FAQs
Install the SPC150480Y8P as an external side mounted device on a 277/480V Wye system. Follow the wiring diagram in the Eaton datasheet, connect line and load terms correctly, and wire the alarm and Form C relay to the control system for remote status signaling. Ensure proper grounding, torque connections per spec, and verify enclosure integrity before commissioning.
The 150 kAIC rating indicates the device can safely absorb and interrupt up to 150 kiloamperes of surge current at the specified voltage. This reflects strong protection for high-energy transients. Actual performance depends on proper installation, coordination with downstream protections, and adherence to the manufacturer’s commissioning guidelines.
Yes. The SPC150480Y8P uses a NEMA 4X enclosure designed for outdoor and harsh environments. It supports external side mounting and is built to withstand dust, moisture, and washdown conditions when properly wired and grounded. For best results, place it in a protected location and follow weatherproof installation practices.
The device is UL 1449 listed, which confirms compliance with recognized safety and performance standards for surge protection devices. This certification supports regulatory qualification, simplifies project documentation, and reduces vendor risk when specifying protection for industrial and commercial facilities.
By limiting transient damage to drives, PLCs, and motors, uptime improves and maintenance costs decline. The 10-year warranty and UL 1449 compliance provide long-term asset protection, reducing replacement costs and unplanned outages. Over the life of the system, this translates to faster production, minimized downtime, and a lower total cost of ownership.
