DCC-9-40A-3R is an EV Energy Management System, specifically designed to allow the connection of a charger to the main feeder of a panel without affecting the load calculation. This unit is designed for an exterior installation. Real-time reading of the total power consumption of a panel with pre-wired current transformers (CT). Detects when the total power consumption exceeds 80% of a main circuit breaker capacity and temporarily de-energizes the charger. Automatically re-energizes the charger when the total power consumption of the main circuit breaker capacity is less than 80% for more than 15 minutes. Features are ideal for when no additional breaker slots are available in a panel. Does not affect the load calculation of a panel. Automatic utility billing of electricity consumer (particularly important for condo installations). Can be mounted on the wall or ceiling.
