FAQs
Install near the protected load to minimize lead lengths and maximize protection efficiency. Ensure adequate enclosure clearance, proper terminal torque, and adherence to Eaton installation guidelines for bus connections. Verify that the device dimensions—3.48 in depth, 12.05 in height, and 7.47 in width—fit the MCC cavity and maintain service access. Consider labeling and preventative maintenance access for reliable operation.
Yes. SPD100240H4J is rated for 240V high-leg delta configurations with a 4W+G neutral, specifically on the B phase. When planning installation, confirm your MCC wiring matches the B phase designation and that bus configurations allow correct placement of the SPD for optimal surge capture and accessibility.
The device provides 100 kA per phase surge current protection, offering strong defense against high-energy transient events. This level of protection helps minimize motor and drive damage, reduces unplanned downtime, and supports longer asset life in demanding industrial environments with frequent starts and stops.
SPD100240H4J carries UL 1449 certification, a recognized standard for surge protection devices. While UL 1449 is documented for safety compliance, always verify regional requirements for CE marking and IP ratings in your installation area; compliance with local electrical codes may necessitate additional checks or protective measures beyond UL 1449 as part of your QA process.
Using this SPD helps reduce unplanned downtime and protects critical motors and drives from transient damage, contributing to lower maintenance costs and longer asset life. The integration with Power Xpert SPD devices streamlines diagnostics and future upgrades, delivering incremental savings through easier serviceability and enhanced protection lifecycle management.
