The Eaton HKD3175 is a 3-pole, 175A, 600V, 35kA molded-case circuit breaker in Eaton's HKD frame. As an MCCB, it is designed for installation in commercial and industrial panelboards and switchboards that accept HKD-frame bolt-on breakers — not residential loadcentres. Typical applications include motor branch-circuit protection, feeder protection, and distribution panels operating at up to 600V AC.
Frame compatibility depends on the specific panelboard or switchboard make and model. Send us your panelboard model and we'll confirm fitment.
Yes — the HKD3175 carries a 35kA interrupt rating at 600V, making it well suited for commercial and light-industrial distribution systems where higher fault currents are present. Always verify your available fault current (AFC) at the point of installation to ensure the breaker's 35kA AIC meets or exceeds your system's requirements.
The Eaton HKD frame is an established MCCB series, but specific ampere ratings and configurations can become difficult to source, particularly for older or legacy installations. Northern Breaker Group specialises in obsolete and hard-to-find breakers — contact our Calgary, Edmonton, or Vancouver counter for current availability and lead times.
In most cases, yes — provided the replacement matches the original breaker's frame (HKD), pole count (3P), ampere rating (175A), voltage rating (600V), and interrupt rating (35kA), and the panelboard is rated to accept it. Always consult a licensed electrician and verify the panelboard manufacturer's approved breaker list before completing any replacement.
