Overview

The ABB LF38-4 Terminal Connecting Strip (SKU: LF38-4) from ABB Electrification is engineered to expand DC voltage control capabilities in 3-pole contactor systems. This specialized accessory facilitates the series connection of poles, enabling an increase in the controlled DC voltage beyond standard contactor ratings. It is designed for compatibility with ABB LF series contactors (AF26 to AF38) and specific secable LY series strips, including the LY16-4 and LY38-4 models. The LF38-4 is essential for industrial applications requiring higher DC voltage handling, such as in specialized machinery, control panels, and advanced motor protection circuits where standard contactor ratings are insufficient. It provides a scalable solution for evolving power requirements by allowing for higher overall DC voltage management through series pole configurations. Manufactured in the USA, this component ensures secure and efficient series wiring for 3-pole connections. Key specifications include a package quantity of 1, with each unit weighing 0.040 kg. The physical dimensions are 135.20 mm (5.32 in) in length, 103.00 mm (4.06 in) in width, and 31.00 mm (1.22 in) in height. The LF38-4 is part of ABB's comprehensive range of terminal connecting strips and shorting bars, offering flexible configurations for industrial needs. While catalog data indicates compatibility with 4-pole configurations for certain disconnect switches (e.g., OT and OS series), the LF38-4 is specifically designed for 3-pole contactor applications to achieve series DC voltage increase. For detailed specifications on cable cross-sectional area and maximum permissible current in series configurations, consult the official ABB catalog to ensure proper system design and safety compliance. This component prioritizes ease of installation and maintenance, contributing to reduced downtime and optimized operational efficiency in demanding industrial environments.
