The TOWJR-2-63 Voltage and Current Protection Relay is designed to protect 230V AC electrical circuits and connected equipment against overvoltage, undervoltage, and overcurrent conditions.

It automatically disconnects the load when the monitored voltage or current exceeds the configured protection limits. Once normal operating conditions are restored, the device can automatically reconnect the load after the selected recovery delay.

Designed for standard 35mm DIN rail installation, it is suitable for distribution panels, residential electrical systems, workshops, equipment protection, and other single-phase AC applications.

Protection Functions

The TOWJR-2-63 provides three primary protection functions: overvoltage protection, undervoltage protection, and overcurrent protection.

Protection thresholds, action times, and recovery delays can be configured according to the requirements of the connected electrical system. Automatic recovery allows the load to be reconnected after voltage or current conditions return to the configured acceptable range.

The adjustable power-on delay can also help prevent immediate reconnection of equipment when power is restored.

Applications

Suitable for residential distribution boards, electrical panels, workshops, small commercial installations, appliances, pumps, motors, refrigeration equipment, and other compatible 230V single-phase electrical loads requiring voltage and current monitoring.

Important Safety Note

This device operates directly from 230V AC mains voltage. Installation, configuration, and wiring should be performed by a qualified electrician.

Select the correct 40A or 60A version according to the electrical installation and load requirements. Appropriate upstream circuit protection must still be used; this protection relay should not be treated as a replacement for all required circuit breakers, fuses, or other electrical safety devices.
