Earth Leakage Relay

E Power Engineering offers DIN 330, an earth leakage relay manufactured by Mikro Berhad, Malaysia. This is a numerical self-reclosing earth leakage relay, with a standard DIN rail mounting, that comes with programmable current sensitivity and time delay. Further, it has programmable dead time, programmable permanent fault time, reclaim time and lock-out auto reset time along with an incorporated positive safety feature in its trip contact. It detects when the connection to the ZCT relay trip indicator lies disconnected. It has the facility to display real-time leakage current and record leakage fault current as well as for remote reset functions. To avoid any unnecessary interruptions, protection against nuisance tripping is also provided in the relay. The company provides corresponding zero-phase current transformers (ZCTs) for these relays. The ZCTs provided are of four types: ZCT40S (40 mm dia), ZCT60S (60 mm dia), ZCT80S (80 mm dia), and ZCT120S (120 mm dia) respectively.
