Classifications of Breakers for Solar PV Setups: GFCI, AFCI, and MCCB Differences
During solar array configuration, suitable breaker application promotes reliable and secure operation. The three main breaker types in PV setups include GFCI, AFCI, and MCCB units. Each type serves a distinct purpose and offers various benefits.
GFCIs are designed to detect ground faults, which occur when electricity flows through an unintended path, potentially endangering individuals. 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.
Durable miniature breakers accommodate a range of operational settings. 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.
