This EAL-1 series product combines the functions of a Residual Current Device (RCD) and overload protection, delivering comprehensive safety for your circuits. With a rated voltage of 380 V and frequency of 50/60 Hz, this RCBO is designed to withstand a rated short-circuit capacity of up to 6000 A. Its mechanical service life is 10,000 cycles and its electrical service life reaches 4,000 cycles, ensuring durability and reliability. Additionally, the device features DIN-rail mounting, facilitating installation in electrical panels. This RCBO is CE-marked and complies with IEC/EN 61009-1 and GB 16917.1 standards, providing confidence in its performance. Its primary functions include protection against overloads, short circuits, and residual current leakage, making it an ideal choice to prevent electrical fires and ensure user safety. Choosing the Type B 2-in-1 RCD Circuit Breaker means selecting a versatile and effective solution for your electrical protection needs. Prioritize safety and protect your circuits with this reliable device. RCD vs. RCBO Difference #1: Operation The operating principle of an RCD involves monitoring the current flowing through a circuit. If an imbalance is detected, it trips and disconnects the power supply. An RCBO also monitors current flow through a circuit in the same manner as an RCD, using a similar mechanism. However, it will trip not only upon detecting an imbalance but also upon detecting an overload or short circuit. Therefore, its operation differs slightly from that of an RCD. RCD vs. RCBO Difference #2: Function The primary function of a Residual Current Device (RCD) is to protect people from electric shock caused by residual currents or earth faults. An RCBO has two functions: first, protecting people from electric shock caused by residual currents or earth faults; second, preventing electrical fires by rapidly cutting off power before serious damage occurs. This distinction arises because an RCBO incorporates built-in circuit breaker functionality, whereas an RCD does not. This makes the RCBO more suitable for applications requiring enhanced protection—such as circuits with higher fire-risk potential. RCD vs. RCBO Difference #3: Versatility An RCD can only be used for protection against shocks caused by earth faults. It cannot be used for overcurrent protection. To protect a circuit against overcurrent, it must be used in combination with an MCB or another overcurrent protective device. An RCBO, by contrast, is far more versatile: it can not only protect against shocks caused by earth faults but also selectively protect circuits against overcurrent conditions. **Price excluding VAT**
