Special features
Standard with surge counter
High-amp protection with a 120 kA per phase surge rating ensures robust defense against damaging transients, reducing motor/drive stress and equipment downtime. This translates to improved uptime and longer service life for critical assets in manufacturing, water treatment, and process facilities. The 120/240 V split-phase design aligns with common U.S. electrical distributions, enabling straightforward deployment across feeders and panelboards while preserving optimal phase-to-phase protection. A rugged NEMA 4 enclosure with an internal terminal breaker simplifies installation in damp, dusty, or outdoor locations, consolidating protection and disconnect functionality in a single, weather-resistant module. Standard with a surge counter provides immediate visibility into surge activity, supporting maintenance planning, regulatory reporting, and trend analyses for asset health. Certifications and compliance—RoHS, UL 1449, UL 1283, CSA listings—minimize procurement risk and facilitate audits in regulated sectors such as data centers, food and beverage, and utilities. Dimensions and weight (9.3 in depth, 14.91 in width, 17.5 in height, 50 lb) support precise space planning and mounting in standard electrical rooms, while compatibility with common rack layouts speeds up installation and reduces field labor.
