Protect your electrical systems against short circuits and overcurrent with this fused DIN rail terminal from Weidmuller. When faults occur, the fuse blows to prevent damage and lengthy downtimes. The robust Wemid housing insulates live components for improved safety in your enclosures. This material is also self-extinguishing to limit the spread of fires. Thanks to its voltage rating of 500V, it's suitable for use in low-voltage applications. For ease of installation, simply snap it onto your DIN rail.

• Wide operating temperature range between -50°C and +120°C for use in harsh conditions
• Compact dimensions of 50.7 (H) x 8 (W) x 42.5mm (D) for ease of installation in tight spaces

• Energy systems
• Power supplies
• Lighting controllers
• Telecommunications
• Automated factory operations

Start by turning off all relevant equipment and stripping the wire. Then loosen the screw in the entry slot, insert the exposed conductors and tighten. It's important to make sure this connection is secure for proper signal transmission.

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.
