ENGINEERING CASE STUDY

# Electrical Protection Devices

Voltage, current and earth leakage protection electronics.

Concept view of electrical protection switches, a relay and a current sensor.

## The project

Nexora developed electronics for a range of electrical protection devices. The work covers an earth leakage protection relay and a smart protection switch that combines under-voltage, over-voltage, over-current and earth leakage functions. The purpose is to recognise specified fault conditions and initiate the intended protective action.

## The engineering challenge

Protection products bring sensing, decision-making and switching interfaces together. The engineering challenge is to keep the monitored condition, configured limit and resulting action consistent across the circuit and assembled hardware. This project addresses that electronics layer; selection for a particular electrical installation still depends on its requirements.

## Engineering scope

- Earth leakage protection relay electronics
- Combined voltage, current and earth leakage monitoring
- Schematic design, PCB development and product testing

## From circuit design to product testing

Nexora’s work on this product covers three connected stages. Schematics define the circuit and its interfaces. PCB development turns that design into a physical board. Product testing evaluates the assembled electronics against the intended operating requirements.

## Where it can help

The work supports equipment makers developing electrical monitoring and protection products. Trip thresholds, response times, ratings and conformity requirements belong to the specific product configuration.

## Project questions

### Which protection functions were included?

The portfolio covers earth leakage protection and a combined switch for under-voltage, over-voltage, over-current and earth leakage. It does not specify trip thresholds or certification ratings.
