Yes, thanks to its compact dimensions of just 163 (H) x 55 (W) x 85.5mm (D), you'll find this adaptable gadget can make itself at home in tight spots.

The ’W’ series screw clamp terminals are suitable for ’Top Hat’ DIN Rail and manufactured from nylon 6.6 which has a continuous temperature rating of 120°C (180°C short term). They are self-extinguishing to UL94V-0 and free from cadmium and halogen. Current bars are constructed from 10 mm electrolytic copper to ensure a current loading more than nominal rating. Terminals are suitable for mounting on symmetric ’Top Hat’ rail only (BS5584:1978, EN 50022) and are touch proof in accordance with BS 3042.
