Terasaki Earth Fault Protection Relay (Without 4th CT) for 3-Pole ACB

The Terasaki Adjustable Earth Fault Protection Add-On (w/o 4th CT) is engineered to improve safety and fault protection in low-voltage power distribution systems. Designed specifically for 3-pole Air Circuit Breakers, this add-on detects earth faults by summing phase currents internally, eliminating the need for a separate neutral or fourth CT.

With adjustable earth fault current and time delay settings, this protection module allows precise coordination with upstream and downstream protection devices. It is ideal for main incomers, feeders, generators, and transformer protection, where fast and selective earth fault detection is critical.

Fully compatible with Terasaki ACB electronic trip units, this accessory enhances system reliability, minimizes equipment damage, and reduces the risk of fire or electric shock. Its compact design allows easy integration into existing Terasaki ACB assemblies.
