With a 100 kAIC interrupt rating, SPD100220Y3K delivers robust surge handling for connected loads such as drives and PLCs. It reduces the likelihood of transient-induced faults that trigger costly unplanned downtime. Engineers can quantify protection effectiveness by monitoring the surge events via the built-in counter to support reliability metrics. External sidemount mounting simplifies retrofit into existing distribution equipment and minimizes wiring hours during installation. It keeps service access straightforward by allowing side-entry routes without major panel disassembly. It also enables closer placement to critical loads, improving protection timing and reducing lead length. NEMA 1 enclosure ensures indoor, dust-protected operation suitable for standard electrical rooms, supporting long-term reliability in busy plant environments. The 127/220 V Wye configuration (4W+G) aligns with common commercial power systems and simplifies panel design. Operating voltages of 150 L-N, 150 L-G, 150 N-G, and 300 L-L provide broad compatibility with diverse equipment. This compatibility helps avoid oversizing and enables more predictable protection budgeting. Standard feature package and surge counter give visible status and traceability for audits and preventive maintenance. UL 1449 certification and a 15-year warranty support procurement risk management and lifecycle cost planning. Together these elements reduce maintenance visits and extend equipment life in critical automation environments. Proving sidemounted SPD deployments can deliver measurable efficiency gains and improved uptime across manufacturing and distribution networks.

FAQs
To install SPD100220Y3K, plan a sidemount location on the exterior side of the distribution panel, ensuring adequate clearance for wiring and ventilation. Route conductors to the L-N, L-G, N-G, and L-L terminals, secure the enclosure to its mounting surface, and verify alignment with the panel’s bus arrangement. Use the standard feature package and surge counter to document protection events during commissioning.
SPD100220Y3K is rated for 100 kAIC surge current and supports 127/220 V Wye (4W+G). It operates with voltages 150 V L-N, 150 V L-G, 150 V N-G, and 300 V L-L, covering a broad range of commercial and light-industrial loads while maintaining effective transient suppression.
Yes. Its external sidemount design is specifically intended for retrofit into existing electrical distribution equipment, while the same enclosure and spec sheet apply to new installations. The ease of side mounting reduces retrofitting time, and the UL 1449 certified protection helps ensure regulatory alignment from project kickoff.
SPD100220Y3K carries UL 1449 certification, confirming conformance to surge protection standards. It is housed in a NEMA 1 enclosure and backed by a 15-year warranty, providing long-term protection assurances and improved lifecycle cost planning for mission-critical systems.
The device includes a standard surge counter that logs surge events for maintenance and audits, enabling proactive protection management. The combination of UL 1449 certification and the 15-year warranty reduces lifecycle risk, while 100 kAIC protection helps minimize component replacements and downtime in busy industrial environments.
