FAQs
1. What is a 25A RCCB used for?
Ans: A 25A RCCB is used to protect electrical circuits & users from earth leakage faults, electric shocks, & fire hazards caused by leakage currents.
2. What does 30mA sensitivity mean?
Ans: A 30mA sensitivity means the RCCB will trip when leakage current exceeds 30 milliamperes, providing effective protection against electric shock hazards.
3. Why use a Double Pole (DP) RCCB?
Ans: A Double Pole RCCB disconnects both live & neutral conductors simultaneously, ensuring complete circuit isolation & improved safety.
4. What is the difference between an RCCB & an MCB?
Ans: An RCCB protects against earth leakage currents & electric shock, while an MCB protects against overload & short-circuit conditions.
5. Does the RCCB protect against overloads?
Ans: No, an RCCB only protects against leakage currents. Overload & short-circuit protection require an MCB or RCBO in combination with the RCCB.
6. Where is this RCCB commonly installed?
Ans: It is commonly installed in residential homes, offices, commercial buildings, retail outlets, & light industrial electrical systems requiring leakage protection.
7. How is the RCCB mounted?
Ans: The RCCB is designed for easy installation on standard DIN rails inside distribution boards & electrical panels.
8. Why is periodic testing important?
Ans: Regular testing using the built-in test button helps verify proper RCCB operation & ensures continued protection against leakage faults & electric shock hazards.
