Product Introduction

The EKDBS-PV3/1-BFS-600 is an advanced 600V DC combiner box designed to combine three separate PV strings into a single output, providing comprehensive protection for medium-sized solar installations. This professional-grade unit offers complete circuit safeguarding in a spacious IP65-rated enclosure.

Applications:

The EKDBS-PV3/1-BFS-600 is particularly well-suited for medium-sized solar installations where multiple strings need to be combined into a single output, such as:

Commercial rooftop installations with multiple array sections
Residential systems with arrays facing different directions
Agricultural installations with distributed panel locations
Small-scale solar farms requiring string-level protection

What a Type B RCBO Actually Protects Against

2026/07/14

A RCBO (Residual Current Circuit Breaker with Overcurrent protection) combines earth leakage and overcurrent protection in one device. Type B RCBOs detect AC, pulsating DC, and smooth DC faults — critical for PV and EV applications.

Where Is a Breaker with Overcurrent Protection Used Most?

2026/07/01

A breaker with overcurrent protection (RCBO) combines earth leakage and overload protection. Type B detects AC, DC, and high-frequency currents — for EV chargers, solar, heat pumps, and VFDs. Up to 63A, 10kA, 30mA.

Why DC MCCB with IP65 Is the Outdoor Protection You Need

2026/06/26

A DC molded case circuit breaker with IP65 enclosure — dust-tight, waterproof, UV-resistant. Handles 1000V DC, 250A, thermal-magnetic trip, 12kV impulse withstand. Reliable outdoor protection for solar and battery systems.

Which Residual Current Circuit Breaker Fits Your Panel?

2026/06/24

A residual current circuit breaker protects against leakage — electric shock and fire. EKL6-100 offers 16–100A, 30–300mA sensitivity, magnetic tripping, IEC61008-1. Which one fits your panel?
