Using reasonable force, push CKR in the direction of the arrow
shown in fig.1.
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.

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

High Power Ready-to-Use DIN Rail Mounted SSRs
Please read all installation instructions before using CKR Series SSRs.
Align SSR tabs with panel surface and screw both top and bottom
sides. Recommended torque is 12 in-lbs (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 equiped with an earth bonding screw as is required for Class 1
Protection, in accordance with EN 60950 (VDE 0804). Recommended torque is 20 in-lbs
(2.2 Nm).
