Duty cycle of circuit breaker
WebDuty cycle is well defined as D C = T h i g h T p e r i o d Here T h i g h is the time your signal is high out of the total period of length T p e r i o d . In percents it will be D C % = 100 T h i g h T p e r i o d So D C % = 0 implies T h i g h = 0, i.e. the signal is always low. WebMar 25, 2024 · Two-pole circuit-breakers for use in single-phase systems and application at frequencies lower than 50 Hz are subject to agreement between manufacturer and user. This standard is also applicable to the operating devices of circuit-breakers and to their auxiliary equipment.
