CTR Series

DIN rail mountable SSRs

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.

MOUNTING INSTRUCTIONS

Please read all installation instructions before using CTR series SSRs.

Choose one of the two mounting options and follow the instructions below.

MOUNTING ON DIN RAIL

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.

MOUNTING ON PANEL

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)

IMPORTANT CONSIDERATIONS

Mounting air gap

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).

Over Current and Short Circuit

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.

Earth Bonding (Grounding)

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).

A

Wire Size

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

Conections

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

Recommended Screw Torque Range

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

A

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