The NF-C Series is the economy class of molded case circuit breakers from MITSUBISHI ELECTRIC, covering standard distribution and control panel duty at a lower cost than higher breaking-capacity models. A thermal-magnetic trip unit opens the circuit on overload or short circuit, and the breaker doubles as a manual switch for isolating loads. It is used in lighting, power distribution and equipment feeder circuits.
