Panel fit and installation
At 72 mm wide (4 MW), 90 mm tall, and 77 mm deep (70 mm installation depth), this RCBO snaps onto a DIN rail in any mounting position. The IP20 rating applies once the distribution board is installed with conductors connected — so it's a panel-interior device, not a standalone enclosure. Supply can come from top or bottom, which saves a few minutes when you're retrofitting into an existing board and the busbar layout is already set.
Temperature derating — the real-world rating
At 40 °C it derates to 5.3 A, at 45 °C to 5.2 A, at 50 °C to 4.9 A, and at 55 °C to 4.6 A.
Material compliance and approvals
The surge voltage resistance is rated at 4 kV, and it handles a 1 kA surge current (8/20 μs waveform). Compliance documentation (RoHS, REACH, CE) is standard with the brand; the UL/CSA listing is not stated in the evidence, so verify if a North American approval mark is required for your jurisdiction.
