The 16 A rated current at 230 V AC is the continuous load it can carry without tripping under normal conditions. The 1P+N pole configuration switches the line conductor and provides a switched neutral — the neutral is opened and closed with the line, not just solidly connected. This matters where you need isolation of both poles for maintenance or where local code demands a switched neutral on single-phase final circuits. The single width unit means it occupies 18 mm of DIN-rail space, so it fits a standard 18 mm-per-pole panel layout.
Panel integration and environment
Degree of pollution 2 and overvoltage category III confirm it is rated for the fixed-installation environment typical of building electrical distribution. Ambient temperature range is -40 to +75 °C for storage and operation, though the surrounding temperature influence note specifies periodic exposure to +55 °C at max 95% humidity — typical for an unventilated enclosure in a warm climate. Halogen-free and silicon-free construction means the materials do not release corrosive halogen gases under fire, which is a requirement for equipment installed in ventilated or occupied spaces where off-gassing could damage adjacent electronics or harm personnel.
