Feature: 400 kAIC interrupt rating delivers robust surge suppression for high-energy transients. Business impact: dramatically reduces the risk of transformer and drive damage, lowers repair costs, and minimizes unplanned downtime across critical loads. Application: ideal for heavy-industry motor control, servo drives, and data-center floor equipment where transient events frequently occur. Feature: NEMA 4X enclosure provides weatherproof, corrosion-resistant protection for indoor and outdoor installations. Business impact: extends service life in washdown areas, outdoor switchgear, and exposed panels, reducing maintenance cycles and replacement parts. Application: suitable for manufacturing floors, outdoor MCCs, and process areas where environmental exposure would otherwise compromise protection equipment. Feature: Clear physical footprint—14 in length, 10 in width, 10 in height, and 18 lb weight—enables flexible placement in existing panels. Business impact: simplifies retrofit projects, reduces installation time, and lowers shipping costs for field personnel. Application: compatible with standard electrical cabinets and motor control centers, facilitating quick integration into new builds or upgrades. Feature: SCAQMD compliance noted, with guidance from the manufacturer, adds regulatory alignment for regional operations. Business impact: supports environmental and safety audits, avoids potential fines, and accelerates site approvals. Application: plants in districts with stringent air-quality rules implementing protective devices across feeders and main panels to safeguard operations. Feature: BSPD series compatibility ensures a consistent protection platform across Eaton products. Business impact: streamlines procurement, reduces spare parts inventory, and simplifies technician training with a common interface. Application: multi-panel facilities and OEM projects that plan to deploy surge protection devices throughout distribution boards and panelboards. Feature: Easy installation and service access supports rapid commissioning and ongoing maintenance. Business impact: reduces downtime during upgrade projects, enables proactive diagnostics, and supports a lower total cost of ownership. Application: field crews gain efficiency when installing in new builds or retrofits, ensuring reliable protection across critical electrical assets.

FAQs
Install BSPD400240D3P in a suitable enclosure with a NEMA 4X rating and comply with local wiring codes. Verify panel space, mounting clearance, and conductor routing before mounting, then connect to the incoming feeder or panelboard per Eaton’s wiring diagrams. Use the UPC 786685934471 for part verification and keep spare BSPD units on hand.
The 400 kAIC interrupt rating is ideal for high-energy surges in motor drives, servo systems, data centers, and critical manufacturing lines where transient events threaten uptime. It provides rapid response, minimizing voltage overshoot and device stress. Pair with upstream protective devices and ensure proper coordination to maintain service continuity.
Yes. The BSPD400240D3P uses a NEMA 4X enclosure that resists moisture, dust, and corrosion, enabling outdoor installations and washdown areas. When located outdoors, ensure gland entries and conduits are sealed, and that temperature and humidity are within the device ratings. Regular inspection of enclosure integrity is recommended.
It complies with SCAQMD guidelines as indicated by the manufacturer; for other regional requirements, consult the Eaton datasheet and your local authority. In operations requiring CE or IP ratings, verify with the supplier or perform a formal conformity assessment. Document the enclosure rating, surge rating, and installation method for audits.
Adding this SPD reduces unplanned downtime by protecting critical assets from transient surges, resulting in lower maintenance costs and fewer component replacements. The compact 18 lb unit simplifies handling, installation, and future upgrades, reducing field labor. Over the equipment lifecycle, the BSPD400240D3P delivers predictable protection, improved uptime, and a faster path to regulatory-compliant, reliable operation across sites.
