The Eaton Cutler-Hammer FS340015A is a 15-amp, three-pole circuit breaker designed for use in compatible Eaton/Cutler-Hammer panels. This three-pole device protects three conductors (or a three‑phase circuit) by interrupting fault currents, and the FS340015A part number identifies this exact unit. Use in panels that accept 3-pole breakers to provide reliable overcurrent protection for multi-wire or three-phase circuits.
