The N series motor protection relays from NewElec offer a wide variety of alternative mounting solutions within the 5 to 550 amp range in amp calibration or any current range in the percentage calibration. These include CT module block, chassis or flush door mounting. N Series relays are designed for simplicity without compromising reliability. The relays offer coordinated tripping on potentially high energy faults, ensuring that the main contactor is not used to clear such faults. A duplication of trip and fault annunciating NO contacts provides control rooms with a hard-wire solution for information and reset possibilities.
The relays are housed in a versatile enclosure which caters for door mount, chassis mount or CT module mounting. Protection features include selectable thermal curves (Class 5 – 32.5) with thermal pre-loading to match the safe hot and cold stall times of the motor during operation.
N Series relays are designed to IEC 60255-8 and provide overload protection for cyclic or sustained loads, as well as unbalanced current, single phasing, earth leakage and earth fault protection. The user has the option of transferring the trip to the incoming MCCB to prevent the contactor opening on high energy faults, ensuring type 2 co-ordination.
