The IP20 finger-safe terminals are fine inside a panel — no washdown rating, no outdoor use without a secondary enclosure. That's a step up from the PD2 rating on the 5SL and some 5SY variants — relevant if the panel sits near a compressor or in a non-conditioned electrical room.
Panel fit and compatibility
Single-pole, no neutral switching — it breaks only the line conductor. That's standard for single-phase branch circuits where the neutral is bonded elsewhere. The AC/DC voltage type means it can also switch DC loads up to 240 V, though the breaking capacity on DC isn't separately listed here; treat the DC rating as lower than the 3 kA AC figure unless the datasheet confirms otherwise. Energy limiting class 3 restricts let-through energy. At 50 Hz only.
