These relays operate by monitoring the current balance between the phase and neutral wire, and upon detecting a leak, they quickly respond and cut off the power supply, ensuring user safety. The utility model discloses an inside electric leakage alarm device of block terminal, including block terminal box and electric leakage alarm, electric leakage alarm installs on the block terminal box, is provided with protection subassembly, installation component and light warning subassembly of. Leakage protection device, also known as leakage protector, refers to a device that can automatically disconnect the circuit or send out an alarm signal when the leakage current in the protected circuit reaches a predetermined value under certain conditions. It is a general term for leakage. Internal Structure: The core internal components of this fire safety and security distribution box are configured to prioritize safety and monitoring needs. For the power distribution section, it is equipped with miniature circuit breakers with leakage protection, which can simultaneously provide. Eaton leakage relays are modern and reliable devices designed to protect electrical systems from leaks that can cause electric shocks, fires, and other hazards. And it has the function of overload short circuit protection.
