The breaker is sealable, rated IP20 with conductors connected, and can be mounted in any orientation – no derating needed for vertical vs. horizontal unless you're pushing ambient temp above 40 °C (see the humidity/temperature derating: 95% RH up to 55 °C, then restrict to 35% RH at 75 °C). Pollution degree 3, overvoltage category III. The quick-assembly system and halogen-free, silicon-free construction are standard for the SENTRON line.
