Earth Leakage Relay
Our Earth Leakage Relay (model ECT-35D) is a compact, high-performance protective device designed to detect and respond to ground-fault currents. It features a built-in core-balanced current transformer (CBCT) with a 35 mm inner diameter, eliminating the need for an external CT. With a detection range of 30 mA to 3 A AC, it offers precise earth-leakage sensing, user-programmable trip delay, and reliable relay operation for industrial protection systems.
Applications
The ECT-35D is ideal for a wide range of industrial and commercial scenarios:
• Motor control centers and MCC panels — protects against earth faults.
• Distribution boards in power control centers.
• Control & relay panels for secure fault monitoring.
• DG set panels and energy management systems.
• Any setup requiring ground-fault protection without bulky external
transformers.
Construction & Design
Designed for reliable industrial use, the relay employs a built-in CBCT for compactness and ease of wiring. Internal electronics include precise signal conditioning, microcontroller-based trip logic, and LED display driving. The robust relay output ensures clean switching. The unit supports front-panel user interaction with Test and Reset keys, making field testing and maintenance straightforward. The chassis is built for panel mounting with a small footprint, saving space in control panels.
