DC string protection circuit breaker with 2-pole switching and 12 A rated current for photovoltaic systems up to 1000 V DC. Thermal-magnetic trip unit with adjustable overload protection from 8 A to 12 A and fixed short-circuit release. Breaking capacity 10 kA at 1000 V DC. Mounts on DIN rail EN 60715, screw terminals accept conductors up to 25 mm².

Advantages

High DC voltage rating for modern PV strings. Adjustable overload setting matches array current precisely. Compact DIN rail design saves space in combiner boxes.

Suitable for

  • Protecting PV strings in solar installations
  • DC-side overcurrent and short-circuit protection
  • Use in combiner boxes and inverter DC inputs

Key specifications

  • Rated operational voltage: 1000 V DC
  • Rated operational current: 12 A
  • Overload release setting range: 8–12 A
  • Short-circuit breaking capacity: 10 kA at 1000 V DC
  • Degree of protection: IP20 (terminals)
  • Connection: screw terminals, 1 x (1–25 mm²) or 2 x (1–10 mm²)
  • Operating temperature: -25 °C to +70 °C

Recommendations

Select the overload setting closest to the PV string's maximum current. Ensure the short-circuit current of the array does not exceed 10 kA. Use appropriate DC-rated wiring and torque terminals per manufacturer instructions.
