Standard with surge counter
160 kA per phase surge protection shields critical loads such as motor drives and PLCs from high-energy transients. The business impact is clear: fewer unplanned outages and lower repair costs across conveyors, presses, and packaging lines. In practice, you install this device in a panel feeding heavy equipment, and the protection reacts quickly to spikes, preserving control reliability. 277/480 V Wye (4W+G) compatibility ensures broad applicability in typical industrial power networks, reducing the need for additional transformers or adaptors and shortening install times on new panels or upgrades. This leads to faster commissioning and lower total installed cost for equipment rooms and line side protection. NEMA 4 enclosure with internal terminal breaker provides weather resistance and simplified field wiring, enabling safer outdoor or harsh-environment installations and easier serviceability during routine maintenance or fault investigation. Standard with surge counter delivers real-time visibility into protection performance, supporting proactive maintenance and regulatory reporting, which translates to lower risk of hidden surge damage and improved in-business reliability metrics. RoHS compliance and established certifications (UL, CSA) reinforce regulatory standing and supplier risk management, while the Max series design emphasizes modularity and compatibility with existing protection strategies. Warranty of 15 years (20 years when registered) reduces lifecycle cost and provides a predictable ROI for mission-critical protection in manufacturing, data centers, and utility-grade equipment rooms.

FAQs
The SPM160480Y3T is a single-module SPD designed for 277/480 V Wye systems with a NEMA 4 enclosure and an internal terminal breaker. Mount it inside standard control panels or protected outdoor enclosures, connect the hot phases and ground to the internal terminals, and verify panel ratings align with the 160 kA per-phase capacity. Use the surge counter to monitor performance and schedule periodic checks. Ensure proper torque on terminals and observe clearances for heat dissipation and accessibility during maintenance.
The device provides 160 kA per phase surge protection, suitable for high-energy transients in demanding industrial environments. It includes a built-in surge counter for ongoing protection performance monitoring, helping maintenance teams assess the effectiveness of protection over time and schedule replacements or service before failures occur. The unit is RoHS compliant and UL 1449 listed to ensure reliable performance under standard industry conditions.
Yes, the SPM160480Y3T is well-suited for motor control centers, industrial panels, and data-center peripheral protection where 277/480 V Wye systems prevail. Its 160 kA per phase rating provides strong protection for sensitive drives and controllers, while the NEMA 4 enclosure supports outdoor or harsh environments. The built-in surge counter offers visibility for facility teams, aiding in uptime strategies and compliance reporting.
The SPM160480Y3T carries UL 1449 certification and CSA approvals, along with RoHS compliance. These certifications validate safety and performance for surge protection devices in industrial settings, help meet regulatory and procurement requirements, and simplify acceptance testing in plants. Compliance reduces risk during audits and ensures the device integrates smoothly with other certified components in panel assemblies.
The built-in surge counter enables proactive maintenance by signaling when protection performance is trending downward, reducing unexpected outages. The 15-year warranty (20 years with registration) lowers lifecycle costs and protects invested capital in critical infrastructure. In practice, users experience fewer downtime events, longer equipment life, and improved reliability across manufacturing lines, data centers, and utility-scale protection schemes.
