STRAZH 3-30 is designed for automatic control and subsequent disconnection of the load (consumer) from the mains in case of emergencies in a single-phase mains in three parameters: voltage, current, leakage current (RCD). The machine reduces the risk of damage to household electrical appliances as a result of emergencies in the power grid. The machine is recommended for use in household and industrial electrical installations. The total load power should not exceed 6.5 kW, taking into account the starting currents.
Technical capabilities
Voltage control:
1. The upper threshold (with an adjustable parameter response time) allows you to protect the consumer from overvoltage and voltage surges.
2. The lower threshold (with an adjustable parameter response time) allows you to protect the consumer from undervoltage and voltage dips.
3. The zero break threshold (with a fixed response time of 0.04 sec.) Protects the consumer from zero break.
Current control (parameter with adjustable response time) - allows you to protect the electrical installation from increased, emergency current consumption by the load.
RCD leakage current control (with an adjustable response time parameter) - allows you to protect people from electric shock in the event of a phase breakdown on the electrical appliance case.
