FAQs
Installers should connect the two-module SPD to the protected 240V delta circuit with a 4W+G configuration on the B phase, using the internal terminal block within the NEMA 4X enclosure. Ensure proper wiring per Eaton guidelines, verify surge counter operation after power-up, and confirm all terminations are tight to maintain performance under fault events.
320 kA per phase represents the device’s surge-current rating, enabling robust clamping during large transients common in industrial environments. This rating helps protect sensitive equipment such as CNC drives and PLCs, reduces the likelihood of intermediate failures, and supports longer service intervals between maintenance windows.
Yes. The SPM320240H1Y is well-suited for motor drives and PLC panels operating on a 240V delta system with a 4W+G configuration. Its two-module architecture and high surge capability provide protection for control circuits, sensors, and drives, improving uptime and protecting against transient-induced faults.
The unit carries UL 1449 and UL 1283 certifications and CSA notice/standard references, plus RoHS compliance. These certifications validate safety and performance for electrical protection devices, support compliance with electrical codes, and simplify procurement for regulated facilities and data centers.
The SPM320240H1Y includes a 15-year warranty from delivery, extending to 20 years if registered on Eaton’s SPD site. With an integrated surge counter, you can plan proactive maintenance, reduce unexpected outages, and quantify ROI through fewer repair costs and improved system reliability.
