GEESYS DC Distribution Board-18in18out(fuse-mcb-mov)mc4 is an electrical panel used to distribute direct current (DC) electricity to various circuits. It's commonly used in solar power systems, battery storage systems, and other applications that use DC power.This likely refers to the configuration of the distribution board, with 18 input terminals and 18 output terminals. This means the board can handle 18 separate DC input sources and distribute power to 8 different output circuits.A fuse is a safety device designed to protect electrical circuits by breaking the circuit if the current flow exceeds a certain level. This helps prevent damage to equipment and reduce the risk of fire.The MCB (Miniature Circuit Breaker) is a switch that automatically switches off to protect the circuit when there is an overload or short circuit. It can be reset after it trips, unlike a fuse, which needs to be replaced.The MOV (Metal Oxide Varistor) is a component used to protect electrical equipment from voltage surges and spikes. It absorbs excess voltage and helps prevent damage to the system.MC4 is a type of connector commonly used in solar photovoltaic systems. It ensures a secure and waterproof connection between solar panels and other components of the solar power system.GEESYS DC distribution board with these specifications is designed to safely distribute DC power, protect against overloads and surges, and facilitate connections, particularly in solar power systems or other DC applications.
