NettetThe instantaneous overcurrent protection threshold sets the level of short-circuit current at which the circuit breaker trips with no intentional time delay. For MicroLogic 5.0 X, 6.0 X, 7.0 X control units for IEC and UL standards, instantaneous overcurrent protection can be disabled. NettetETI instantaneous-trip circuit breakers are recommended for use in combination motor starters to provide selective short-circuit protection for the motor branch circuit. The adjustable instantaneous-trip feature of the ETI circuit breaker provides for a trip setting slightly above the peak motor-inrush current. With this setting, no delay is intro- play store psiphon
