The 4P, 400 A rated configuration provides scalable protection for medium to high power feeders, reducing nuisance trips while enabling straightforward wiring in compact control panels. This directly translates to shorter commissioning times and improved reliability in factory automation environments, where every connection must be secure and accessible. Its front-terminal design enables quick, maintenance-friendly installations, cutting wiring errors and service downtime during upgrades or repairs. The unit supports high short-circuit withstand and insulation ratings (U i 1000 V, U imp 8 kV), which protects downstream equipment and sustains uptime in transformer and motor circuits. And with durable electrical and mechanical life (up to 7000 electrical cycles and 20000 mechanical cycles), owners benefit from lower maintenance costs and longer intervals between replacements. Compliance features including REACH, RoHS, CMRT, TSCA, and CE/IEC declarations simplify procurement and regulatory reporting. The Tmax T5 family compatibility (Release PR221DS-LS/I) ensures consistent protection schemes across panels and enables standardization across multiple sites, reducing spare parts complexity and stocking needs. Keithly-focused field technicians will appreciate the measured balance of rugged protection and installation ease, which translates to faster project realization and predictable lifecycle costs.
