Product Overview
The DR150-12N is a ring lug from CEMBRE, part of the DR150-N family. The product is specified for a conductor cross-section of 150 mm² and uses an M12 fastening screw with a screw hole diameter ØD = 13 mm. Supplier's item number: 2389224. The product is marked as RoHS compliant and refers to standards DIN 46235 and UL486A-486B.
Function and Construction
The DR150-12N is designed as a ring terminal for connecting a single conductor. According to the manufacturer's product description, the DR series is manufactured with electrolytic copper tubing with a purity of more than 99.9%. The terminals undergo processing such as annealing and electrolytic tinning, which, according to the manufacturer, facilitates compression (crimping) and increases mechanical resistance. The collar length and a chamfered entry edge are designed to facilitate conductor insertion and simplify use in crimping tools. The surface treatment is tin plating, and the crimp geometry is stated as hexagonal.
Mounting and Torque
- Screw: M12 (screw hole diameter ØD = 13 mm).
- Stated tightening torques on the manufacturer's page: 40 Nm for high-conductivity screws; 50 Nm for 8.8-grade screws.
Documentation and Compliance
The product is stated as RoHS compliant and is listed in the manufacturer's documentation with reference to DIN 46235 and UL486A-486B. The general DR series description on the manufacturer's website describes material composition, surface treatment, and crimp geometry as stated above.
