Vigirex RH is a type of residual current relay (RCCB) manufactured by Schneider Electric. Here's an overview of Vigirex RH:

Vigirex RH Residual Current Relay:

1. Residual Current Protection: The Vigirex RH is designed to provide protection against residual currents, also known as earth leakage currents or ground faults. These currents can occur when there is a fault in the electrical installation, such as insulation breakdown or contact with water.
2. Sensitivity and Thresholds: The Vigirex RH is available in various sensitivity ratings to suit different applications and requirements. It can detect small leakage currents as low as a few milliamperes, providing early warning of potential electrical faults.
3. Alarm and Trip Functions: In addition to detecting residual currents, the Vigirex RH can provide alarm and trip functions to initiate protective actions when a fault is detected. It can trip circuit breakers or disconnect power to prevent electric shocks, fires, or damage to equipment.
4. Monitoring and Diagnostics: The Vigirex RH may include monitoring and diagnostic features to continuously monitor the health and performance of the electrical installation. It can provide information on current levels, fault conditions, and system status to aid in troubleshooting and maintenance.
5. Communication and Integration: Some models of the Vigirex RH may include communication capabilities, allowing them to be integrated into larger control and monitoring systems. This enables remote monitoring, data logging, and coordination with other protective devices.
6. Compact Design: The Vigirex RH is designed to be compact and easy to install, making it suitable for a wide range of applications, including residential, commercial, and industrial settings.
7. Reliability and Compliance: Schneider Electric products are known for their reliability and compliance with international standards and regulations for electrical safety. The Vigirex RH is designed and manufactured to meet these requirements, ensuring safe and reliable operation.

Overall, the Vigirex RH residual current relay is a critical component of electrical safety systems, providing protection against earth leakage currents and helping to prevent electric shocks, fires, and damage to equipment.
