Special features
Basic
Two-module design enables scalable protection and straightforward serviceability, reducing maintenance shutdowns and downtime while allowing easy module replacement in field conditions. This architecture directly supports faster repair cycles and lower total cost of ownership by limiting system exposure and enabling rapid isolation of faulty modules. The 400 kA per phase rating handles high-energy transients typical of industrial sites, protecting downstream equipment such as PLCs, drives, and sensors from damaging surges and short-term faults. Compatibility with 240 delta high-leg (4W+G) systems expands applicability across diverse industrial setups, minimizing retrofit complexities and ensuring reliable operation in legacy configurations. The rugged NEMA 4 enclosure with an internal circuit breaker enhances outdoor and harsh-environment performance, streamlining wiring, mounting, and maintenance access. RoHS compliance and a long warranty (15 years, 20 years with registration) reinforce value, reducing compliance risk and lifecycle costs while supporting regulatory adherence across facilities.
