Frequently Asked Questions

What is the CRYDOM CMRA4865 solid state relay used for?

The CRYDOM CMRA4865 is used for switching AC loads in industrial automation, HVAC, and process control systems. Its DIN-rail mounting and SCR output make it suitable for high-cycle applications requiring reliable, silent switching without mechanical wear.

What are the specifications of the CRYDOM CMRA4865?

The CRYDOM CMRA4865 is a DIN-rail mounted solid state relay with AC output from 48 to 530V AC, maximum output current of 65 A without heat sink, input current of 15 mA, cage-type electrical connection, and finger-safe design. It uses a Form A switch configuration with SCR output.

Where to buy the CRYDOM CMRA4865 worldwide?

You can source the CRYDOM CMRA4865 through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to worldwide destinations. Contact us for availability and lead time.

How to install a CRYDOM DIN-rail solid state relay?

Snap the CRYDOM CMRA4865 onto a standard DIN rail. Ensure the relay is oriented correctly and the cage-type terminals are tightened to the recommended torque. Use a heat sink if the load current exceeds 65 A. Follow CRYDOM's installation manual for wiring and safety.

Used in

Common applications for CRYDOM
Industrial heating — Crydom 53TP series SSRs control resistive heating elements in furnaces and ovens, with zero-voltage switching to reduce electrical noise.
Plastics machinery — Dual Crydom SSRs (e.g., CC4850W2V) manage barrel heater bands and mold temperature controllers, providing independent control of multiple zones.
Packaging equipment — Panel-mounted Crydom SSRs switch motors and solenoids in high-speed packaging lines, offering long life and resistance to vibration.
Lighting control — Crydom triac-output SSRs (e.g., 21R940) dim or switch industrial lighting circuits, with finger-safe terminals for operator safety.
HVAC systems — Crydom SSRs regulate compressors and electric heaters in commercial HVAC units, with AC input compatibility for direct control from thermostats.
Water treatment — Crydom SSRs switch pumps and valves in water treatment plants, with SCR output for inductive load control and heat sink options for high ambient temperatures.
