Advanced neutral mechanism
Efficient Earth Leakage ProtectionOur RCCB units provide rapid and reliable disconnection of faulty circuits, activating within 300 ms when detecting residual currents of 30mA, 100mA, or 300mA. This critical function minimizes the risk of electrical shocks and fire hazards, ensuring safety for both users and connected equipment in homes and industries.
Versatile and Robust DesignManufactured with high-strength flame-retardant plastic, the RCCB offers exceptional durability. It is built to resist humidity up to 95% RH (non-condensing) and operates smoothly within a wide temperature range. The ON/OFF visual indicator and dual mounting orientation (vertical/horizontal) enhance user convenience.
Universal Application and Easy InstallationSupporting both single and three-phase supplies (230/415V AC) with current ratings of 25A, 40A, and 63A, the RCCB is adaptable to a range of electrical systems. DIN rail mounting and generous terminal capacity (up to 25 mm) simplify the installation process for electricians and installers alike.
FAQs of Residual Current Circuit Breaker (RCCB):
Q: How does the RCCB enhance electrical safety in my installation?
A: The RCCB continuously monitors circuit currents and disconnects the circuit in under 300 ms if it detects residual leakage above the set threshold (30mA, 100mA, or 300mA). This swift action prevents electric shock and reduces the likelihood of electrical fires caused by earth leakage.
Q: What are the installation options for this RCCB?
A: This RCCB can be installed either vertically or horizontally and is designed for straightforward DIN rail mounting. Its terminal capacity supports cable sizes up to 25 mm, making it suitable for a variety of residential, commercial, or industrial panels.
Q: When should I choose a 2-pole or 4-pole version of the RCCB?
A: The 2-pole version is ideal for single-phase circuits, while the 4-pole RCCB is designed for three-phase systems. Selection depends on the phase configuration and specific application requirements in your installation.
Q: What types of electrical currents does this RCCB detect?
A: This RCCB is Type AC, meaning it is sensitive to standard alternating current (AC) leakage. It provides reliable protection against common forms of earth leakage currents encountered in homes and businesses.
Q: Where can I purchase this RCCB in India?
A: You can obtain this RCCB from authorized distributors, manufacturers, suppliers, traders, and wholesalers throughout India. Look for reputable vendors who provide genuine products and after-sales service support.
Q: What is the rated current and voltage supported by this RCCB?
A: The RCCB is available with rated currents of 25A, 40A, and 63A, and operates at voltages of 230V for single-phase and 415V for three-phase systems, both at a frequency of 50 Hz.
Q: Is the RCCB suitable for high-humidity or harsh environments?
A: Yes, the RCCBs flame-retardant, high-strength plastic housing offers IP20 protection and is built to resist up to 95% relative humidity (non-condensing), making it suitable for varied and challenging installation environments.
