What is the significance of the earth leakage protection class?


The earth leakage protection class, Type A, is important as it provides a comprehensive response to different fault conditions, ensuring the safety of the connected electrical systems.

How does the time delay feature benefit its operation?


The time delay feature allows users to set adjustable time frames to delay the tripping process, which can prevent nuisance tripping during transient conditions or in systems with inrush currents.

What electrical supply ratings does it support?


It supports a rated supply voltage of 380 to 415V AC at 50/60Hz, which is within the standard range for many industrial applications, thus ensuring compatibility with existing electrical systems.

What type of monitoring does the relay perform continuously?


It continuously monitors earth fault currents, providing real-time feedback for immediate action if thresholds are reached, which enhances overall system safety and reliability.

How does the tamper-proof feature enhance functionality?


The tamper-proof feature, protected by a sealable cover, prevents unauthorised adjustments, ensuring settings remain consistent and reliable for optimal operation.
