B, relay will disconnect, relay status turns from connected to ready for
reconnection
➢ After relay is disconnect, it will keep this status for a preset time C, relay will
turn connected and detect the load again
➢ If overload counts more than D times, relay will not execute off/on again, relay
will keep the initial status(consumer can decide to turn off or on by himself), this
initial status called G.
➢ If overload does not happen in E minutes, the meter will restart the overload
counts.
