The mirror contact design per IEC 60947-4-1 ensures the NC contact reflects the main contact state — critical for safety circuits where a welded main contact must not go undetected.
Width of 10 mm and depth of 66 mm keep the auxiliary block compact on the DIN rail. Snap-on fastening means no tools for initial mount — press onto the contactor side until the latch engages. The IP20 front protection is standard for enclosed panels; no washdown rating here, so keep it behind a gland plate or cabinet door.
Rated operational current varies by voltage: 6 A at 24 V and 230 V, 3 A at 400 V, 1 A at 690 V AC-15. For DC switching, the block handles 6 A at 24 V, 2 A at 48/60 V, 1 A at 110 V, 0.9 A at 125 V, and 0.3 A at 220/250 V.
