High interrupt rating of 400 kAIC provides strong surge tolerance, reducing the risk of equipment damage and unplanned downtime in critical power paths. This translates to measurable business value such as improved uptime, longer asset life, and lower maintenance costs in large electrical panels and switchgear installations. The NEMA 1 enclosure makes it suitable for indoor, cabinet-mounted applications where dust and minor moisture control are present, simplifying installation in harsh manufacturing or warehouse environments. The BSPD series compatibility ensures a seamless upgrade path within the Eaton Bussmann portfolio, allowing users to standardize protection devices across panels and reduce spare parts complexity. The compact footprint (14 in L x 10 in H x 10 in W) with a 12 lb weight enables straightforward mounting in standard enclosures with minimal wiring changes. Additional data such as UPC 786685934440 supports streamlined procurement and traceability, while the available specification sheet provides engineering confirmation for compliance and integration planning.

FAQs
The BSPD400240D2K uses a standard NEMA 1 footprint and is designed for indoor panel installations. It should be mounted in a suitable enclosure with access to the protected circuit, wired per the datasheet, and connected to the panel's bus or lugs as specified. Refer to the Eaton BSPD specification sheet for wiring diagrams and terminal torque values to ensure a compliant, tool-friendly installation.
The device provides a 400 kAIC interrupt rating, which indicates it can safely interrupt high-energy transients without failing. This rating is critical for protecting vulnerable downstream equipment, reducing the likelihood of insulation damage, nuisance trips, and unplanned downtime in mission-critical panels and control circuits.
Yes. With a NEMA 1 enclosure and 400 kAIC protection, the BSPD400240D2K is well-suited for indoor industrial panels, control cabinets, and switchgear applications where robust transient protection and reliable operation are essential. Its compatibility with the BSPD family also supports scalable protection across multiple enclosures.
The product notes SCAQMD compliance with manufacturer guidance, and it uses a NEMA 1 enclosure for indoor protection. While CE or IP ratings are not explicitly listed in the data, the enclosure and surge rating are aligned with typical industrial installation practices and procurement needs; always confirm specific regulatory requirements with the manufacturer for your region.
By mitigating transient surges, the BSPD400240D2K reduces unexpected equipment failures and downtime, extending the life of protective devices and downstream components. This translates to lower repair costs, fewer production interruptions, and easier maintenance planning, especially in facilities with high mains disturbance or critical process equipment.
