Earth Leakage Breakers (Low Capacity)（Ampere frame AF：400AF or higher）

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.
