FAQs
Yes. The SPM200480Y4T is rated for 277/480 V Wye with four conductors plus ground (4W+G), making it suitable for typical industrial distribution panels and switchgear. The internal terminal block simplifies wiring, speeds installation, and reduces the risk of field wiring errors. Ensure proper clearance and mounting as per the specification sheet during integration.
The device delivers 200 kA per phase surge protection, providing a high-capacity barrier against transient overvoltages caused by switching events or external faults. This high rating helps prevent damage to sensitive equipment like PLCs, drives, and servers, reducing downtime and extending equipment life in demanding environments such as data centers and manufacturing floors.
Ideal for critical electrical distribution in data centers, processing plants, and manufacturing lines, especially where 277/480 VAC distribution is common. The NEMA 4 enclosure supports indoor and protected outdoor installations, while UL 1449 certification provides regulatory confidence. Use with Power Xpert systems for coordinated protection across a facility’s SPD network.
The SPM200480Y4T is UL 1449 listed, ensuring compliance with a widely recognized safety standard for surge protective devices. It features a durable NEMA 4 enclosure for moisture and dust resistance and is compatible with four-wire plus ground configurations. These certifications and ratings support safety, reliability, and regulatory alignment across industrial facilities.
Installation efficiency, due to the internal terminal block and straightforward wiring, reduces commissioning time and labor costs. The high surge rating lowers the likelihood of device or equipment failures, cutting unplanned downtime. Over time, improved reliability translates to lower maintenance expenses and a shorter path to ROI, especially in environments with frequent transient events.
