Installation Guidelines

• Mounting: The device is designed for easy snap-on mounting onto standard DIN rails within electrical distribution boards.
• Wiring: Ensure all power is disconnected before installing or replacing fuses. Use appropriate terminal torque to ensure secure connections and prevent overheating.
• Fuse Selection: Always use a fuse with the correct current rating and characteristics (8.5 x 31.5 mm) as specified for the application to ensure effective protection.
• Maintenance: Since this is a Phase-Out product, ensure that your inventory of compatible fuses is maintained to avoid downtime during future maintenance cycles.
