Prevent all kinds of electrical accidents with earth leakage relays that protect safety and reliability.

■ Overview
Safety management of electrical equipment is extremely important in modern industrial facilities and office buildings. Earth leakage relays (ELRs) are products that play a central role in these safety measures. By quickly shutting off the power in the event of an electrical leak, the risk of personal injury and fire is greatly reduced. This product has become an indispensable safety device, especially in modern facility management that uses a lot of electricity.

■Features
・Highly sensitive earth leakage detection: Using the latest sensor technology, even the smallest electric leakage can be detected quickly.
・Various range of applications: We offer a wide range of models to accommodate various environments such as residences, office buildings, and factories.
・Easy installation and maintenance: Designed for easy installation and minimal regular maintenance.
・Highly reliable performance: With years of experience and advanced technology, we provide stable performance over a long period of time.

■Specifications
Earth leakage relays have various specifications depending on various voltage levels and installation environments. Generally, you want a model with excellent sensitivity, shut-off time, and durability. Specialized models are also available for use in specific industrial applications and environmental conditions. By checking these specifications, you will be able to select the most suitable product for each facility and application.

When selecting an earth leakage relay, it is important to select the appropriate model according to the installation environment, expected risks, and type of electrical equipment. At our company, we propose the most suitable earth leakage relay according to the needs of our customers. Please consider our earth leakage relays to improve safety management and prevent electrical accidents.
