About the CND312T107W

The Eaton CND312T107W is a CND type 1200 Amps/600 Volts AC rated electronic circuit breaker. The CND312T107W supports operation at a 100% rating in an enclosure measuring at least 42 x 22.75 x 11.5 inches in dimensions. The CND312T107W has a weight of 45 pounds and its dimensions are the following: 8.25 inches in width, 8.25 inches in height, and 5.5 inches length. The CND312T107W requires a ventilation space of 0.0258 square meters to the left, 0.0258 square meters to the right, 0.0465 square meters to the top, and 0.0465 square meters to the bottom of the device. The CND312T107W is a 3-pole NG-frame device which does not include terminals. It must be used with supplied conductor extensions and terminal barriers. Only AL9CU or copper terminals and 194 degrees Fahrenheit rated wire are recommended for use with this device. It supports 50 to 60 Hertz of frequency. The following are the interrupt capacity ratings for the CND312T107W: 50 kAIC at 480 Volts AC and 85 kAIC at 240 Volts AC.

The CND312T107W must be installed only after its specifications comply with all the system requirements. Precautions to be following during installation include switching off the breaker and other electrical equipment and clearing the working area of all voltage. The breaker cover constrains the moving breaker parts and it should always be in place during operation. The CND312T107W is provided with an OPTIM 1050 trip unit (LSIA option) which supports advanced features including diagnostics, true RMS sensing, and the monitoring of various breaker parameters, including current and energy.  An overload trip is initiated within 2 hours when a 135% overload occurs, and it is initiated in less time for overloads higher than 135%.
