Product Description
TERASAKI ESM-1152 Earth Leakage Relay
The TERASAKI ESM-1152 is an electronic earth leakage relay designed to provide reliable protection against earth fault currents in electrical installations. It continuously monitors the system for leakage currents using an associated Zero Phase Current Transformer (ZCT). Featuring adjustable sensitivity (IΔn) and time delay (Δt) settings via front-panel rotary switches, the ESM-1152 allows for precise configuration according to specific protection requirements. Housed in a compact DIN rail mountable enclosure, it is suitable for various industrial and commercial applications, enhancing electrical safety by detecting potentially hazardous earth faults and tripping an associated circuit breaker or contactor. LED indicators provide clear status information for power, pre-alarm (optional), and trip conditions.
