ELMEASURE 3 PH - ACCL 100A Preset Electronic Timer Switch  (White)

ElMeasure's Intelligent Automatic Changeover with Current Limiter allows supply from mains as long as the load current is below the programmed current. When the mains supply fails and stand by generator supply is on, it connects the DG power to each consumer in sequence & starts monitoring its load. Whenever the load current exceeds the allotment, power is automatically switched off for 10 seconds, and automatically restored. This cycle repeats for 5 times each time with double the time (20, 40, 80 & 160) and then enters into lockout mode until it is 'Reset' manually. Apart from Over load on EB and DG protection it also protects against over voltage from DG side.
