Eaton HFD3020L - 20 A, 600 V, 3-Pole Circuit Breaker | AmpState

The Eaton HFD3020L is a 3-pole molded case circuit breaker designed to deliver reliable branch circuit overcurrent and short-circuit protection in panelboards and loadcenters. With a 20A rating and a 600V insulation capability, it’s built to handle demanding electrical environments while keeping your power distribution clean and safe.

Why engineers and electricians choose the HFD3020L:

• Compact molded case design maximizes panel space and simplifies installation in tight electrical enclosures, making it ideal for retrofit projects or crowded panelboards.
• Thermal-magnetic trip unit provides stable, repeatable protection by responding to both overloads (thermal) and short circuits (magnetic), reducing nuisance trips and ensuring quick isolation when faults occur.
• Three-pole (3P) operation offers coordinated protection for three-phase circuits with a common trip, ensuring simultaneous disengagement of all poles for safer motor and equipment protection.
• OEM compatibility designed to pair with matching Eaton OEM loadcenters and panelboards, ensuring a seamless fit and reliable performance in standard configurations.
• Versatile applications suitable for residential, commercial, and light industrial environments, from small business electrical closets to equipment rooms with 3-phase loads.
