Eaton KD3400F Molded Case Circuit Breaker Three Pole

The Eaton KD3400F Molded Case Circuit Breaker, three-pole, serves as a robust overcurrent protection device for electrical power distribution. It is rated for 400 Amps continuous current and supports up to 600 Volts, with a trip setting of 350 Amps to reliably interrupt fault currents before they damage conductors or equipment. The three-pole design ensures simultaneous disconnection of all three phases, which improves fault clearance and reduces the risk of circulating currents in 3‑phase circuits. The unit is housed in a rugged molded enclosure, designed for durability in demanding environments while delivering consistent trip performance. Key specifications include a 400 A rating, 600 V maximum, a 3-pole configuration, and a 350 A trip. The KD3400F designation identifies this model within Eaton’s molded case breaker lineup, making it a recognized option for protecting larger feeders and distribution branches in systems that rely on Eaton protection devices.
