Terminal blocks M186/1 are designed for recessed installation inside light poles, offering a robust and reliable 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 zinc alloy, three-way per pole, with anti-corrosion galvanic treatment
- Conductor tightening: Independent, through stainless steel screws AISI304
- Nominal cable section: Input-output up to 16 mm², derivation up to 4 mm²
- Nominal voltage: 450 V; Maximum current: 63 A
- Fuse holder: Detachable, for 8.5×31.5 mm 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 degree: IP43 around the cover; IP23 in the cable entry area, according to CEI EN 60529; IK8 according to CEI EN 50102
These terminal blocks ensure safe and reliable connections inside light poles. The enclosure and base, made of self-extinguishing polyamide resin, along with zinc alloy terminals treated with galvanic protection, offer excellent resistance to corrosion and weathering. With a capacity of up to 16 mm² and a maximum current of 63 A, they are suitable for applications requiring robustness and reliability. The IP43 and IP23 protection ratings, combined with insulation class 2, ensure adequate protection for electrical connections in outdoor environments.

TERMINAL BLOCK FOR CABLE CONNECTIONS model M186/1
The M186/1 terminal block, supplied by NCM, is designed to provide a reliable electrical connection inside poles. Made from self-extinguishing polyamide 6 resin, it ensures double insulation (class 2) according to CEI 64-8/4 standards. The terminals are made from three-way zinc alloy per pole with anti-corrosion galvanic treatment, allowing for independent conductor tightening through AISI304 stainless steel screws. It supports a nominal cable section up to 16 mm² for input-output and up to 4 mm² for derivation. The disconnectable fuse holder accommodates 8.5×31.5 cartridge fuses up to 10 A. Suitable for recessed installation in poles with a minimum diameter of 102 mm, it is certified with an IP43 protection rating around the cover perimeter and IP23 protection in the cable entry area, along with IK8 impact resistance according to CEI EN 50102.
