Test-disconnect terminal blocks feature both spring and screw connection technology that allow for creating the converter circuits needed for measuring current, voltage and power.

• Current and voltage transformer wiring
• Measures parameters safely and sophisticated
• Snap-on mounting

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.
