SELECT THE RIGHT VERSION
Standard 20–40A 2–4-pole versions use a compact 100 × 160 × 90mm enclosure, with blank faces for cable-entry preparation.
The 20–40A .W versions use a wider 150 × 160 × 90mm enclosure for additional wiring space. Choose .WSN to combine that extra room with an unswitched solid neutral.

Match dimensions to the exact part number before mounting or drilling. Cable glands and the completed installation must suit the required enclosure protection.
Up to two auxiliary contacts can be fitted per switch. Select by switch size and the required operating sequence.
| Switch size | Accessory code | Contact / operation | Rating at 250V |
|---|---|---|---|
| Y1 | 590.PL004001 / 590.PL004002 | NC / NO options · simultaneous with main contacts | 16A |

| Y3 · Y4 · Y5 | 590.PL005 | NO/NC · breaks before main contacts | 15A |
Codes listed in the supplied catalogue. Confirm compatibility for the exact switch, including any Y2 configuration. Auxiliary contacts are accessories and are not implied to be included.
Choose the neutral configuration required for the installation.
| Configuration | Neutral operation | Identification |
|---|---|---|
| 4P (3P+N) | Neutral is switched, with early-make / late-break operation. | 05 pole code without a solid-neutral suffix |
| 3P+SN | Three switched phases plus an unswitched neutral terminal block. | .SN suffix |
| 3P+SN · high wiring | Unswitched neutral with extra enclosure space. | .WSN suffix |
The neutral in a 3P+SN model is a through terminal block, not a switched pole.
