EKM7DC is a solar photovoltaic-specific molded case circuit breaker developed by ETEK Electric, compliant with the IEC 60947-2 standard. It features a rated working voltage of up to DC1500V, a rated insulation voltage of 1500V, a rated impulse withstand voltage of 12kV, and a rated current range of 100A to 1600A. These circuit-breakers are capable of breaking short-circuit currents up to 20kA in 1500V DC voltage applications.

Widely used in the main circuits of combiner boxes, DC cabinets, and inverter cabinets, the EKM7DC provides short-circuit protection, overload protection, and isolation functions. This helps prevent system failures caused by current from other circuits passing through short-circuit points. Its compact size, easy installation, safety, reliable operation, and high cost-effectiveness make it well-suited for the needs of photovoltaic power generation.
