Classifications of Breakers for Solar PV Setups: GFCI, AFCI, and MCCB Differences
In photovoltaic installations, breaker choice critically affects operational security and output. There are three primary types of circuit breakers commonly used in solar PV installations: Ground Fault Circuit Interrupter (GFCI), Arc Fault Circuit Interrupter (AFCI), and Miniature Circuit Breaker (MCCB). Each classification handles unique issues and presents specific benefits.
Ground fault interrupters cut power flow when unexpected grounding paths are present, securing persons. They provide rapid disconnection in the event of a fault, minimizing the risk of electric shock. AFCIs, on the other hand, are specialized breakers that identify and interrupt dangerous arcing conditions. Arcing can result from damaged wiring or faulty electrical connections, posing a fire hazard.
Compact MCCBs handle diverse currents with dependable strength. They are typically used to protect against overcurrents and short circuits in higher-power applications. MCCBs often feature adjustable current settings and offer additional protection mechanisms such as overload protection and thermal trip characteristics.
