Why it Matters

Certified for the Australian market
SAA Approvals has issued certificate SAA-191046-EA to Projoy for the PEBS-H DC miniature circuit breaker against AS/NZS IEC 60947.2:2015. The certified ratings cover this unit: 2 pole at 500V DC, 63A rated current, Icu and Ics of 6kA, and C-type instantaneous tripping at 8In. The certificate runs to 2 May 2029.

Made for DC power systems
Projoy designs the PEBS-H-63 series for high-voltage DC systems and lists photovoltaic, energy storage and battery pack applications. The series runs from 1 to 4 poles, with the working voltage stepping up per pole: 250V DC (1P), 500V DC (2P), 750V DC (3P) and 1000V DC (4P). Projoy's contact configuration diagrams show two ways to wire the 2P: both poles in series on one conductor, or one pole in each conductor.

Sizing and installation
For the 63A rating, Projoy's harness table specifies 16mm² copper (it also lists 6 AWG) at 2.0-2.5 N·m. The body measures 36mm max wide, 87.5mm high (91mm max) and 81mm max deep. Rated current is referenced at 30°C. Projoy publishes temperature reduction coefficients across the ambient range, plus altitude reduction coefficients above 2000m. Projoy also offers MX shunt trip and OF auxiliary contact accessories for PEBS-H (not included).

Q: Is the Projoy PEBS-H-63 63A 2 pole DC MCB SAA certified?
A: Yes. Its model, PEBS-H, is listed on SAA certificate SAA-191046-EA, issued by SAA Approvals against AS/NZS IEC 60947.2:2015. The listed ratings include 2 pole at 500V DC, 63A and 6kA.

Q: What cable size does the PEBS-H-63 63A breaker take?
A: Projoy specifies 16mm² copper for the 63A rating (its harness table also lists 6 AWG), tightened to 2.0-2.5 N·m. The terminals accept 2.5mm² to 35mm² conductors.

Q: Does the 63A rating change in a hot switchboard?
A: Yes. The 63A rating applies at 30°C. Projoy's coefficient is 0.968 at 40°C (about 61A) and 0.844 at 70°C (about 53A), the top of the -30°C to +70°C ambient range.
