Doors and Terminal Blocks

The closure doors made of aluminum alloy, complete with terminal blocks model P186+M186/2, are designed for applications on poles with diameters ranging from 102 to 300 mm. The door is made of die-cast aluminum alloy, with surfaces treated via phosphochromating. It includes a removable EPDM rubber gasket and AISI 304 stainless steel fixing screws with a pentagonal imprint for a dedicated key. The aluminum clamping brackets provide anti-slip functions. The device ensures an IP55 protection rating and IK10 impact resistance.

The M186 terminal block is housed in a self-extinguishing polyamide resin 6 enclosure and includes zinc electro-alloy terminals with anti-oxidation treatment. It supports cables up to 16 mm² for input-output and up to 4 mm² for derivation, with a maximum capacity of 63 A and a rated voltage of 450 V. It is equipped with two fuse holders for 8.5×31.5 mm cartridges (up to 10 A). Classified as Class 2 according to CEI 64-8/4, it offers IP43 protection on the cover perimeter and IP23 at the cable entry zone, with IK8 impact resistance.
