Eaton GEE3063AFM Molded Case Circuit Breaker MCCB

The Eaton NSB GEE3063AFM is a molded-case circuit breaker (MCCB) configured as a three-pole (3P) protective device rated for 63 A at 480 V. Part of Eaton’s NSB family, the GEE3063AFM is designed to protect distribution circuits in commercial and industrial electrical systems by interrupting excessive current on a three‑phase, 480 V network powered at 50 or 60 Hz. The 3P arrangement protects all three phases of a 3‑phase feeder, making it suitable for uniform 3‑phase loads and panelboard applications that require molded-case protection within 480 V networks. With molded-case construction, this MCCB integrates the switching mechanism, trip protection, and isolation within a compact enclosure to facilitate mounting in standard electrical distribution assemblies. This model designation—GEE3063AFM—identifies the exact configuration within Eaton’s NSB line, providing a reliable, protective device for 3‑phase 480 V circuits across 50/60 Hz installations.
