Abstract

Unidad de disyuntor de supresión de corrientes para protección de motores de inducción. Una unidad de disyuntor y de supresión de corriente en una caja moldeada, que protege un motor eléctrico sin disparo de conmutación durante la inversión de la corriente del motor. La unidad de disparo de conmutación del disyuntor proporciona la protección de sobrecorriente de larga duración, corta duración e instantánea, contra corrientes de sobrecarga anormal y de cortocircuito de baja intensidad dentro del circuito protegido. La unidad de supresión de corriente suprime rápidamente las corrientes de cortocircuito de alta intensidad hasta que el disyuntor responde para aislar el equipo protegido.Current suppression circuit breaker unit for protection of induction motors. A current suppression and circuit breaker unit in a molded case, which protects an electric motor without switching trip during reversal of motor current. The circuit breaker commutation trip unit provides the protection of long duration, short duration and instantaneous, against abnormal overload currents and low current short circuit inside the protected circuit. The current suppression unit quickly suppresses high current short circuit currents until the circuit breaker responds to isolate protected equipment.
