Locate rail and align with non moveable 
end of CTR DIN clip.

Using reasonable force, push the CTR 
SSR in the direction of the arrow shown.

For removal pull release tag in direction 
of arrow using blade of screwdriver and 
pull it away from DIN rail.

Locate the panel section on which the 
CTR SSR will be monted on.

DIN clip includes tabs for this type of 
mounting. Tab holes have a diameter of 
4.5 mm. You will need two screws (not 
included) no larger than that to mount the 
SSR onto panel.

Align SSR tabs with panel surface and 
screw both top and bottom sides. 
Recommended torque is 12 in lb (1.36 Nm)

Maximum wire size of AWG#16 (1.29mm) on input and AWG#8 (3.26mm) on output terminals.

A solid state relay should be protected by a semiconductor fuse. This type of fuse 
provides extremely fast opening of the circuit. A fuse should be selected that has an I² t 
let-through rating that is less than the I² t capability of the SSR, for the same duration.

To achieve maximum ratings if multiple units are installed there must be a minimum air gap 
of 0.78 in (20 mm) between the devices (horizontally) and of 3.15 in (80 mm) measured 
between DIN clip tabs (vertically).

The CTR heatsink is equiped with an earth bonding screw as is required for Class 1 
Protection, in accordance with EN 60950 (VDE 0804). 

Recommended torque is 12 in lb 

(1.36 Nm).

Ensure that wire ends for termination conections are stripped to a minimum lenght of 0.4 in (10 mm).

5 in lb (0.6 Nm) on input and 15 in lb (1.7 Nm) on output.

The air gap is the clearance distance adjacent to either side of the relay or assembly 
measured to the next closer relay or assembly.

Crydoms CTR Series Solid State Relays were developed to offer the advantages of semiconductor 
switching technology in a compact, self contained package. Quick and easy installation is 
coupled with low drive power requirements and efficient, reliable power SCR output.
