TR-N2/3 THERMAL OVERLOAD RELAY 28-40A

Highly reliable thermal overload relays FUJI thermal overload relays are designed to provide overload protection to meet the thermal characteristics of low voltage induction motors. Adjustable thermal overload relays give motors positive overcurrent protection. The starter contacts cannot be held closing under overload conditions.However, once the bimetal element has cooled, the reset button can be depressed and the motor can be restarted in the normal manner.Ordinarily this reset is carried out manually but the starter can be changed over to automatic reset by means of a screw-driver. FUJI thermal overload relay is subjected to stringent testing in the factory to check performance and actual values are calibrated with the markings on the adjustable dial. Consequently, they provide a positive protection.
