Ring cable lug: Cembre DR50-8N
The DR50-8N is a ring cable lug from the Cembre DR‑N family, designed for copper conductors and manufactured in accordance with DIN 46235. The product is specified for 50 mm² conductors and uses an M8 screw (ØD 8.4 mm). The description below is based on Cembre's technical documentation for the DR‑N series.
What is and what does the DR50-8N do
- The DR50-8N is a tubular cable lug (crimping lug) designed to terminate copper conductors.
- Provides mechanical and electrical connection between conductor and screw connection using an M8 screw.
- Materials: electrolytic copper with purity stated as over 99.95% and a surface treatment with tin plating.
Installation and assembly
The installation instructions in the manufacturer's documentation specify the necessary steps for correct crimping. The following points are explicitly stated for DR50‑N in the datasheet:
- Select the correct connector for Cu conductor of 50 mm².
- Select appropriate crimping tool and dies as indicated (for DR50‑N, MK14 dies are referenced, among others).
- Strip conductor to the recommended length: 31 mm for DR50‑N.
- Insert the conductor into the lug and apply the recommended number of crimps: 3 crimps, starting from the tang side of the lug.
The datasheet also specifies an operating temperature for the DR‑N series from -50 °C to +150 °C and notes that the products are intended for use with copper conductors. Cembre offers technical documentation for the DR‑N series on their website.
