N Series Relays

*Compulsory fields.

The N Series electronic motor protection relays are housed in a versatile enclosure which caters for door mount, chassis mount or C.T. module mounting.

Protection features include selectable thermal curves (Class 5 – 30) with thermal pre-loading to match the safe HOT and COLD stall times of the motor during operation.

Designed to IEC 60255-8, the N Series provide overload protection for cyclic or sustained loads, as well as unbalanced current, single phasing, earth leakage and earth fault protection, with an option to transfer trip to incoming MCCB to prevent contactor opening on high energy faults, ensuring type 2 co-ordination.

PLC interface via remote I/O can be implemented, a 4-20mA output indicating motor load current as well as individual potential free N/O contacts for thermal lock-out, overload, unbalanced current and earth leakage. Resetting or clearing the fault latch can be performed by pressing the control panel mounted push button, momentarily bridging terminals 11 and 12, or by providing a reset pulse of 24 to 240V AC or DC between terminals 33 and 34.
