Theory:Numerical Relay Usage:Protective Size:Other Protect Feature:Sealed Contact Load:High Power
Current relay is the most commonly used component in power system relay protection. The detection object of the current relay is the change of the current of the circuit or main electrical components. When the current exceeds (or is below) a certain setting value, the relay acts to complete the relay control and protection.
It help extend battery life.
Prevents primary battery discharge.
Made of water resistant black phenolic plastic.
Cold Load Settings
Circuit Breaker Trip Counter and Timer
Fault, event and waveform records
The current relay has the advantages of simple wiring, fast and reliable operation, convenient maintenance, and long service life. As a protection element, it is widely used in overload protection and short circuit protection circuits of motors, transformers and transmission lines.
structure type Current relay is divided into: electromagnetic current relay, static current relay.
Installation method The current relay is divided into: rail current relay, fixed current relay.
Current action Current relays are divided into: overcurrent relays and undercurrent relays.
Time curve Current relays are divided into: time-limited current relays and inverse time-limited current relays.
Use Current relays are divided into: small control relays, secondary circuit protection relays.
Used as a starting element in overload and short-circuit protection devices for generators, transformers and transmission lines.
