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 in five models. When used with their own integrated current transformers, which incorporate an earth leakage core balance CT in the same housing, and the inclusion of a 4-20 mA loop for monitoring motor loads, significant space and cost savings can be achieved.
N Series 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 kW 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 DOL starting of large kW motors without nuisance trips on start-up. N Series relays recognise the potential danger of opening the main contactor on potentially high energy faults. They 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.
LED and remote relay fault indication is available if required.
