dotAutomatic Reclosing Device for ELB (ARELB) ?
ARELB acts reclosing a circuit breaker automatically to improve the electrical service continuity after a momentary trip of ELB (earth leakage breaker). To reduce probability of hazard to personal and equipments, and to reduce time loss, ARELB has electronic intelligences to distinguish the trip has been caused by momentarily fault or not, and try to check the line state safe or not, even if the breaker has been closed again. And also to check after certain fault and reclosing, ARELB has a memory system to record the history of trip, check and reclose, as like a black box.
dotProspected Merits
educe manpower and maintenance expense
Conformation of safety before reclosing ELB
Steady supply of electricity to remote and no personnel working inside sites
Maximize the Equipment operation efficiency
Satisfy for the customer service requirement
