1250 A amperage rating paired with a 600 Vdc maximum and 65 kAIC interrupt capability delivers robust protection for heavy DC feeds. The business impact is clear: fewer nuisance trips and faster fault clearance translate into higher machine uptime and safer operation in drives, battery systems, and process lines. In practice, this means your control panels stay online longer, reducing unplanned downtime and maintenance costs. An electronic T174 trip type provides precise, fast protection logic and selective coordination, helping avoid cascading trips in multi-circuit panels and improving isolate-and-repair cycles after events. Three-pole construction with terminals indicated as without terminals offers flexibility; pair with compatible multi-wire terminals to tailor terminations and simplify installation. UL Listed, IEC Rated, and CSA Certified support global compliance for equipment in North America and abroad; Series G design aligns with industry standards and prevents rework during audits. Series G MCCB is designed for control panels and industrial enclosures; its modular footprint and documented installation guidelines help integrators meet space constraints and mounting requirements, delivering reliable protection with fewer field issues.
