Thermal overload relays TI 9C are essential components designed to work seamlessly with minicontactors CI 4, providing class 10 protection for squirrel cage motors, particularly in environments where space is limited. These relays offer critical single-phase protection, ensuring rapid release in the event of phase drop-out, a feature especially vital for motors with delta-connected windings. Equipped with a stop/reset button for easy operation, they offer both manual and automatic reset options, providing flexibility according to specific requirements. Additionally, a test button allows for convenient functionality testing. With a double scale for direct start or Y/D (star-delta) start configurations, these relays accommodate diverse motor setups. Moreover, the inclusion of a signal contact with changeover or galvanically isolated options enhances compatibility and safety, making the TI 9C relays an indispensable choice for motor protection needs.
