RGC3A60A25KKE

Contactors (Solid State) describe components used to control electrical circuits. The RGC3A60A25KKE is a series of contactors that utilizes a sealed, electrically isolated, dust and moisture proof structure to control electrical circuits. It is a combination of mechanical contact, electronic hysteresis, and thermal regulation controlled by an internal microprocessor embedded in a central carrier module. The device has a high combustion intensity with a low spark energy and is resistant to wear. The contactor is best suited for applications in air conditioning, refrigeration, solenoid valves, and pneumatic valves.

The unique operation of the RGC3A60A25KKE, the combination of mechanical contact and thermal regulation, allows it to control the current in a circuit with the utmost accuracy and precision. In any given application, the mechanical contact allows safe separation of the primary and secondary circuits, while the electrical hysteresis regulation allows the controller to maintain a constant and defined breaking current. Additionally, the thermal regulation feature ensures the switching element does not overheat and maintains safe operation.

Using Dry Reed Contactors, the RGC3A60A25KKE can provide up to 20 kW for a single contact. When used to control large currents, the contactor will be equipped with a Forced Air Cooling system and an auxiliary contactor to ensure over-current protection. Additionally, the Forced Air Cooling system will use thermal sensors to monitor the contactor state. The contactor has a wide frequency response from 50 Hz to 400 Hz.

The contactor is resistant to power surge and over-voltages and extreme temperatures. Additionally, its electrical insulation is equivalent to 6 kV/mm and the power resistor can reach as high as 100 kW. This contactor is significant for its environmental adaptability, and is rated for a wide range of temperatures including -46 degree Celsius through 105 degree Celsius.

The RGC3A60A25KKE is a contactor-driven motor protection, specifically designed for emergency and security switchgear applications. It has a high contact voltage rating and a sound detection operation that monitors the current in the circuit and uses the internal heater to activate the contact closing. Its integrated timer runs for up to 30 minutes and can be triggered by an external signal or an internal signal.

The contactor\'s operation is based on the general principles of a contactor system. This system is made up of a set of switching contacts, that interconnect and open and close the electrical circuit as required. Therefore, when positive voltage is applied to the contactor circuit, it has to be greater than the holding voltage to close the circuit. The process is reversed when negative voltage is applied to the contactor. In addition, the contactor provides reliable and superior current control as the circuit alternates between the open and closed states.

The contactors are also designed with an auto reset function that allows the contactor to re-open and re-close the circuit once the current drops below the holding current. Furthermore, the contactor\'s also maintain high performance and efficiency even when subjected to varying power flows and frequent switching. The contactors are well suited optimal performance even when required to switch off hundreds of times in a single day.

In conclusion, the RGC3A60A25KKE series of contactors is a reliable and efficient contactor system. With its dust and moisture proof sealed construction and its high switching performance, it is suitable for a range of applications that require reliable and precise current control. Its wide temperature range and power resistor support ensure that it can be utilized in conditions challenging to other contactor systems.
