HFD3070 - 70Amp Circuit Breaker

HFD3070 - 70Amp Circuit Breaker

When your existing electrical system calls for an Eaton HFD3070, matching the full breaker specification matters. This 70-amp, three-pole molded case circuit breaker is part of Eaton’s Series C HFD family and uses an F-frame complete-breaker configuration. It is rated for 600 VAC and 250 VDC, operates at 50/60 Hz, and uses a T186 trip type. The HFD3070 carries interrupt ratings of 100 kAIC at 240 VAC and 65 kAIC at 480 VAC, while the specified terminal arrangement is load side. If the existing application requires this combination of Series C, HFD type, F frame, amperage, poles, voltage, trip type, interrupt ratings, and terminal configuration, the HFD3070 provides the intended form, fit, and function. It’s built to last when correctly installed and operated within its published ratings.
