FAQs
1. What is a 100A 300mA RCCB used for?
Ans: A 100A 300mA RCCB is primarily used for fire protection & leakage current detection in high-load electrical systems, helping prevent insulation-related fire hazards.
2. What does 300mA sensitivity mean?
Ans: A 300mA sensitivity means the RCCB will trip when leakage current exceeds 300 milliamperes, providing effective protection against leakage-related fire risks.
3. How is a 300mA RCCB different from a 30mA RCCB?
Ans: A 300mA RCCB is mainly designed for fire protection & upstream circuit protection, whereas a 30mA RCCB is intended for personal protection against electric shock.
4. Why use a Double Pole (DP) RCCB?
Ans: A Double Pole RCCB disconnects both live & neutral conductors simultaneously, ensuring complete circuit isolation & improved safety.
5. What is the difference between an RCCB & an MCB?
Ans: An RCCB protects against earth leakage currents, while an MCB protects against overload & short-circuit conditions.
6. 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.
7. Where is this RCCB commonly installed?
Ans: It is commonly installed in industrial plants, commercial buildings, main distribution boards, high-load electrical circuits, upstream protection systems, & fire safety installations requiring leakage monitoring.
8. How is the RCCB mounted?
