Eaton PDG4XPXR30800B2N — 800A Power Defense Trip Unit

Looking for the Eaton PDG4XPXR30800B2N? This is an 800-amp, three-pole electronic trip unit (the part Eaton calls a "Power Xpert Release," or PXR10) that goes inside a Power Defense Frame 4 circuit breaker. In plain terms: it's the brain of the breaker — the piece that decides when to trip if there's too much current. Good to know up front: this is the trip unit by itself, not a whole breaker.

What It's Used For

This trip unit is used in larger electrical systems — think factories, big commercial buildings, and data centers — anywhere an 800A Power Defense Frame 4 breaker needs its protection settings. Because it's a separate part, you can replace or upgrade just the trip unit instead of swapping out the entire breaker.
