Description
Fuji electric 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 overcuttent 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 testrarted and the motor can be restrated in the normal manner. Ordinaryly this reset is carried out manually but the starter can be changed over to automatic reset by means of a screw-driver.
Peringatan
All Fuji thermal overload relays have been tested and calibrated at the factory. They should not be tampered with or stripped down at the job site since this would affect their accuaracy. A special feature of the Fuji starter series is the ease by which the relay current ratings can be varied to match teh requirements of the load. The changeover is effected by simply turning a dial to the new value required. The range of adjustment is approximately 100%-125%-150% and detail are given overleaf.Ulasan Produk
