FAQs
Install the SP3-240S into standard Eaton SP3-compatible panelboards by ensuring the power is disconnected, aligning the device with the panel bus, and securing the unit according to the manufacturer’s mounting guidelines. The 120/240V split-phase design supports straightforward wiring, but adherence to local codes and proper torque on connection lugs is essential for reliable operation.
The SP3-240S provides a 50 kAIC surge current rating and operates on a 120/240V split-phase system. This combination targets high-energy transients typical in industrial environments, helping to minimize the impact of lightning and switching surges on connected equipment and panels.
Yes. The SP3-240S is part of the Eaton SP3 surge protection family, designed to integrate with SP3-series protection schemes. This compatibility simplifies ordering, stocking, and installation, especially when upgrading or expanding existing protection across multiple panels.
The provided data does not list specific certifications for the SP3-240S. To verify compliance, consult the official Eaton datasheet or contact a distributor for stamped certifications (such as CE or IP-related marks) and any UL/IEC references applicable to your installation site.
Installing the SP3-240S can reduce unplanned downtime by protecting critical loads from transient surges, extending the life of downstream equipment, and lowering maintenance costs associated with surge damage. The compact form factor and straightforward integration help speed commissioning, improving overall uptime and total cost of ownership in industrial facilities.
