The electricity distribution and metering cabinet (FDCP) is an integrated part of the electricity supply installation, at 400 V rated voltage between phases, in apartment buildings, commercial, socio-cultural and administrative buildings.
Functions:
- Connection of the energy installation of the apartment buildings consumers or city buildings to the supplier’s energy installation;
- The energy supply can be ensured through one group of fuses, 2 groups of fuses or an automated circuit breaker according to the beneficiary’s demands;
- Measurement of the active energy used by each consumer and the possibility of reading the meter independently of the consumer’s presence at the measuring time;
- Protection against overload, short-circuit and residual differential currents for each consumer’s main energy supply;
- Protection against industrial frequency over-voltages occurred at each consumer, through the neutral’s accidental interruption;
- Protection against electrocution through direct contact with the live circuitry and devices;
- Protection against energy thefts and electrical equipment damages determined by the action of an ill-intended, unknowing or unauthorized person;
- Creating possibilities to limit the load peaks and reduce the technological losses;
- Protection of the consumer against industrial frequency over-voltages.
Components:
- The metallic box made of sheet metal powder coated in electrostatic field, coated accordingly to the operating conditions, respectively indoor or outdoor;
- Racking for the installment of the electrical devices;
- Meters for measuring the energy consumption;
- Single phase consumer’s mains made with: LF fuses or automated circuit breakers with over-voltage and differential protection.
The box contains 3 compartments:
- Compartment for fuses;
- Compartment for connection, protection and signaling devices;
- Compartments for meters.
