- The recommended torque for tightening the earth bonding screw is 20 lb-in (2.2 Nm) as per Class 1 Protection requirements.

Crydom CKR Series Solid State Relays were developed to offer the advantages of semiconductor switching technology in a standard 22.5 mm industrial package. Quick and easy installation is coupled with low drive power requirements and efficient, reliable power SCR output. This compact new design offers up to 30 Arms in ambient temperatures of 25ºC.

FEATURES

The mounting clip incorporates tabs for screw mounting to the panel
Box Clamp terminals
The bracket fits all standard 35 mm DIN rail profiles
LED input status indicator

INSTALLATION INSTRUCTIONS

Please read all installation instructions before using CKR Series SSRs. Choose one of the two mounting options and follow the instructions below.

Mounting on DIN Rail

Locate the rail and align it with the nonmoveable end of the CKR DIN clip.
Using reasonable force, push CKR in the direction of the arrow shown in fig.1.
For removal pull the release tag in the direction of the arrow using the blade of screwdriver and pull it away from the DIN rail.

Mounting on Panel

Locate the panel section on which the CKR SSR will be mounted.
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 the panel.
Align SSR tabs with the panel surface and screw both top and bottom sides. Recommended torque is 12 lb-in (1.36 Nm).

IMPORTANT CONSIDERATIONS

Mounting Air Gap (A)
- To achieve maximum ratings, there must be a minimum spacing of 0.8 in (20 mm) between the devices (horizontally) and of 3.15 in (80 mm) measured between DIN clip tabs (vertically).
Earth Bonding (Grounding)
- The CKR heat sink is equipped with an earth bonding screw as is required for Class 1 Protection, following EN 60950. Recommended torque is 20 lb-in (2.2 Nm).

ORDERING OPTIONS

NOTE: Not all combinations are available. Consult the factory for information on the availability of a specific part number.

WIRING DIAGRAM

Wire Size
- Maximum wire size of AWG #10 (5.3 mm2 ) for input and output terminals.
Connections
- Ensure that wire ends are stripped to a minimum length of 0.4 in (10 mm).
Recommended Screw Torque Range
- 5-6 lb-in (0.6-0.7 Nm) on input and output terminations.

GENERAL NOTES

(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.
(B) 100% Duty Cycle.

DERATING CURVES (B)

The following dating curves must be observed before installation.
