Shipping Weight LBS (Approx.): 9
Note: The Remote Aware (RA) option adds a set of NO/NC dry contacts that allow the device's status to be monitored remotely through a supervisory or building management system.
Overview
This Surge Protective Device (SPD) is classified as a primary-level surge protective device intended for service entrances and main distribution panels. It is specifically designed for 3∅ Delta AC Service Types with a Nominal AC Line Voltage (VRMS) of 600 and operates at standard 50/60 Hz frequencies. By installing this unit at the main panel, it establishes the first layer of a robust defense, facilitating cascading protection when combined with secondary units downline.
In plain terms, this high-capacity unit is engineered to isolate critical equipment from both external utility hazards, including large transient events and lightning hazards, and damaging internal surges. With a Total Surge Capacity of 420 kA (at 8x20 µsec pulse) and a Max SE* Surge Current Per Mode/ Per ∅ of 80/160 kA, the SPD effectively diverts massive amounts of harmful energy. It utilizes Single Element SE* Protection Modes in L-L configuration to ensure continuous system integrity. The Remote Aware (RA) option is available, which adds NO/NC dry contacts for remote status monitoring via a supervisory or building management system.
For install fit, the unit is housed in an indoor/outdoor (NEMA 4X) enclosure, signifying dust, drip, hosedown, and corrosion proof capability, with an Enclosure Size (HxWxD) of 8½" x 6¼" x 4¼" (w/¾" mounting knockout size). Installation is designed for flexibility, offering Type 1 & Type 2 Overcurrent Protection with no breaker required, but for fast easy panel installations, a 30 amp breaker can be used - CODE RULE 26-420 (2). The unit comes with 36" #10 AWG Stranded Copper: 3+G leads for connection. Always follow local electrical code and use a qualified electrician where required.
When choosing this model, verify that your system is a 3∅ Delta AC service with a nominal line voltage of 600 VRMS and 50/60 Hz frequency. Key performance metrics include the Max Continuous Operating Voltage (MCOV) of 680 and the UL 1449, 5th Ed VPR Rating of L-L @ 20kA, In: 1800. Protection status is confirmed via the Lifetime Green LED Self Test 'Protection Status Monitors' For Each Phase, and the product is backed by a Manufactures Guarantee - Lifetime Warranty. The device is c-ETL-us Listed and Certified to the latest UL 1449, 5th Edition / CSA C22.2 - no. 269, ensuring compliance and safety standards.
