Product Introduction

EKDBS-PV4/1-BFS-1000 is a heavy-duty 1000V DC combiner box designed for higher current applications with 4 input strings. This professional-grade unit features advanced MCB protection instead of standard DC isolators, making it ideal for large commercial and utility-scale solar installations where higher output currents are required.

Applications:

EKDBS-PV4/1-BFS-1000 is specifically designed for larger commercial and utility-scale solar installations where multiple high-current strings need to be combined, such as:

Large commercial rooftop solar arrays
Ground-mounted commercial solar fields
Solar carports and canopies
Industrial solar power systems
Small utility-scale solar installations
Applications requiring higher output currents up to 63A

Which DC mini circuit breaker is simplest?

2026/06/11

The simplest DC mini circuit breaker for solar uses non-polarity construction, eliminating orientation errors. Rated up to 125A and 1200V DC with 6kA breaking capacity. Thermal-magnetic protection handles overloads and shorts. Install it either way—it just works.

When Your DC Molded Case Circuit Breaker Keeps Tripping

2026/06/03

A DC Molded Case Circuit Breaker repeatedly tripping signals overload, short circuit, or high ambient temperature. On EKM6DC‑800 models, check for terminal rise >75°C or carbonized arc chamber—both indicate replacement needed.
