Eaton Cutler Hammer NDC3800T33W 800A 3-Pole Molded Case Circuit Breaker – LS Trip Unit – Bolt-On – 600VAC

The Eaton / Cutler Hammer NDC3800T33W is a high-capacity 800 Amp, 3-pole molded case circuit breaker engineered for reliable protection in demanding industrial and commercial electrical distribution systems. Built on the NDC frame platform, this breaker features a Digitrip RMS 310 electronic non-interchangeable trip unit with LS (Long Delay, Short Delay) protection functions. Its current-limiting design and ultra-high interrupting capacity provide enhanced protection against overloads and short circuits while minimizing the effects of high fault currents on downstream equipment.
