Overview

The ABB LY38-4 Secable Connecting Strip (SKU: LY38-4) is a precision-engineered accessory designed to connect poles in series for 3-pole contactors, enabling a significant increase in DC voltage control. Specifically compatible with ABB LP and LY series contactors—including LY16-4 and LY38-4 models—the LY38-4 facilitates elevated DC voltage ratings by linking multiple poles in series, a critical function for applications requiring higher voltage operations beyond individual pole capabilities. This secable connecting strip is part of ABB’s terminal connecting strip and shorting bar portfolio, optimized for custom configurations such as star points (3 parallel-connected poles) or parallel connections to boost AC load capacity in LP, LY, LH, LF, and LG series contactors. However, its primary application is series DC voltage enhancement, where the maximum nominal continuous current in series configurations depends on the cable cross-sectional area. For example, with a 10 mm² cable, the LY38-4 supports specific current ratings in series setups, ensuring safe and efficient operation within defined limits. Manufactured by ABB Electrification, the LY38-4 is a lightweight (0.012 kg) accessory with a compact design, packaged in quantities of 10 per bag. Its durable construction ensures long-term reliability in industrial environments, making it a dependable solution for complex electrical systems. The product is classified under ETIM 4/5/6/7 as an accessory for low-voltage switch technology, aligning with ABB’s AF contactor series. For optimal performance, consult ABB’s cable cross-sectional area tables to verify maximum permissible current ratings and maintain safe operation. Key applications include industrial motor control systems, automation panels, and power distribution setups where series DC voltage enhancement is required. The LY38-4 integrates seamlessly with ABB’s AF contactor ecosystem, providing a reliable method to achieve higher DC voltage levels without compromising system integrity.
