The Mid-Circuit Interrupter (MCI) is an essential safety device designed for photovoltaic (PV) systems to provide a reliable method for interrupting DC current within a solar string. Built for high-voltage solar applications, this interrupter enhances system safety by allowing installers and emergency responders to safely disconnect power in the middle of a PV circuit.
Engineered for durability and dependable performance, the 19A, 1000V DC rating makes this unit ideal for residential and commercial solar installations using high-efficiency modules. The compact design allows for seamless integration within PV string wiring while maintaining minimal power consumption at only 7W.
This mid-circuit interrupter helps solar installers meet safety requirements and improve serviceability by providing a convenient disconnection point within the DC circuit. It is commonly used in string-based solar arrays where safe maintenance and emergency shutdown capabilities are required.
