At 70 mm wide and 152 mm deep, it fits standard panel layouts with 10 mm clearance upwards, downwards, and at the side, plus 20 mm forward for arc chute clearance. Wiring accepts solid conductors from 0.5 to 1.5 mm² (2x) and stranded up to 70 mm², covering main power and auxiliary circuits through the same screw-clamp interface.
Side-by-side mounting is supported, and up to two auxiliary switch blocks can be attached directly to the contactor frame without extra hardware.
This part is sourced and quoted to order against an RFQ through independent distribution; availability and current pricing are confirmed at quote time.
Both share the S3 frame size and 70 mm width, so the physical footprint is identical; however, verify the coil voltage and auxiliary contact configuration — the 3RT2536 series may differ in coil type or terminal layout.
Depth is 152 mm; the main power terminals accept stranded conductors up to 70 mm², and auxiliary terminals accept solid 2x (0.5 to 1.5 mm²) or 2x (0.75 to 2.5 mm²).
