Eaton Specification Sheet - LTBK150
Low-profile design reduces enclosure depth and simplifies routing in compact control panels, accelerating wiring and reducing assembly time. This translates to lower labor costs and fewer field modifications in high-density electronics enclosures used in packaging, water treatment, and material handling lines. Insulated steel construction provides rugged protection against moisture, dust, and vibration, extending service life and reducing field failures in harsh environments like chemical processing, mining, and oil and gas. FMC conduit compatibility with a straight connector streamlines terminations, standardizing installations across machines and cutting crimping or soldering steps. The 1-1/2" trade size and durable material support reliable connections in heavy-wire applications, while the compact footprint aids in tight panel layouts. NEC/CEC compliance and UL hazardous-location ratings further ensure code adherence and safer operation in chemical plants, refineries, and other hazardous facilities. Overall, LTBK150 delivers faster deployments, safer wiring, and lower total cost of ownership for industrial automation projects.
