Special features
BFD with no lights (trips switch)
Feature: Three-pole bolted pressure contact switch design provides robust protection for high-current feeds and demanding switchgear environments. Business Impact: This topology minimizes arc exposure, reduces wear on contact surfaces, and extends service life, lowering maintenance costs over the asset’s lifetime. Application: Ideal for switchgear, motor control centers, and large distribution panels in industrial facilities, especially where bottom-fed arrangements simplify cabinet layouts, wiring management, and service access. Feature: Amperage rating of 1600A, with a 480V system voltage and 120V control voltage for versatile protection. Business Impact: Enables direct protection of large motors and feeders, reduces nuisance trips, and shortens downtime by delivering reliable, predictable tripping behavior. Application: Suitable for heavy industry, manufacturing lines, petrochemical plants, and power distribution installations that require high-current capacity and dependable control signaling. Feature: NEMA ratings include 1, 3R, 4, and 12, expanding the range of installation environments. Business Impact: Ensures enclosure integrity against dust, moisture, and corrosion, supporting compliant operation in harsh plants and outdoor cabinets. Application: Reliable within outdoor withstand cabinets, damp workshops, and dusty production floors across metals, cement, and food processing facilities. Feature: Fusible protection option with optional Ground Fault Relay, Blown Fuse Detection, Single Phase Protection, Kirk Provisions, and Auxiliary Contact Provisions. Business Impact: Enables coordinated overcurrent protection, enhanced fault detection, and expanded control logic for automation schemes. Application: Ideal for single-phase protection sequences and plug-in auxiliary contacts in modern switchgear retrofits and new builds. Feature: Bottom feed and bottom fuse configuration facilitates installation and service access in tight cabinets. Business Impact: Reduces wiring complexity, speeds maintenance, and improves accessibility during routine tests. Application: Compatible with Eaton switching devices, with Kirk/Auxiliary provisions available for scalable, field-upgradeable protection architectures.
