Why it Matters

Matching poles to system voltage
Projoy designed the PEBS-H-125 series for overload and short-circuit protection in high-voltage DC power systems, and describes it as suitable for photovoltaic, energy storage and other DC applications. Its maximum working voltage rises with the number of poles: 250V DC for 1P, 500V DC for 2P, 750V DC for 3P and 1000V DC for 4P. This 2 pole version suits circuits up to 500V DC. Mechanical life exceeds 20,000 cycles, and Projoy lists electrical life for the 80A rating at more than 300 cycles.

Certified for Australian supply
SAA Approvals Pty Ltd issued certificate SAA-241018-EA to ProJoy Electric Co., Ltd. for model PEBS-H-125, to AS/NZS IEC 60947.2:2015. The certificate lists DC500V for 2P, rated currents of 80, 100 and 125A, Icu 6kA and Ics 6kA. It was issued on 25 July 2024 and expires on 25 July 2029.

Switchboard fit and wiring
The breaker clips onto 35mm DIN rail. Projoy lists the 2P at 54mm wide, 89mm long and 75.5mm high, weighing 0.17kg per pole. For the 80A rating, Projoy's harness specification lists 25mm² (4 AWG) copper conductors tightened to 3.5Nm. The front is IP40 and the wiring ports are IP20.

Q: Is the Projoy PEBS-H-125 80A 2 pole DC MCB SAA certified?
A: Yes. Model PEBS-H-125 is covered by SAA certificate SAA-241018-EA to AS/NZS IEC 60947.2:2015, which lists the 2 pole DC500V rating and rated currents of 80, 100 and 125A.

Q: What is the maximum DC voltage of the PEBS-H-125 2 pole breaker?
A: The 2 pole version has a maximum working voltage of 500V DC. The 3 pole and 4 pole versions of the series are rated 750V DC and 1000V DC.

Q: What cable size suits the 80A PEBS-H-125?
A: Projoy's harness specification lists 25mm² (4 AWG) copper conductors for 80A, tightened to 3.5Nm. The terminals accept conductors from 6 to 50mm².
