GELCO has developed an electronic overload relay based on ic technology. It protects motor against overloading, single phasing and reverse phasing. It gives single phasing protection upto motor terminal. As it is with current sensing single phasing preventer, it is very slim and compact. Ct's are in – built. It is available in various range. Thermal overload relays can be replaced by this electronics overload relay. No separate single phasing preventer is needed. It weighs 510 gms approx. And measures 110mm x 65mm x 85mm approx.
