HFD3090 - 90Amp Circuit Breaker

HFD3090 - 90Amp Circuit Breaker

When you're replacing a circuit breaker in existing equipment, the details matter. The Eaton HFD3090 is a 90-amp, three-pole Series C molded case circuit breaker built around Eaton's HFD F-frame configuration. It is rated for 600 VAC and 250 VDC, operates at 50/60 Hz, and uses the T186 trip type. For fault-current requirements, the HFD3090 carries an interrupt rating of 100 kAIC at 240 VAC and 65 kAIC at 480 VAC. It comes as a complete breaker with load-side terminals and is UL Listed.
