TI 9 C Thermal Overload Relay

Brand: Danfoss

Thermal overload relays TI 9C are used with minicontactors CI 4 for class 10 protection of squirrel cage motors where space is a premium. The relays have single-phase protection, i.e. accelerated release if phase drop-out occurs. This is particularly important for motors with delta connected windings.
