Product description

Destination:

The low-voltage connection plug type E, EMP is intended for use in the electrical distribution network for supplying electricity to domestic consumers (apartment blocks, villas, etc.) and building constructions.

Symbolism

Low-voltage connector type E [X][Y], with metal casing
Low-voltage connection plug type E [X][Y] MP, with glass fiber reinforced polyester housing where:
    • X number of input circuits 1 ... 5
• Y the number of output circuits 2 ... 8

Features:

• provides short circuit protection
• ensures visible separation for the protection of operating personnel
• ensures the creation of power supply loops in the urban network. The three-phase power supply column made with MPR type fuses or vertical three-pole separators with MPR cartridges both on the input and on the output

Constructive characteristics:

The low-voltage connection plug type E, EMP is made in the following constructive variants:
• Metal box for outdoor birds, with/without socket
• Semi-buried rack with door for indoor birds
• Polyester box reinforced with fiberglass, with/without socket

The cables can be connected using cable lugs or V-clamps with hex head screws for sections 35-120 mmp, 70-240 mmp.

The doors are provided with special locks with 2-point locking, with a key that allows sealing and locking with a padlock, protection against the theft of electricity.

The body of the box is made of metal or polyester reinforced with glass fiber resistant to mechanical shocks, weather, fire and solar radiation.

Inside the box there are:
• metal rack made of steel profiles protected against corrosion and painted in an electrostatic field, for supporting the power supply columns (three-phase with MPR fuses, vertical separators with MPR, at the customer's request)
• V-clamps provided with hex head screws for connecting electricity, sections 35-120, 70-240 mm2
• the input of the connection and the output of the power supply columns of the distribution board to the subscriber, is done through the bottom corresponding to their nominal currents, protective neutral terminals are also provided for connecting the protective conductor from the protective belt

The box is provided with a front access door secured with two-point locks and the possibility of sealing.
