Breakers and Fuses
The types of specialty breakers that we sell are designed and rated especially for renewable energy. The kind of breakers that you can get locally are not DC rated (Or legal) for use in your RE system.
Some of the Square D QO breakers are AC/DC rated but on the DC side they are only rated to 48 volts, which means they theoretically could be used in 12 or 24 volt systems but, all the voltage in a 48 volt system are above 48 volts so they cannot be used. The same thing holds true for automotive and marine breakers and fuses as well.
With charge controller voltages at 150, 250 and 600 volts DC, special breakers and fuses designed for the purpose are code compliant and are a must. The DC Breakers we carry are rated at 125, 150 and 300 volts DC and touch safe fuses and holders are rated for 600 volts DC. Each rating is for a particular purpose, ask your sales person for the correct part for your application.Call our toll free number 888-826-0939 if you have any questions about the Fuses and Breakers
