CHINT NJYB3 series protection relays, including models NJYB3-4, NJYB3-5, NJYB3-11, and NJYB3-12, are designed to protect electrical equipment by monitoring conditions like voltage.  If the relays detect issues such as overvoltage, undervoltage, or phase problems, they respond by tripping a circuit breaker or triggering an alarm. This helps to prevent damage and maintain the safety of the electrical system.
