Arc Flash Label Calculator vs Kopperfield

An easy to use develop arc flash label calculator and label generator. Input the necessary information into the app and it will generate a PDF label using NFPA 70E Annex D.4 (VAC) arc flash label calculations & methodology. Support for circuit breakers: MCCB, ICCB & LSI (Electronic LVPCB) and fuses by Cooper Bussmann and Ferraz-Shawmut including Classes: RK1, RK5, L, J, CC, T & H. Wide support for different overcurrent protection devices and pre-programmed models are setup for easy use. Custom configurations are supported by adjustments conductor gap, working distance and arcing time. Arc flash label calculates and includes: Incident Energy [cal/cm^2], Arc Flash Boundary, Limited Approach Boundary, Restricted Approach Boundary, Hazard Risk Category, voltage and short circuit current. Labels output 4 per sheet using standard 4 label template. Develop arc flash labels for low, medium and high voltage three phase equipment up to 15,000VAC and 1,000VDC. High voltage package required for voltages over 220V. Quick preset options to support major international standards. Requires Mail app configured for outgoing email.
