Feature → Business Impact → Application: 400 A amperage rating enables full-load protection for demanding loads in panel boards and MCCs, reducing nuisance trips and safeguarding equipment. This translates to improved uptime and predictable maintenance costs in manufacturing and process facilities. Application: Use in motor control centers and distribution panels requiring high interrupt capability and reliable protection under mixed AC/DC loads. Feature → Business Impact → Application: 600 Vac / 250 Vdc voltage ratings extend protection across standard industrial power domains, supporting both AC mains and DC control circuits for conveyors, pumps, and drives. Application: Ideal for mixed-voltage environments where a single MCCB addresses both power and control circuits. Feature → Business Impact → Application: KD frame with a three-pole configuration delivers a compact, adaptable form factor that fits standard switchgear footprints, simplifying retrofits and new installations. Application: Suitable for panel retrofit projects and new builds in automation lines. Feature → Business Impact → Application: Trip Type T165 and 65 kAIC at 240 Vac / 35 kAIC at 480 Vac provide precise coordination with upstream protection devices, minimizing arc exposure and improving fault clearance times. Application: Critical for safety-conscious facilities with heavy motor loads. Feature → Business Impact → Application: 110-127 Vac undervoltage release and 1A-1B rear right pigtail/left pigtail terminals enable integrated control circuits and remote signaling, reducing wiring complexity. Application: Useful in safety interlock schemes and automated control panels. Feature → Business Impact → Application: TA350K terminal catalog note ensures compatibility with existing lugs and terminal hardware, accelerating procurement and reducing engineering time. Application: Streamlined sourcing for maintenance teams working across multiple Eaton MCCB platforms.
