The 0090070291 contactor is a specialty product designed for a very specific application. It is intended for use in on-off switching circuits only. This article aims to explain the 0090070291 contactor\'s application field and working principle.The 0090070291 contactor is used for two main tasks: on-off switching and latching. It is designed to switch both AC and DC electric circuits, as long as their voltage and current ratings are within what the contactor can handle. It is commonly found in motor, heater and lighting control systems, for example.The 0090070291 contactor is a latching contactor, meaning that it remains in the state it is set in until it is reset manually. This is achieved through the use of two coils - a main coil and a latch coil. When the contactor is to be switched on, an AC or DC voltage is applied to the main coil. This creates an electromagnetic field that attracts the mechanical contacts inside the contactor, closing the circuit. This allows power to flow through the contactor. The latch coil works in tandem with the main coil by keeping the contacts closed, meaning the circuit remains on even when power is removed from the main coil.When it is time to switch the contactor off, power is removed from the main coil, and the latch coil releases the contacts, opening the circuit. This ensures that the circuit remains off until the contactor is reset.In addition to its practical applications, the 0090070291 contactor also has a convenient safety feature. It is designed with a built-in thermal overload protection mechanism. This ensures that the contactor will automatically cut the power supply if the current load on the contactor exceeds its rated capacity.Overall, the 0090070291 contactor is a versatile device that is both reliable and dependable. It is a particularly attractive choice for high-demand applications because of its latching feature, which keeps the circuit on even after power is removed from the main coil. Additionally, the thermal overload protection ensures that the contactor will fail safely even in emergency situations.
