Other improvements include:
- DIN Rail-Mounted Tail Clamp – Securely attached to the rail for faster, safer cable fitting
- Reinforced Grommet Strip – Provides strong, lasting cable protection at all entry points
🪛 Torque Accuracy = Safer Install
For compliance with BS7671, always use a torque screwdriver and follow the values listed in the included user manual. This ensures secure, long-lasting terminal connections.
