SEOUL, South Korea, Nov. 11, 2026 /CourierPR/ -- JOAM INNOTECH CO., LTD, a Korean company specializing in electrical safety, has taken a significant step in advancing its product lineup by developing an integrated protection PCB module that combines overvoltage, overcurrent, and earth-leakage protection in a single unit. This innovation aims to strengthen the company's presence in the global electrical safety market.
JOAM INNOTECH has been mass-producing and supplying overcurrent protection PCBs since late 2024, a move that has allowed the company to build up its manufacturing capabilities. In April 2026, it filed a Korean patent application for its overvoltage protection technology, marking a pivotal moment in its technological advancement. The company then proceeded to develop prototypes of the integrated protection module and conducted initial performance tests in May.
The new module is designed to detect abnormal conditions in the power system, such as sustained high voltage, overcurrent, or earth leakage, and trigger the breaker's trip mechanism in response. Unlike conventional protection methods that only suppress momentary voltage surges, the module has enhanced overvoltage detection capabilities, ensuring it responds to continuously supplied abnormally high voltage.
A key advantage of the integrated protection module is its compatibility with existing compact earth-leakage circuit breaker designs. The module was designed around standard PCB dimensions, mounting methods, and trip coil connections, allowing manufacturers to add it without external protection devices or major mechanical redesigns. This feature enables circuit breaker and power strip manufacturers to expand protection features and set their products apart while maintaining their existing product designs.
JOAM INNOTECH plans to run application tests in finished products, verify reliability, and set mass-production inspection standards to prepare for commercialization. The company's phased approach to development and commercialization underscores its commitment to innovation and market expansion.
