Product Info

Electrical leakage poses serious risks in industrial plants, commercial buildings, and offices. Earth Leakage Relays (ELRs) are designed to detect small leakage currents and immediately cut off the power supply, preventing damage to equipment and protecting human lives.

With high sensitivity and fast response, ELRs are a critical safety component for any environment where electrical reliability is vital. They help comply with safety standards and reduce the risk of fire and injury due to ground faults.

Hitachi Asia (Thailand) Co., Ltd., based in Bangkok, offers fast and reliable service throughout Southeast Asia, including Indonesia, Malaysia, Myanmar, the Philippines, Singapore, Thailand, and Vietnam.
