Plug-In Relays
Application
The CR420 general purpose plug-in relays are commonly used
for low cost switching in many industrial control circuits. Typical
applications include industrial equipment , machine tool, HVAC,
lighting, vending, commercial appliances, elevators, and spa
controls.
These relays and sockets are powerful and highly cost effective.
Versions are available with AC and DC coils, plug-in or direct
flange mounting, and multiple contact configurations.
Features
—Cost Effective: Competitive every day prices make these relays
an excellent solution for low voltage industrial switching.
—Powerful: From 5 Amp (4 pole) to 30 Amp (1 pole), these relays
handle large loads in a compact package.
—Reliable Operation: 100% tested, ensuring performance the first
time. The long electrical life will give confidence and satisfied
customer
—Mechanical Indicator/Manual Operator: Helps field service
personnel test control circuits.
—LED Indicating Lamp: Easily show coil status under low light
conditions.
—IP20 Finger-Safe Sockets: Protects users from screws during
ter mination.
