Special features
Standard with surge counter
Max series surge protection devices deliver high surge current handling in a compact, single-module form. This translates to reduced downstream damage when events reach 400 kA per phase, protecting sensitive electronics and motor drives in busy panels and switchgear. Ideal applications include industrial control panels where space is at a premium and reliability is non negotiable. Configured for 120/208 V Wye networks (4W+G) and housed in a NEMA 4X enclosure with an internal terminal block, the SPM400208Y3X is built for tough environments. The robust enclosure and simple wiring reduce installation time and field errors, while maintaining safe, compliant operation in outdoor or washdown areas. Standard with a surge counter, the device provides visibility into surge events, supporting maintenance scheduling and asset management. This reduces unexpected downtime by enabling data-driven decisions. Warranty coverage adds lifecycle value: 15 years from delivery, or 20 years with online registration, lowering total cost of ownership and risk of premature replacement. Compliance and compatibility are straightforward with RoHS, UL 1449, UL 1283, and CSA C22.2 No. 8 ratings, ensuring design-in across OEMs and facilities. The internal terminal block simplifies wiring, while the 9.3 in L x 14.91 in W x 17.5 in H footprint fits standard electrical panels.

FAQs
Install the SPM400208Y3X in the main or downstream electrical panel using the internal terminal block for wiring. Ensure the panel rating matches 120/208 V Wye (4W+G), secure the NEMA 4X enclosure in a suitable location, and follow manufacturer torque specs for all connections. The unit’s 9.3 in L, 14.91 in W, and 17.5 in H footprint fits standard enclosures and minimizes layout changes.
Yes. The device is explicitly rated for 120/208 V Wye systems with four insulated conductors plus a ground (4W+G), making it suitable for control panels and downstream circuits in typical commercial and industrial environments.
The unit carries UL 1449 and UL 1283 certifications, and CSA C22.2 No. 8-M1986, with RoHS compliance. These certifications support safe operation, electrical noise suppression, and regulatory acceptance across North American facilities.
A built-in surge counter provides visibility into surge events, enabling proactive maintenance planning and trend analysis. The 15-year warranty (20 years with online registration) also reduces maintenance risk and replacement costs over the asset’s lifecycle.
The surge protection reduces downstream equipment damage, cutting repair costs and downtime. With a long warranty, RoHS compliance, and a simple installation in 120/208 V systems, facilities gain predictable protection for control electronics and drives, improving uptime and extending asset life, delivering meaningful total cost of ownership benefits.
