The SP1-480Y uses a three-phase design to deliver up to 50 kAIC surge protection, directly reducing the risk of equipment damage during voltage transients. This translates to fewer unplanned outages, lower maintenance costs, and longer asset life in critical automation lines. Its compact footprint—2.5 in deep, 4.8 in tall, and 2.9 in wide, weighing 1.25 lb—facilitates installation in crowded control panels and standard electrical enclosures, speeding commissioning. The UL 1449 certification provides safety confidence across industrial environments, supporting compliance with margin requirements in regulated facilities. A 2-year warranty further lowers lifecycle costs and supplier risk for OEMs and panel builders. With a clear catalog identity (SP1-480Y) and UPC, procurement is straightforward, improving lead times for spare parts and replacements. The device is designed to work within the SP1 family ecosystem, enabling scalable protection across multi-panel deployments and simplifying maintenance workflows.
