## Summary description

The Legrand 026088 is a high-precision residual current relay designed for electrical circuit protection. It features an adjustable sensitivity range of 0.03A to 30A and a time delay setting from 0 to 15 seconds. This professional-grade component ensures reliable monitoring and safety in industrial and commercial electrical installations, effectively detecting leakage currents to prevent faults.

## Long description

The Legrand 026088 residual current relay is a professional-grade device engineered for precise monitoring and protection of electrical circuits. It is designed to detect leakage currents and, when integrated with a shunt trip or undervoltage release, provides a reliable command to trip a molded case circuit breaker or switch. This unit is built for industrial and commercial environments where safety and fault prevention are critical.
Advantages
This relay offers exceptional flexibility through its wide range of adjustable sensitivity settings and time delays, allowing it to be tailored to specific installation requirements. The device features a clear visual interface with multiple LEDs that indicate energization status, insulation current levels, and potential connection faults. Its compact design for DIN rail mounting ensures easy integration into existing electrical panels, while the sealable window provides added security against unauthorized adjustments.
Suitable for
Industrial electrical distribution systems
Commercial building power management
Protection of electrical circuits against earth leakage faults
Integration with MCCBs or switches for automated safety tripping
This relay may not be suitable for residential applications where standard compact RCDs are sufficient, as it is designed for complex industrial setups requiring external coils and specific tripping coordination. It is also not intended for use without compatible external coils or appropriate circuit breaker accessories.
Key specifications
Sensitivity range: 0.03A to 30A (depending on coil diameter)
Time delay settings: 0 to 5 seconds
Supply voltage: 230/240 V at 50/60 Hz
Mounting: Symmetrical DIN rail
Width: 2 modules
Visual indicators: Green LED for power, yellow LEDs for insulation current, red LED for fault/connection status
Installation should be performed by a qualified professional. The relay is clipped onto a standard symmetrical rail. It must be connected to a compatible external coil (diameters ranging from 35mm to 300mm) and linked to a shunt trip or undervoltage release mechanism on the circuit breaker. Ensure all wiring connections between the coils and the relay are secure to prevent false fault indications.
What to consider before purchase
Compatibility with your existing circuit breaker or switch mechanism
Required coil diameter for your specific cable configuration
Space availability on the DIN rail within the distribution board
The need for a shunt trip or undervoltage release accessory
Usage recommendations: Regularly check the LED indicators to ensure the system is energized and operating within normal insulation parameters. If the red LED flashes, immediately inspect the connections between the coils and the relay to ensure system integrity.
