Product Description

The CRYDOM CMRA4845 is a DIN-Rail Mounted Solid State Relay with an AC output, featuring a Form A (SCR) switch configuration. It supports an output voltage range of 48 to 530V AC and a maximum output current of 45 A without a heat sink, with an input current of 15 mA. The relay offers a cage-type electrical connection and is finger safe for enhanced safety during installation.

Frequently Asked Questions

What is the CRYDOM CMRA4845 solid state relay used for?

The CRYDOM CMRA4845 is used for switching AC loads in industrial automation, HVAC, and process control systems. Its DIN-rail mounting and finger-safe cage connections simplify panel installation. The SCR output handles 48 to 530V AC at up to 45 A without a heat sink, making it suitable for resistive and inductive loads.

What are the specifications of the CRYDOM CMRA4845?

The CRYDOM CMRA4845 is a DIN-rail mounted solid state relay with AC output, 48 to 530V AC output voltage, 45 A maximum output current without heat sink, 15 mA input current, Form A (SCR) switch configuration, and cage-type electrical connection. It is finger safe for operator protection.

Where to buy the CRYDOM CMRA4845 worldwide?

You can source the CRYDOM CMRA4845 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; we provide competitive pricing and reliable sourcing for this CRYDOM relay.

How to install the CRYDOM CMRA4845 solid state relay?

Mount the CRYDOM CMRA4845 on a DIN rail in a clean, dry enclosure. Use cage-type terminals for secure wiring of AC output (48 to 530V AC) and DC input (15 mA). Ensure adequate airflow for heat dissipation at 45 A. Follow standard electrical safety practices and verify polarity-free connections.

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.
