The ETNFD2100 is an Eaton 2 Pole 100 Amp 600V Circuit Breaker, designed for reliable performance in both residential and commercial electrical systems. This robust breaker offers efficient overload and short circuit protection, ensuring the safety of your electrical installations. Compact and easy to install, it’s an excellent choice for circuit management.
The Eaton FD frame is a molded-case circuit breaker (MCCB) series rated up to 600 V AC, designed for commercial and industrial panelboards and switchboards. Unlike the BR or CH plug-in residential breakers, FD-frame breakers are bolt-in devices built for heavier-duty applications with higher interrupting ratings, making them unsuitable for standard residential loadcentres.
Yes — Northern Breaker Group specializes in obsolete and hard-to-find breakers, and the Eaton FD frame has a long production history, making cross-compatibility with older Eaton (and legacy Cutler-Hammer) FD-frame panelboards very common. Contact us with your existing panel model number and we'll verify the fit.
Yes. A 600 V-rated breaker can be applied on lower-voltage systems such as 120/240 V or 347/600 V — the voltage rating is a maximum, not a fixed operating point. The 100 A, 2-pole configuration makes it well suited for feeder or branch circuit protection on standard Canadian 120/240 V or 347/600 V distribution systems. Always verify the interrupting rating meets your system's available fault current.
