Eaton FS340070A 3 Pole 480V AC Circuit Breaker

The Eaton FS340070A is a three-pole, 480V AC circuit breaker from the Cutler-Hammer family, with a 70 A rating. This protection device guards three-phase electrical circuits in 480 VAC distribution mains by interrupting current when an overcurrent or fault is detected, helping prevent damage to wiring, motors, and connected equipment. With its three-pole configuration, all three phases are simultaneously interrupted, supporting balanced protection in standard 480V three-phase installations. The FS340070A is suitable for use in industrial environments where 480V three-phase power is present, including panelboards, switchgear assemblies, and feeder circuits, providing a straightforward means to isolate a fault condition and maintain system safety. Users specify electrical protection by selecting the FS340070A's 70 A rating within a 480 VAC system, aligning with common protection practices for medium- to large-current motor and line circuits in commercial and industrial settings.
