiliary contacts (1NO+1NC) for fault signaling. The settings are protected by a transparent cover that can be locked by sealing. Its connection is made via screw terminals, connecting directly to the lower terminals of 3-pole LC1D25-D38 contactors, or separated from the contactor, using a LAD7B106 terminal block (to be ordered separately). It can be mounted on a DIN rail or with screw fastening. This product is multi-standard certified (IEC, UL, CSA, CCC, EAC, ATEX, Marine). Tesys Deca overload relays carry the Green PremiumTM seal, which promises compliance with the latest regulations, transparency in environmental impacts, circular, and low CO2 products.
