The 1-pole + N design switches the neutral, so it suits single-phase final subcircuits where isolating both conductors is required.
Occupies one modular width (18 mm) on standard DIN rail — snap-on mounting in any position. Rated 25 A at 30 °C; derates to 24 A at 40 °C and 23.5 A at 45 °C.
Rated 4.5 kA per EN 60898 at 230 V AC. That is the maximum fault current it can safely interrupt under standard test conditions.
Sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — no stock count or price is published here.
Yes. It is a 1-pole + N design with neutral conductor switching, so both line and neutral are disconnected when the breaker trips or is manually opened.
The breaker is designed per EN 60898 and IEC 60947-2 standards. It carries IP20 protection (with conductors connected), pollution degree 2, and overvoltage category III. Specific RoHS/REACH/UL declarations should be requested at quote time from the supplier.
