CKR Series
Crydoms CKR Series Solid State Relays were developed to offer the advantages of semiconductor switching technology in a
standard 22.5mm industrial package. Quick and easy installation is coupled with low drive power requirements and efficient,
reliable power SCR output. Box Clamp terminals and LED status indication complete the package. This compact new design
offers up to 30Arms in ambient temperatures of 25C.
Manufactured in Crydom’s ISO 9001 Certified facility for optimum product performance and reliability.
APPROVALS: UL, CSA, VDE, CE Mark.
MOUNTING OF CKR SERIES OF SOLID STATE RELAYS
CKR Series SSRs are designed to fit to an industry standard TS35 DIN Rail. Mounting clip incorporates tabs for screw mounting to panel.
MOUNTING TO THE DIN RAIL
Locate rail and align with non moveable
end of CKR DIN clip. Using reasonable
force, push CKR in the direction of the
arrow shown.
REMOVAL FROM DIN RAIL
Pull release tag in direction of arrow using
blade of screwdriver.
MOUNTING CONSIDERATIONS
To achieve maximum ratings, there must be
minimum spacing of 0.8 inch (20mm)
between the devices in free air.

THERMAL CONSIDERATIONS
The CKR power switching range is based on semiconductor
technology and therefore generates heat during operation.
The following derating curves must be observed before installation.
Crydom products are rated for 100% Duty Cycle.

GENERAL NOTES
All parameters at 25°C unless otherwise specified.
Off-State dv/dt test method per EIA/NARM standard RS-443, paragraph 13.11.1
Turn-on time for DC control random turn-on versions is 0.02msec.
Input circuitry for DC control version incorporates active current limiter.
PROTECTION
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 I 2t let-through rating that
is less than the I 2t capability of the SSR, for the same duration.
Transient Over Voltage (P OPTION)
Select "P" option for internal overvoltage protection. At the
presence of high voltage transient the output of the SSR will be
triggered on, and the transient will be passed on to the load circuit
This is a non-degrading method of protection that ensures that
other SSR benefits are maintained.
Earth Bonding (Grounding)
The CKR heatsink is equiped with an earth bonding screw as is
required for Class 1 Protection, in accordance with EN 60950
(VDE 0804).
Terminations
Wire Size
• Maximum wire size of AWG#10 (3mm) on
both input and output terminals.
Connections • Ensure that wires ends are stripped to a
minimum length of 0.4 inch (10mm).
Recommended Screw Torque Range
• 5.0-6.0 in lb (0.6-0.7 Nm) on input and output termination.
