What is the importance of the 30 mA sensitivity rating?


A sensitivity rating of 30 mA is crucial for protecting against electrocution and enhancing safety by detecting low-level earth faults. This rating can effectively prevent severe electrical shocks and potential fire hazards.

How does the toggle switch improve the usability of this device?


The toggle switch offers a straightforward method for resetting the RCCB after a trip, ensuring quick restoration of power. This allows users to manage electrical systems more efficiently, particularly in high-demand scenarios.

What types of circuits can benefit from this RCCB?


This RCCB is versatile and can protect circuits in residential, commercial, and industrial settings. It is particularly advantageous in areas where water or moisture increases the risk of electrical faults.

How does the short-time delayed feature function in practical applications?


This feature prevents unnecessary tripping during temporary overload conditions, allowing the circuit to stabilise before automatically resetting. This is particularly beneficial in environments with fluctuating loads.

Can this RCCB be used with various cable sizes?


Yes, it accommodates a range of conductor cross-sections from 0.75 mm² to 35 mm² for both solid and stranded cable types, making it adaptable for various installation needs.
