C301NU50

Power Relays, Over 2 Amps

The C301NU50 is a general purpose high-current relay, designed for applications requiring high-reliability and electrical isolation. It is a three-pole double-throw (3PDT) device with a maximum current rating of 2 A and a maximum voltage rating of 250 VAC.

Application Field

The C301NU50 is designed for use in a variety of applications in industrial, commercial, and residential settings. It is suitable for controlling DC motors, pumps, solenoids, xenon strobes, LED indicators, and other similar devices. The C301NU50 has a wide range of applications, including:

• Automotive: Horns, wipers, window washers, fans, lighting, power locks, and door-open indicators.
• HVAC control: motorized dampers, gas safety shutoff valves, zone valves, fan speed control, and compressor/condenser motors.
• Home Automation: Security systems, pumps, garage door openers, lighting, and thermostats.
• Industrial: Process control, solenoids, security applications, robotics, conveyors, pumps, vending machines, and packaging.

Working Principle

The C301NU50 works by using an electromagnetic coil to activate the internal contacts. When the coil is energized, it creates a magnetic field which pulls the internal contactor into position. The C301NU50 has a latching type mechanism, meaning that once the contactor is in place, it remains there until the coil is de-energized.

The contacts of the C301NU50 are designed to handle the load current when in use. The contacts are made from silver alloys and corrosion resistant low temperature material, which helps ensure long life. The contacts can also handle transient current surges due to the high-grade copper alloy they are made from.

The contact rating of the C301NU50 is 2 A with a maximum voltage of 250 VAC. The device is UL and CSA approved and has a UL 94 V-0 flammability rating, which ensures it is safe to use in most indoor locations.

Conclusion

The C301NU50 is a general purpose high-current relay, suitable for a wide range of applications that require reliability and electrical isolation. It is a 3PDT device, with contacts rated for 2 A, 250 VAC. The device is UL and CSA approved, and has a UL 94 V-0 flammability rating. Its latching type mechanism ensures that the contactor remains in position once it is activated.
