Overview

The ABB RNCG-M254 is a high-performance nylon non-armoured cable gland engineered for rail, rolling stock, and infrastructure applications. Designed to provide secure cable termination with IP66, IP68 (5 bar for 30 minutes), and IP69 ingress protection, this gland ensures reliable sealing against dust, moisture, and environmental contaminants. The M25x1.5 thread size and 10mm thread length deliver compatibility with standard electrical enclosures and junction boxes, while the 13-18mm cable range accommodates non-armoured, portable, and tray cables. With a working temperature range of -40°C to +100°C (short-term up to +120°C) and corrosion-resistant properties, this gland is optimized for harsh industrial conditions. The lightweight design and large sealing capacity simplify installation while ensuring long-term durability. Compatible with EN 62444 standards and RoHS/WEEE compliant, the RNCG-M254 is a versatile solution for demanding electrical installations. The gland features a two-piece design with a captive locking nut for secure attachment and a split seal for easy cable insertion. It is tested to withstand vibration and mechanical stress, ensuring consistent performance in dynamic rail and transport environments. The gland’s nylon construction provides electrical insulation with a dielectric strength of 20 kV/mm, while the EPDM sealing material maintains flexibility across the full temperature range. Installation requires no special tools, and the gland supports both straight and angled cable entry configurations. The gland’s compact design allows for high-density installations in confined spaces, and its UV-resistant properties ensure long-term outdoor performance.
