Why ReneWave may shortlist it
- SM8-250HPV/2 molded-case DC breaker: 250 A frame, 250 A rated current, two poles at 1000 V DC. Overload and instantaneous short-circuit protection; no C-curve rating is claimed.
System position
DC overcurrent protection: conceptual single-line view.
Use the documented two-pole power/load connection, one pole on each DC conductor. Follow terminal orientation and upstream/downstream placement; reverse-polarity operation is not asserted. PE remains outside the switched path. DC overload and short-circuit interruption within the documented connection and capacity. No residual-current or surge protection is provided. The 250 A frame is not the selected trip current; neither AC ratings nor other SM8 pole arrangements apply.
The DC source supplies the conversion equipment through the closed protection path. Protective earth remains connected outside the interruption path.

03 · Selection points
Four practical selection points.
Match the circuit, device function and documented limits.
- 01
DC circuit and connections
Use the documented two-pole power/load connection, one pole on each DC conductor. Follow terminal orientation and upstream/downstream placement; reverse-polarity operation is not asserted. PE remains outside the switched path.
- 02
Current and voltage
SM8-250HPV/2 molded-case DC breaker: 250 A frame, 250 A rated current, two poles at 1000 V DC. Overload and instantaneous short-circuit protection; no C-curve rating is claimed.
- 03
Protection coordination
Icu 20 kA and Ics 15 kA (75% of Icu) at 1000 V DC, for SM8-250HPV/2 only. The 2020.01.V2 manual’s two-pole column governs; do not use the three- or four-pole headline capacities. DC overload and short-circuit interruption within the documented connection and capacity. No residual-current or surge protection is provided. The 250 A frame is not the selected trip current; neither AC ratings nor other SM8 pole arrangements apply.
- 04
Mounting and connections
Fixed mounting: M4 × 55 screws and the two-pole installation drawing. Maintain the documented 80 mm arcing clearance. Terminal hardware and any DIN adapter are not asserted as included.
