FAQs
The SPM160240S4R is designed for standard 120/240V split-phase panels with a NEMA 4 enclosure and an internal circuit breaker, simplifying wiring and reducing external devices. Plan mounting space for its 9.5 in length, 15 in width, and 17.05 in height, and account for a 52 lb weight. Ensure clearance for service access and proper grounding per electrical codes.
This device provides 160kA per phase surge capability, delivering robust transient protection for each phase in split-phase systems. This rating helps prevent overvoltage events from propagating to sensitive equipment, reducing the risk of insulation damage, data errors, and unexpected outages in critical loads such as servers and PLCs.
Yes. The SPM160240S4R supports integration with Power Xpert SPD, enabling centralized monitoring and diagnostics. This compatibility allows proactive protection management, alarms, and maintenance scheduling, which can shorten downtime and optimize asset lifecycle costs.
The unit features a NEMA 4 enclosure, which provides protection against dust, water ingress, and other harsh conditions. While suitable for limited outdoor installations, ensure enclosure integrity and mounting, and follow local codes for exposure and drainage to maximize long-term reliability.
By guarding critical loads and reducing surge-related failures, the SPM160240S4R can lower downtime costs and extend equipment life. With UL 1449 compliance and optional Power Xpert monitoring, maintenance cycles become more predictable, enabling better asset management and a clearer, data-driven ROI over facility lifetime.
