![]() CharacteristicsĬircuit Breaker consists of electromechanical switch and a relay in a single box. The following table shows the main differences between Isolators, Disconnectors and Circuit Breakers. Related Post: Main Difference between Fuse and Circuit Breakerĭifferences between Circuit Breaker and Isolator / Disconnector.A relay inside the circuit breaker sense the errors signal and sends to the mechanical switch which make and close the contacts. It also capable to operate automatically, manually or by remote control in normal and faulty conditions. ![]() It break the circuit in case of fault conditions like short circuit and overload. Related Post: Difference Between Relay and Circuit BreakerĪ Circuit Breaker is a protective device used to control the flow of current same like a fuse. There may a physical and construction difference between Switch Disconnectors, Load Switches, Disconnectors as Isolating Switches but the function is almost same.Keep in mind that isolator or disconnector should not open when the current is flowing through it.HV/MV Switch Disconnectors And Isolators are used where power installations exceeding 1 kV AC (IEC- 61936-1). Switch Disconnectors are used in MV installation nowadays. HV and MV Switch Disconnectors and Isolators are used in high voltage equipment such as transformer, substation etc. Isolator blocks the DC current and allow the AC current to flow through it (same like a capacitor). It is used where we need to disconnect a portion of the circuit in case of faults from the main power supply for maintenance purposes. Characteristics of Switch DisconnectorsĪs the name suggests, An Isolator or Disconnector is an isolating or disconnecting switch which disconnects or isolate the whole or a specific part of the circuit.Different Characteristic of Isolator, Switch Disconnector and Circuit Breaker.Differences between Circuit Breaker and Isolator / Disconnector.
