What it is and what it does
The 3RT1526-1AP00: Rated impulse withstand voltage is 6 kV for main and auxiliary circuits.
Mounting and wiring details
Fastens with screws or snaps onto a 35 mm DIN rail per EN 50022. Accepts solid or stranded wire: 2x 0.5…1.5 mm², 2x 0.75…2.5 mm², or up to 2x 4 mm² for the main circuit. The AWG equivalents are 2x 20…16, 2x 18…14, or 1x 12. Side-by-side mounting is allowed (zero gap), saving rail space. The contactor can be rotated 180° on a vertical surface or tilted ±30° front/back, which helps in tight enclosures. Clearance to adjacent parts: 6 mm at the side. Arcing time is 10…15 ms, and the contactor picks up in 13…25 ms at AC – both standard figures for this frame.
