Eaton Cutler-Hammer HFD1050 is a Series C molded‑case, single‑pole (1P) circuit breaker rated at 50 A for protecting a single‑phase circuit in commercial or industrial panels. The HFD1050 uses a fixed thermal‑magnetic trip mechanism and is specified for up to 347 VAC and 125 VDC, with an interrupt rating of 100 kAIC at 240 VAC and 65 kAIC at 480 VAC. This 1‑pole device is part of Eaton’s legacy Cutler‑Hammer family (Series C, F‑frame), designed for reliable branch‑circuit protection and compatibility with other HFD family components in compatible panels.
