Portelle di chiusura
The MMCR closure door is an advanced solution for the installation of terminal blocks in light poles. Made from self-extinguishing polyamide 6.6 resin, it guarantees resistance and safety. The terminal block base and the terminal blocks themselves, also molded from self-extinguishing polyamide 6.6 resin and zinc electroalloy respectively, provide independent tightening of the conductors via AISI304 stainless steel screws.
Technical Features:
- Nominal Voltage: 450 V
- Maximum Current: 63 A for 16 mm² terminal blocks
- Fuse Holder: Sectionable for 8.5×31.5 cartridge fuses up to 10 A
- Minimum Pole Diameter: 102 mm, extendable up to 219 mm
- Number of Poles: 4
- Conductor Section: 16 mm²
- Protection Rating: IP43 on the perimeter of the cover and IP23B in the cable entry area according to CEI EN 60529; IK8 according to CEI EN 50102
- Insulation Class: Class 2 according to CEI 64-8/4
This closure door is designed to ensure a safe and reliable electrical connection, with surface treatment including phosphochromate and powder coating. The removable silicone gasket and the fixing screws with dedicated imprint heads ensure a perfect seal and easy maintenance.
