**Voltage and current relay** for continuous monitoring of electrical network parameters and protection of equipment from voltage fluctuations, overloads and current surges. The devices are used in single-phase and three-phase networks to prevent failure of household and industrial appliances, ensuring timely disconnection of the load when parameters deviate from the specified limits.
* Network type: single-phase, three-phase
* Switched current: up to 63 A
* Voltage adjustment range: 180–270 V
* Response time: from 0.1 to 10 seconds
* Protection degree: IP20
* Indication: LED or LCD display (depending on the model)
**Advantages:**
* Automatic protection prevents equipment damage during voltage and current surges
* Ability to adjust trip thresholds for specific conditions
* Status indication allows visual monitoring of network parameters
* Modular housing and convenient connection
