Fault Protection:

- Overvoltage Trip: Activates relays when voltage exceeds set thresholds (e.g., 110% of rated voltage).
- Undervoltage Trip: Triggers alarms/tripping if voltage drops below 85% of rated levels.
- Phase Loss Detection: Identifies missing phases to prevent equipment damage.
- Voltage Unbalance Alerts: Flags deviations >5% between phases .
  Modular Integration:
  Part of ABB’s REG216 protection system, the 216EA41b interfaces with other modules (e.g., 216GD61a relay modules, 216GW61 input converters) for comprehensive generator/transformer protection. Its plug-and-play design simplifies system expansion .

The ABB 216EA41b is a robust voltage monitoring module that combines precision measurement with reliable fault protection, making it essential for industrial systems where voltage stability is paramount. Its modular design, wide compatibility, and ease of integration with ABB’s automation portfolio ensure seamless deployment in power generation, manufacturing, and renewable energy sectors.
