Eaton Cutler-Hammer EHD1020 1 Pole Circuit Breaker

Eaton Cutler-Hammer EHD1020 is a 1‑pole, 20‑amp circuit breaker designed to protect a single electrical circuit within a distribution panel. As part of the Cutler-Hammer family, model EHD1020 provides standard overcurrent protection by interrupting current during overloads or short circuits. The 1P 20A device safeguards wiring and connected equipment by opening the circuit when current exceeds the 20‑amp rating, helping to prevent overheating and potential damage. This part number identifies a specific unit in Eaton's Cutler-Hammer lineup for use in panels that accept single-pole breakers of this rating. Circuit breakers like the EHD1020 trip under fault conditions to isolate a circuit and reduce the risk of electrical fires. Because it is rated 20A, it is intended for circuits expected to draw up to 20 amperes under normal operation. This specification, EHD1020, helps identify the exact unit when ordering or replacing breakers in Eaton Cutler-Hammer panels.
