NewElec's N Series motor protection relays offer the user a choice of protection features, mounting options, and a choice of appropriate motor thermal curves with five models to choose from. When used with their own integrated current transformers, which incorporate an earth leakage core balance C.T. in the same housing, and the inclusion of a 4 to 20 mA loop for monitoring motor loads, significant space and cost savings are achieved.
The relays are reliable and provide overload protection with user-adjustable cold and hot thermal curves linked to a comprehensive thermal memory. The user has the ability of selecting the appropriate thermal curve for the power rating of the protected motor. This allows the motor to work hard but within its designed thermal envelope. Excessive jogging of the motor will not be tolerated, and the cooling time after an overload trip is never compromised.
Earth leakage protection with a 250 mA sensitivity and a 100 ms trip delay including harmonic filtering enables D.O.L. starting of high-powered motors without accompanied nuisance trips on start up. These relays also recognise the potential danger of opening the main contactor on potentially high-energy faults and provide co-ordination so that either the trip is blocked if the earth fault current exceeds a safe level, or use is made of a dedicated earth fault trip contact designed to operate the back-up circuit breaker on detection of such faults.
