Weidmuller Series W DIN Rail Terminal Block, Quadruple, 31A Current Rating - 7917030000

This DIN rail terminal block is designed for efficient wiring in industrial applications. It features a quadruple level configuration, perfect for connecting multiple conductors in a compact design. The terminal block operates effectively within a temperature range of -50°C to +120°C and is suitable for a variety of wiring types, accommodating American Wire Gauge sizes from 26 to 12 AWG.

Features & Benefits

• Supports screw termination for secure connections
• Rated for high current up to 31 A for robust performance
• Accommodates up to four levels for efficient space usage
• 500 V voltage rating ensures it meets high electrical demands
• CE and RoHS compliant, promoting safe environmental practices
• Constructed from durable Wemid for long-lasting reliability

Applications

• Used for motor connection in electrical installations
• Ideal for wiring distribution in control panels
• Suitable for phase wiring and protective conductor
• Designed for direct mounting on TS 35 rails in enclosures

What wiring specifications should be followed for optimal performance?

The optimal conductor connection range is between 0.5 mm² and 4 mm² for both solid and stranded wires. Ensure a stripping length of 8 mm for reliable connections and apply a tightening torque of 0.4 Nm to 0.6 Nm for secure capabilities.

How does this terminal block enhance installation efficiency?

Its quadruple level configuration allows for the convenient wiring of all three phases plus a protective conductor in a single block, simplifying installation and reducing the need for multiple connectors.

Are there specific temperature limits for this terminal block?

Yes, it operates effectively in environments ranging from -50 °C to +120 °C, making it suitable for various industrial settings where temperature fluctuations may occur.

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.
