The ERZ-E10E681 is a type of transil device, which can be classified under TVS - Varistors, MOVs. This device is a combination of surge protective and filtering functions, used to protect vulnerable surges from external environments. Let’s explore further into application field and working principles of the ERZ-E10E681.

Application Field

When the ERZ-E10E681 is installed and used correctly, its primary purpose is to protect equipment, systems, and components from high levels of transient voltage. The device is compatible with many types of systems including air conditioning and refrigeration systems, telecommunications systems, elevator systems, and other industrial systems. Its high surge protection capability is able to withstand up to 8 kV and 50 A of surges. Additionally, the ERZ-E10E681 has high resistance to noise so that it can suppress electromagnetic interference (EMI) produced from external environments.

Working Principles

The ERZ-E10E681 possess two main components: a MOV and a varistor. MOV, or Metal Oxide Varistor, is a semiconductor component that can limit overvoltage with a very high discharge current. It works by conducting current away from delicate components exposed to externally generated spikes. A varistor, on the other hand, is a type of capacitor that is used to protect against electrical transients. It absorbs high currents caused by unexpected spikes, thus protecting vulnerable elements in a circuit.

These two components are linked together and functions in synergy when exposed to external transients. Both components depend on its surrounding temperature when responding to the transients. In normal operation, the MOV acts as a resistive element and the varistor as a capacitive element. When the alarm threshold is triggered, both components experience a conduction process. The varistor will be further charged and can now provide a short circuit path for the transients, while the MOV will dissipate the energy through the ground.

Conclusion

The ERZ-E10E681‘s combination of a MOV and varistor allows this device to provide both surge protection and noise suppression capabilities. It has many applications in air conditioning and refrigeration systems, telecommunications systems, elevator systems, and other industrial systems, making it the ideal component choice for such systems. It is worth noting that special consideration needs to be given to system design, particularly in terms of temperature conditions, to guarantee proper operation of the device.
