MCGG 22D1CB1003B GEC Alsthom MiCOM Phase & Earth Overcurrent Protection Relay

Description:

• Genuine GEC Alsthom (now GE Grid Solutions) MCGG phase and earth overcurrent protection relay
• Designed to provide reliable phase overcurrent and earth fault protection for electrical distribution and power systems
• Suitable for protecting overhead lines, underground feeders, transformers, generators, motors, and neutral earthing resistor circuits
• Combines inverse definite minimum time (IDMT) and definite time overcurrent protection in a compact draw-out relay
• Built-in instantaneous high-set overcurrent element can be enabled or disabled to suit the application
• Supports multiple time-current characteristics including Standard Inverse, Very Inverse, Extremely Inverse, and Long-Time Earth Fault
• Plug-in draw-out case simplifies installation, commissioning, testing, and maintenance
• Ideal for substations, switchgear, utility distribution networks, industrial power systems, and electrical protection panels
• Part of the proven MIDOS MCGG relay family used worldwide in medium- and high-voltage protection systems.
