DISTRIBUTION PANEL WITH DEMAND CONTROL

摘要

PURPOSE:To surely prevent the demand control function of a distribution panel from being damaged due to an erroneously thrown blocked load from a branch breaker when an overcurrent occurs. CONSTITUTION:Circuits which respectively have polarity inverting functions corresponding to the polarity inverting function of an auxiliary switch 53a and are composed of a change-over switch 52 and the first and second diodes 54 and 55 are connected to remote control relays 13a-13d provided with main contacts 50a and 50b connected between branch breakers 8a-8d and loads and the auxiliary switch 53a. In addition, an arithmetic processing section 30 which switches the switch 52 to different contacts between the monitoring mode of the collectively turning off mode time and collectively turning on mode time is provided.
