50 kA surge protection rating provides robust defense against high-energy transients, limiting voltage overshoot and protecting downstream devices. This translates to fewer drive failures, lower maintenance costs, and reduced downtime across 480V delta networks used in motor drives and automated lines. The UL 1449 certification and UL1283 5th Edition filtering deliver compliance and EMI suppression, improving signal integrity for PLCs and HMIs while reducing troubleshooting time. The NEMA 4X enclosure and external side mounting offer rugged installation options for outdoor or washdown environments, enabling faster deployment and long-term durability in harsh factories. A 10-year warranty supports total cost of ownership objectives, helping maintenance teams plan budgets confidently and minimize unexpected replacement expenses. The compact footprint (5.5 in depth, 6 in height, 3.19 in width) and a 2.5 lb weight simplify integration into crowded control cabinets and distribution panels while preserving cabinet space for future expansion.

FAQs
The SPC050480D2P uses an external side mounting method and is designed for 480V delta networks. Ensure the device is secured to a suitable panel backplane or enclosure with appropriate clearances. Verify the NEMA 4X enclosure remains intact to maintain environmental protection. Use proper torque on terminals and follow the manufacturer's wiring diagram to connect line, load, and ground correctly for optimal protection.
This model delivers up to 50 kA per phase of surge protection with UL 1449 certification. It also features UL1283 5th Edition filtering to suppress EMI/RFI, helping maintain signal integrity in sensitive control circuits. These specs translate to improved equipment uptime and reduced EMI-related anomalies in typical industrial environments.
Yes. The 50 kA rating and 480V delta compatibility make it well suited for motor drives and PLC panels, where transient events can propagate along power lines and disrupt control logic. The NEMA 4X enclosure protects against dust, water, and washdown environments, while the external-side mounting simplifies integration into existing setups without major retrofits.
The SPC050480D2P is UL 1449 certified for surge protection performance and safety, and it incorporates UL1283 5th Edition filtering for EMI suppression. It uses a NEMA 4X enclosure rating to resist moisture and dust in challenging environments. These certifications support compliance in regulated facilities and enhance reliability claims for auditing teams.
The unit carries a 10-year warranty, reflecting confidence in long-term performance and lower lifecycle costs. Maintenance considerations center on periodic inspection of connections and enclosure integrity, with typical replacement intervals driven by surge exposure. The device’s reliability and EMI protection help minimize downtime, reduce spare parts consumption, and improve overall return on investment in critical automation systems.
