General Purpose Relays, CR420, Plug-In Relays

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.

- 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 customers.
- 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 termination.

Industrial/Machine Tool Relays, CR120B, 600 V, 10 Amperes Continuous, 60 Hz

The CR120B and CR120BL Series A, multi-circuit industrial relays are designed to meet most panel application requirements. They are available as standard or latched relays.

Industrial relays may be ordered as complete devices from the pricing tables with the NO and NC pole combination desired. The relay components may also be purchased separately and assembled in standard or latched forms (see Standard Components, page 10-18).

All forms of the relay mount on the same base, and in the same small panel-mounting area. Relays may be arranged in any configuration, or modified on a panel without altering the mounting area.

- Bifurcated contacts assure positive make: unique bifurcated contacts assure positive make at all voltages and give excellent fidelity even in harsh environments.
- Transparent Lexan®: contact cartridges allows inspection of contacts.
- Convertible contacts: allows conversion from normally open to normally closed, or vice versa. Just change the terminal screws and invert the contact module.
- Quick-change coil: can be changed without removing any screws.
