Feature: The SPD100240D4B delivers a robust 100 kA per phase surge rating, providing essential protection for critical loads in switchgear during fast transients. This UL 1449 listed device markedly reduces the risk of transient overvoltages reaching downstream equipment, safeguarding motors, drives, sensors, and control logic in demanding environments. Designed for easy integration into existing protection schemes and for seamless mounting within standard Eaton switchgear footprints, it supports fast deployment on both new builds and retrofits. Feature: Configured for 240 Delta (3W+G) operation, it aligns with Eaton’s Power Xpert SPD family and switchgear platforms, ensuring consistent protection across distribution networks. Business impact: Accurate phase grounding and system balance minimize nuisance trips, misoperations, and thermal stress on feeders, extending equipment life and reducing energy waste. Application: Ideal for distribution panels, motor control centers, and other complex electrical installations where reliable surge protection is essential. Feature: Compact footprint—3.48 in depth, 7.47 in width, and 12.05 in height—with a weight of 6.8 lb, enabling straightforward insertion into crowded panels. Business impact: Easy mounting and serviceability reduce installation time, commissioning costs, and on-site labor while preserving wiring clearance. Application: Retrofit projects in existing panels or new build-outs with limited space. Feature: Remote display capability enhances monitoring and fault diagnosis, delivering real-time status without panel access, which simplifies maintenance cycles. Business impact: Proactive maintenance and quicker fault isolation save labor hours, minimize unplanned downtime, and extend equipment life across complex lineups. Application: Centralized protection strategy within Power Xpert SPD ecosystems and Eaton switchgear. Feature: Seamless Eaton compatibility simplifies procurement, spare parts management, and service workflows, facilitating a single-source strategy for protection devices. Business impact: Consolidated logistics lowers total cost of ownership, improves parts availability, and speeds field service with consistent interfaces. Application: Industrial plants, data centers, and machinery fleets relying on consistent surge protection across distributed assets.
