This finger-safe relay features a box-clamp electrical connection and delivers a maximum output current of 20 A without a heat sink.

Supplied to the Philippines — compatible with 60 Hz installations. DHL Express delivery to Manila, Quezon City, Cebu, customs and duties handled door-to-door.

Frequently Asked Questions

What is the CRYDOM CKRD2420 solid state relay used for?

The CRYDOM CKRD2420 is a DIN-rail mounted solid state relay used for switching AC loads in industrial control panels, HVAC systems, and process automation. Its SCR output and 20 A rating suit motor starters, heaters, and lighting controls where silent, vibration-free operation is needed.

What are the specifications of the CRYDOM CKRD2420?

The CRYDOM CKRD2420 is a DIN-rail mounted solid state relay with SCR, AC output. It accepts 8 to 12 mA DC input, switches 24 to 280V AC output, and delivers up to 20 A without a heat sink. It features a Form A (SPST-NO) switch, box-clamp connection, and finger-safe design.

Where to buy the CRYDOM CKRD2420 worldwide?

3G Electric supplies the CRYDOM CKRD2420 solid state relay to customers worldwide. As a global industrial sourcing partner, we handle logistics, customs clearance, and delivery to your facility. Contact us for pricing and lead time on this DIN-rail mounted relay.

How to install a CRYDOM CKRD2420 solid state relay?

Mount the CRYDOM CKRD2420 on a standard DIN rail. Use box-clamp terminals for secure wiring: connect DC input (8–12 mA) to the control side and AC load (24–280V AC) to the output. Ensure adequate airflow for heat dissipation; a heat sink is not required at 20 A. Follow local electrical codes.
