The delay fuses are used for the protection of _____

  • The delay fuses are used for the protection of Motors.
  • Delay fuses are commonly used in electrical systems to protect motors from damage due to overcurrent.
  • These fuses are designed to delay their response to an overcurrent, providing temporary protection to the motor during high starting current conditions.
  • When a motor starts, it draws a large amount of current, which can cause the fuse to blow if it is not a delay fuse.
  • Delay fuses are designed to tolerate this starting current for a short period of time, typically a few seconds, before they open the circuit in the event of a sustained overcurrent.
  • The delay is achieved by using a time-delay element, such as a coil or a bimetallic strip, that heats up gradually when the current flows through it.
