FAQs
What type of DIN rail is required for the KH23C?
The Hager KH23C is designed for mounting on a standard 35mm symmetrical DIN rail.
What is the maximum current rating for this terminal block?
The terminal block is rated for a maximum of 80 A.
Can I use stranded wires without end sleeves?
The terminal is specified for solid/multi-core cables from 1.5 to 25mm² and flexible cores *with wire end sleeves* from 1.5 to 16mm². It is recommended to use wire end sleeves for flexible conductors for optimal performance and safety.
How many connections are available per pole?
Each pole has 4 connection points.
What are the dimensions of the KH23C?
The dimensions are 69.2 mm (Width) x 45.5 mm (Depth) x 65.9 mm (Height).
Is this terminal block suitable for outdoor use?
The product description does not specify outdoor use. It is designed for industrial and commercial settings, typically within enclosures or control panels.
What is the difference between solid/multi-core and flexible core cable ratings?
Solid/multi-core cables can be used from 1.5 to 25mm², while flexible cores require wire end sleeves and are supported from 1.5 to 16mm².
Troubleshooting
Terminal block not securing to DIN rail
Ensure the DIN rail is the correct 35mm symmetrical type and is properly mounted. Check for any obstructions on the rail or the terminal block's mounting clip.
Loose cable connection
Re-insert the cable and ensure it is stripped to the correct length. Tighten the terminal screw firmly. For flexible cables, ensure a proper wire end sleeve is used and crimped correctly.
Overheating at a terminal point
Immediately disconnect power and inspect the connection. Ensure the cable size is within the specified range (1.5-25mm² for solid/multi-core, 1.5-16mm² for flexible with sleeves) and the screw is adequately tightened. Check for corrosion or damage to the cable conductor.
