Eaton HFD3020 - 20 A, 600 V, 3-Pole Circuit Breaker | AmpState

Eaton HFD3020 is a reliable 20A, 600V, 3-pole molded case circuit breaker designed to protect your electrical system with precision. Built for dependable branch circuit overcurrent and short-circuit protection in panelboards and load centers, this device combines compact design with robust performance to keep residential, commercial, and light industrial setups safe and up to code.

What makes this breaker stand out

• Compact molded-case design optimizes panel space, making it easier to fit into tight enclosures and crowded load centers without sacrificing protection.
• Thermal-magnetic trip unit delivers stable, repeatable protection by combining thermal (overload) sensing with magnetic (short-circuit) response for fast, predictable trips.
• OEM-compatible construction is designed to drop into matching Eaton loadcenters and panelboards, reducing installation hassles and ensuring proper coordination with existing equipment.
• 3-pole configuration supports 3-phase circuits and multi-wire branches common in commercial and light industrial applications, while still offering a compact footprint.

Ideal use scenarios

• Residential enhancements and retrofit projects where space in the main or subpanels is at a premium and reliable protection is required for multi-wire circuits.
• Commercial installations protecting feeders to electrical rooms, lighting, HVAC equipment, and small power distribution networks.
• Light industrial environments needing robust overcurrent and short-circuit protection at up to 600V, with a design that fits standard Eaton panelboards.
