FAQs
SPD100240H4C requires a compatible 240V high-leg delta supply (4W+G on B phase) and mounting space that matches its 7.47 x 12.05 x 3.48 inch footprint. Ensure the panel or busway is rated for surge protection device installation and that wiring aligns with the provided terminal connections. Refer to the Eaton datasheet for mounting guidelines and PRL compatibility (PRL1a, 2a, 3a, 3e, 4) to plan a seamless retrofit.
The device is rated for 100 kA per phase, providing high-energy absorption during transient events. UL 1449 certification confirms compliance with critical safety and performance standards. In practice, this translates to reduced voltage transients reaching protected equipment, minimizing nuisance trips and component wear, and enabling quicker recovery after surge events in switchgear and panel assemblies.
Yes. SPD100240H4C is designed to work within Eaton’s protection ecosystem and is listed as an accessory option for Power Xpert SPD configurations. This compatibility enables centralized protection strategies, streamlined maintenance, and easier expansion to cover additional panels or busways without replacing existing protection hardware.
The SPD100240H4C is UL 1449 certified, validating safety and performance for surge protection devices used in electrical distribution. This certification supports regulatory compliance during audits and aligns with common industry requirements for protection against transient overvoltages in commercial and industrial installations.
By limiting surge-related damage and reducing nuisance outages, the SPD100240H4C can extend the life of connected equipment and lower maintenance costs. Its compatibility with Power Xpert SPD and standard PRL-ready form factor simplifies upgrades and replacements during panel refurbishments, enabling faster downtime recovery and improved total cost of ownership for critical facilities.
