Earth Leakage Breakers (Low Capacity)(Representative Standard:CE)

Earth Leakage Circuit Breakers (ELCB), also known as an earth leakage switch or earth leakage protector, is an electrical safety device that detects and protects against electrical shock hazards caused by leakage current. When selecting an Earth Leakage Circuit Breaker (ELCB), it is crucial to consider factors such as Ampere frame, Number of Poles, Rate Current, Rate Operating, Voltage, Mounting Method (e.g., DIN rail mount, Fasten with screws, and etc.), and Size (height , width and depth). These considerations are vital for ensuring the production of high-quality products. We highly recommend reputable brands like MITSUBISHI , FUJI ELECTRIC , and NITTO KOGYO
Take advantage of the convenience of FREE SHIPPING and NO MINIMUM ORDER on the Earth Leakage Circuit Breaker (ELCB). If you have any doubts or require assistance in choosing the right product, our experts are readily available to provide advice and guidance.

                                                              FAQ Earth Leakage Breakers (Low Capacity)

                                                              Question: What is the function and capacity of an Earth Leakage Circuit Breaker (ELCB)?
                                                              Answer: An Earth Leakage Circuit Breaker (ELCB) is a crucial safety device in electrical installations. Its primary function is to protect individuals from electric shock by automatically disconnecting the power supply when a fault occurs. ELCBs are designed to detect imbalances in the current flowing between live and neutral conductors. When a leakage current exceeds its rated value (typically 30mA or 100mA), the ELCB trips, interrupting the circuit and preventing potentially fatal injuries. This rapid response time ensures immediate protection against electric shock hazards.
                                                              Question: What are the typical reasons for an ELCB to trip, and how does one troubleshoot it?
                                                              Answer: ELCB Tripping: Reasons and Troubleshooting
                                                              Common Reasons:
                                                              1.Earth Leakage: Current flows through unintended path (faulty appliance, wiring, water).
                                                              2.Circuit Overload: Current exceeds ELCB's rating (too many appliances).
                                                              3.Nuisance Trips: High sensitivity, electrical noise, power surges.
                                                              4.Troubleshooting:

                                                              Identify affected circuit and appliances.
                                                              1.Turn off all appliances and reset ELCB.
                                                              2.Switch on appliances one by one to find the culprit.
                                                              3.Repair/replace faulty appliance or fix wiring.
                                                              4.Test ELCB again with all appliances on.
                                                              Question: How does one determine the appropriate tripping capacity and minimum rating for an ELCB?
                                                              Answer: 1. Tripping Capacity: This depends on potential fault currents and the maximum allowable leakage. Factors include:
                                                              - Fault Current Loop Impedance: The resistance of the path the fault current takes to Earth, influencing how quickly the ELCB trips.
                                                              - Maximum Earth Fault Current: The highest current the ELCB should allow to flow before tripping, typically 30mA or 100mA.

                                                              2.Minimum Current Rating: This is based on the circuit's maximum current demand and needs to be equal to or higher than the expected circuit load. Factors include:
                                                              - Circuit Load: The total current drawn by all appliances connected to the circuit.
                                                              - Diversity Factor: Considers that all appliances won't operate at maximum load simultaneously.
                                                              Question: What are the standard sizes of earth leakage, and how do you calculate the correct size for your needs?
                                                              Answer: Earth leakage circuit breakers (ELCBs) come in a range of standard sizes, typically specified by their rated current (In) and tripping sensitivity (IΔn). Common sizes include:
                                                              1.Current (In): 16A, 20A, 25A, 32A, 40A, 63A, 80A, 100A, 125A
                                                              2.Sensitivity (IΔn): 30mA, 100mA, 300mA

                                                              Choosing the correct size for your needs involves two main considerations:
                                                              1.Maximum Current Demand: Calculate the total current drawn by all appliances connected to the circuit.
                                                              2.Tripping Sensitivity: Based on safety requirements and potential fault scenarios.

                                                              Example: Sum all appliance currents:
                                                              Appliance A: 300W (1.3A)
                                                              Appliance B: 500W (2.17A)
                                                              Total current demand: 3.47A
                                                              This means you need an ELCB with a rated current (In) equal to or greater than 3.47A.
                                                              Question: How do you measure earth leakage current, and what is the acceptable range for safety standards?
                                                              Answer: Measuring earth leakage current requires a specialized instrument called an earth leakage clamp meter. It clamps around the earth conductor of the circuit and measures the current flowing through it. Acceptable levels for safety vary depending on regulations and application:
                                                              - IEC 60364-4-42: 30mA maximum for general residential installations.
                                                              - BS 7671: 30mA for most domestic circuits, 100mA for specific situations (e.g., bathrooms).
