Eaton HFD1020 Bolt-On Circuit Breaker

Eaton HFD1020 Bolt-On Circuit Breaker is a 1-pole, 1-phase overcurrent protection device rated at 20 A for 277 V. This bolt-on model is designed for direct mounting in compatible panels, providing reliable protection for a single hot conductor in 277-volt circuits. The HFD1020 designation identifies a 20 A, 277 V, 1P/bolt-on breaker within Eaton's HFD family, enabling straightforward replacement in Eaton-compatible electrical panels. Because mounting is bolt-on, installation involves securing the breaker to the panel with fasteners, ensuring a solid electrical and mechanical connection. Verify panel compatibility and follow local electrical codes during installation to ensure proper fit and safe operation. Typical applications involve protecting branches in electrical distribution systems that use 277 V as the supply, where a single-pole interrupt is sufficient for the protected circuit. Choosing a bolt-on breaker like the HFD1020 can simplify retrofits in panels configured for Eaton's HFD series, as it matches the form factor and electrical characteristics of existing breakers.
