TERASAKI ELECTRIC ANE-1 AME Overcurrent Trip Relay Unit

Overview

The TERASAKI ELECTRIC ANE-1 AME is an overcurrent trip relay unit designed for Terasaki AME series air circuit breakers, widely used in marine and industrial power distribution systems. The TERASAKI ELECTRIC ANE-1 AME serves as the core OCR protection component to detect overload, short-circuit and earth fault currents. It works with current transformers to provide selective protection for generators, main switchboards and feeder circuits. The TERASAKI ELECTRIC ANE-1 AME is a classic spare part for maintenance and retrofit of legacy Terasaki AME ACB systems on vessels and onshore power plants.

Features

The TERASAKI ELECTRIC ANE-1 AME supports adjustable overload and short-circuit protection settings for coordination of power distribution networks. It provides earth fault detection function to protect against leakage faults in the circuit. The TERASAKI ELECTRIC ANE-1 AME has built-in fault indication and test terminals for convenient on-site inspection. It is specially engineered for marine environments with good vibration and humidity resistance. The TERASAKI ELECTRIC ANE-1 AME adopts plug-in installation structure and matches the AME series air circuit breaker perfectly for direct replacement.

Specs

Device Type: Overcurrent trip relay unit Model: TERASAKI ELECTRIC ANE-1 AMEMatching Breaker: Terasaki AME series air circuit breaker (ACB) Protection Functions: Overload protection, short-circuit protection, earth fault protection Signal Source: Current transformer secondary signal Application: Marine switchboard, generator protection, industrial power distribution Installation: Built-in mounting inside AME air circuit breaker Environment: Marine and industrial power distribution cabinet

Principle

The TERASAKI ELECTRIC ANE-1 AME receives secondary current signals from matched current transformers. The internal circuit samples and calculates real-time current values, and compares them with preset protection thresholds. When the current exceeds the set value, the TERASAKI ELECTRIC ANE-1 AME sends trip command to the operating mechanism of the air circuit breaker to isolate the faulty circuit, and keeps fault status indication for maintenance personnel.

Applications

The TERASAKI ELECTRIC ANE-1 AME is used for generator and main busbar protection on marine vessels. It undertakes feeder circuit protection for ship main switchboards and emergency switchboards. The TERASAKI ELECTRIC ANE-1 AME applies to spare replacement and troubleshooting of Terasaki AME air circuit breakers. It also supports protection for industrial power distribution and generator sets in onshore power stations.
