Product Information
Full details
This Weidmuller ZSI fuse row clamp (model 1616400000) is designed for electricians and control panel builders needing a reliable and easy-to-install component for protecting circuits. Its key benefit is the easily accessible, swiveling fuse holder for quick fuse replacement. A minor consideration is that it's designed for specific pipe fuse sizes (5 x 20 mm). This single-level terminal features a maintenance-free spring clamp connection, a 2.5mm² cross-section, and is rated for 500V and 6.3A.

FAQs
What type of fuse does this terminal accept?
This terminal accepts standard 5 x 20 mm pipe fuses.
What is the maximum wire size this terminal can accommodate?
The terminal can accommodate wire gauges from 26 AWG up to 12 AWG, with a maximum cross-section of 2.5 mm².
Is this fuse clamp suitable for outdoor use?
While the terminal has a wide operating temperature range, its suitability for outdoor use depends on environmental factors like moisture and dust. Ensure it is installed in an appropriate enclosure if exposed to the elements.
How do I install the wire into the clamp?
Strip the end of the wire to the appropriate length and insert it into the spring clamp opening. The spring mechanism will automatically secure the wire.
What voltage and current can this terminal handle?
This fuse row clamp is rated for a maximum of 500V and 6.3A.
Does this terminal require any special tools for installation?
Basic electrical tools for wire stripping and installation are required. The terminal itself mounts to a standard DIN rail.
What does 'maintenance-free' mean for the spring clamp connection?
'Maintenance-free' means the spring clamp connection is designed to maintain its grip over time without the need for periodic re-tightening, even under vibration.
Troubleshooting
Fuse repeatedly blows
Ensure the fuse rating is appropriate for the circuit load. Check for short circuits or excessive current draw in the protected device.
Wire connection is loose
Verify the correct wire gauge is used and that it is fully inserted into the spring clamp. Ensure the clamp is properly actuated to grip the wire. If using the maximum 2.5mm² section, ensure the wire is stripped to the correct length.
Terminal does not fit DIN rail
Confirm that a standard 35mm DIN rail is being used. Ensure the terminal's mounting clip is properly aligned with the rail.
Fuse holder is stiff to swivel
Ensure no debris is obstructing the hinge. Gentle cleaning may be required, but avoid lubricants unless specified by the manufacturer.
