Panel & Switchboard Compatibility

The Eaton HFD1020 is a molded case circuit breaker (MCCB) in Eaton's HFD frame, rated 1-pole, 20A, 347V AC, 25kA interrupt capacity, with a bolt-on mounting configuration. As an MCCB, it is designed for installation in commercial and industrial panelboards and switchboards that accept HFD-frame bolt-on breakers — not for use in residential loadcentres. It is well-suited for 347V single-phase branch circuit protection common in Canadian commercial lighting and HVAC applications.

Specific panelboard compatibility depends on the enclosure's bus configuration and frame acceptance. Send us your panelboard model and we'll confirm fit.

Canada's commercial electrical systems commonly use 347/600V distribution, particularly for lighting circuits. The HFD1020 is specifically rated for 347V AC at 1 pole, making it a code-compliant choice for 347V branch circuit protection in commercial and industrial facilities — a rating not found on standard residential breakers.

Availability of specific HFD-frame breakers can vary. Northern Breaker Group specializes in obsolete and hard-to-find breakers, so even if the HFD1020 has been superseded or is no longer in regular distribution, we can often source new-old-stock or compatible replacements. Contact our Calgary, Edmonton, or Vancouver counter for a quote.

The HFD1020 carries a 25kA symmetrical interrupt rating at 347V. For most commercial branch circuit applications this is adequate, but you should verify the available fault current at the point of installation with your engineer or authority having jurisdiction (AHJ). If a higher interrupt rating is required, Eaton's HFD frame is available in other interrupt ratings — reach out and we can help identify the right option.
