The General Electric (GE) CR120C04002AA relay is a versatile and reliable electrical switching component designed for use with 115 volts at 60 hertz. This particular model is part of GE's Contact Relay series, which is known for its durability and dependability.
The CR120C04002AA is a normally open, single-pole, double-throw (SPDT) relay, which means it can switch one circuit on or off based on an input signal. It features 12 contacts, with 6 form A contacts and 6 form B contacts, providing multiple options for wiring and application flexibility.
The relay's contacts are rated for a maximum contact capacity of 10 amps at 115 volts, ensuring they can handle a reasonable amount of current flow without degrading or failing prematurely. The contact material is silver alloy, which offers excellent conductivity and reduces the risk of contact welding and arcing.
The CR120C04002AA has a coil voltage rating of 120 volts AC and a coil resistance of 155 ohms, allowing it to be easily driven by a wide range of control circuits. It also has a maximum operating temperature of 70 degrees Celsius (158 degrees Fahrenheit) and a maximum ambient temperature of 40 degrees Celsius (104 degrees Fahrenheit), making it suitable for use in various environments.
One notable feature of this relay is its quiet operation, which is essential in applications where noise levels must be kept low. It also has a fast switching time, which reduces the risk of nuisance tripping and ensures smooth and efficient switching of loads.
The CR120C04002AA is designed with a robust construction, featuring a molded case made of thermoplastic material that offers excellent insulation and protects the internal components from moisture and other environmental hazards. It also has a built-in current limiting resistor that helps protect the coil from damage due to overcurrent conditions.
In summary, the General Electric CR120C04002AA relay is a high-quality, versatile, and reliable electrical switching component that can handle 115 volts at 60 hertz and is suitable for various applications where switching capacity is required. Its quiet operation, fast switching time, and robust construction make it an excellent choice for those seeking reliability and performance in their electrical systems.
