About the HND312T107W

The HND312T107W circuit breaker is a series C molded case circuit breaker designed and manufactured by Eaton. The circuit breaker has a type N frame size. The HND312T107W circuit breaker is HACR rated and listed by the Underwriters Laboratories (UL). The circuit breaker measures 8.25 inches in height, 8.25 inches in width, and 5.5 inches in depth. The HND312T107W circuit breaker weighs 48 pounds. The circuit breaker has a voltage rating of 600 Volts AC, a current rating of 1200 Amps, and an electronic LSIA trip type. Additionally, the circuit breaker has 3 poles. The Eaton HND312T107W circuit breaker, like other circuit breakers with an N-type frame size, has an integral trip unit and interchangeable rating plugs. Also, circuit breakers with this frame size satisfy the requirements of the International Electrotechnical Commission (IEC). 

When installing the HND312T107W circuit breaker or another Eaton circuit breaker, ensure that it can accommodate the requirements of the intended application. This can be determined by comparing the circuit breaker’s nameplate data with the application’s ratings and requirements. For the trip settings, note that the HND312T107W circuit breaker, like other series C N-frame circuit breakers, has its trip unit builtin as an integral part of the breaker. As such, it cannot be replaced in the field. Additionally, during installation, the HND312T107W circuit breaker requires the installation of a rating plug which establishes the maximum continuous current rating of the circuit breaker. Note that before attempting to install the rating plug, the arrow in the push-to-trip button portion of the plug must be pointed in the “remove” position. This can be done with the help of a small screwdriver.
