The M186/2 terminal blocks are designed for recessed installation inside light poles, providing a robust and versatile solution for cable connections in outdoor environments.
Technical Features:
- Enclosure: Molded in self-extinguishing polyamide 6 resin
- Terminal Block Base: Molded in self-extinguishing polyamide 6 resin
- Terminals: Molded in three-way zinc alloy per pole with antioxidant galvanic treatment
- Conductor Tightening: Independent via AISI304 stainless steel screws
- Nominal Cable Section: Input-output up to 16 mm², derivation up to 4 mm²
- Nominal Voltage: 450 V; Maximum Current: 63 A
- Fuse Holder: Dual disconnectable fuse holder for 8.5×31.5 cartridge fuses up to 10 A
- Pole Diameter: Minimum 102 mm for recessed installation
- Insulation Class: Class 2 according to CEI 64-8/4
- Protection Rating: IP43 around the cover perimeter; IP23 in the cable entry area according to CEI EN 60529; IK8 according to CEI EN 50102
These terminal blocks offer advanced protection thanks to the dual fuse holder, making them ideal for applications requiring additional protection. The enclosure and base made of self-extinguishing polyamide 6 resin, along with the zinc alloy terminals treated with galvanic coating, ensure high resistance to corrosion and weathering. With a cable section capacity of up to 16 mm² and a maximum current of 63 A, they ensure secure and durable connections. The protection ratings of IP43 and IP23, along with the Class 2 insulation, provide adequate protection for outdoor installations.
