GIC Earth Leakage Relays

GIC Earth Leakage Relays provide dependable ground fault detection and protection for electrical systems, ensuring personnel safety and preventing equipment damage caused by insulation failure or current leakage to earth. Designed for industrial, commercial, and process control panels, these relays offer adjustable sensitivity, fast trip response, and clear fault indication.

🔧 Technical Highlights:

• Function: Monitors residual current via external core balance current transformer (CBCT) to detect earth leakage or ground faults.
• Sensitivity Range: Adjustable from 30 mA to 30 A (model dependent).
• Trip Delay: Selectable time delay from instantaneous to several seconds for coordination with system protection.
• Supply Voltage: Wide operating range, typically 24 V DC to 240 V AC/DC depending on model.
• Output Contacts: SPCO or DPCO relay outputs for alarm or tripping circuit integration.
• Indication: LED indicators for power, trip, and fault reset status.
• Mounting: 35 mm DIN rail or panel mount housing.
• Compliance: CE and RoHS; conforms to IEC/EN 60947 standards for industrial use.

✅ Benefits:

• Protects equipment and personnel from dangerous leakage currents.
• Adjustable trip sensitivity and delay for flexible coordination.
• Compact DIN rail design simplifies integration into existing panels.
• Fast and reliable detection of insulation and wiring faults.
• Ideal for preventive maintenance and enhanced electrical safety compliance.

🚀 Applications:

• Motor control centres and switchgear panels.
• Industrial automation and process machinery.
• Building management and HVAC systems.
• Power distribution and energy monitoring panels.
• Renewable energy and generator protection circuits.

GIC earth leakage relays deliver precise, configurable ground fault protection to safeguard operators, motors, and electrical systems from insulation failure and residual current hazards.

FAQs

• Q: How does an earth leakage relay work?
  A: It uses a core balance current transformer (CBCT) to measure the imbalance between phase and neutral currents. Any difference indicates leakage to earth, triggering the relay output.
• Q: What sensitivity should I choose for my application?
  A: For personnel protection, use 30–300 mA settings; for equipment and system protection, use higher settings up to several amperes depending on load and installation conditions.
