Modular | Digital Voltage Monitoring Relay | 1F | 63A | 230V | DIN | ETVPS1-63C

Modular digital voltage control relay – 1P 63A 230V DIN

Modular digital voltage control relay, designed to protect a single-phase 230 V electrical system against dangerous voltage fluctuations, undervoltage, overvoltage and overcurrent. The relay continuously monitors network parameters and, when the set limits exceed permissible values, automatically disconnects the load. When the voltage or current returns to the set limits, the device can automatically restore the power supply after the set delay time.

• Residential houses – for protecting household appliances, heating controllers, pumps and electronics.
• Apartments and cottages – for voltage control of single-phase electrical installations.
• Workshops and garages – for protecting tools, compressors, automation and technical equipment against voltage fluctuations.
• Agricultural facilities – for protecting pumps, fans, refrigeration, heating and other 230 V devices.
• Electrical panels – as a modular DIN rail device for monitoring a single-phase line.

For example, the relay is installed in an electrical panel on a DIN rail before the protected single-phase load or load group. The device monitors the network voltage and current, and when the set limits are exceeded, it disconnects the power supply. When the voltage and current return to a safe range, the relay can automatically switch the power supply back on after the set delay time.

This solution is useful where the electrical network is unstable, voltage drops or surges occur frequently, or when additional protection for more expensive electrical devices is desired.

The voltage control relay is a protection and control component for an electrical panel, therefore before installation it is necessary to evaluate the load, cable cross-sections, circuit breaker rating, earthing, protection devices and the specific electrical diagram.

• Installation must be carried out by a qualified electrician, in accordance with applicable electrical safety requirements.
• The rated current of 63 A must not be exceeded – higher loads require an additional solution.
• The relay does not replace a circuit breaker – the circuit still requires short-circuit and overload protection according to the diagram.
• The relay does not replace RCD / RCBO – separate protection devices are required for personal protection against leakage current.
• The relay does not replace a surge protection device – SPD is required for protection against lightning and impulse overvoltages.
• Before use it is necessary to set suitable voltage, current and delay limits according to the specific equipment.

Quick selection guide

This is a suitable choice when protection of a single-phase 230 V electrical system against overvoltage, undervoltage and overcurrent is required. The relay is mounted on a DIN rail and allows the main operating parameters to be adjusted according to the specific load.

Smart protection of a single-phase electrical line against voltage fluctuations

The digital voltage control relay helps protect 230 V electrical equipment against overvoltage, undervoltage and overcurrent by automatically disconnecting the load during dangerous network parameter conditions.

Thanks to adjustable limits, automatic recovery, DIN rail mounting and 63 A rated current, this relay is a practical solution for electrical panels in homes, workshops, agricultural facilities and technical sites.
