Eaton Crouse-Hinds DL143 Legend Plate - Hazardous Locations
Part Number: DL143
Quick Summary
DL143 legend plate is a compact labeling accessory for Eaton Crouse-Hinds FlexStation DL control stations used in hazardous locations. It provides Open-Off-Close inscriptions to clearly indicate switch status without opening the enclosure. Engineers often struggle with illegible or misinterpreted labels in explosion-proof cabinets, which can lead to misoperation and safety risks. This legend plate meets NEC/CEC requirements and supports hazardous-location ratings essential for Class I Zone 1 and Class II Division 1 environments, among others. With a precise 2.25 in length and a slim 0.01 in profile, it installs quickly on single-hole covers, preserving panel density while improving compliance. Using this plate reduces maintenance errors and accelerates safe operation, delivering tangible ROI for plant floor labeling.
