A high-speed circuit breaker based on an electromechanical relay with a constant magnet and current sensor having high-sensitive magnetoresistor relates to electrical engineering and electronics and intended for switching on/off DC circuits under load, and automatic switching off in case of overloads or short circuits. It is used mainly for protection of equipment and DC circuits of traction substations of electrified railways, underground, mini-underground, high-speed trams, automated rail roads, trolley buses, monorail railway and others. |
