The Coil Trip unit operates on a direct current (DC) voltage of 24 volts. This voltage is supplied to the coil to energize the trip mechanism. The steel coil, wound with copper wire, is a part of the trip unit. When energized, it generates a magnetic field, which is used to actuate the trip mechanism and open the circuit breaker contacts. NT and NW frames are specific frame sizes or categories that define the physical dimensions and current-carrying capabilities of the circuit breaker.Attributes:• Ensure the safety and protection of the electrical unit• Prevent unintentional tripping, such as adjustable time delays to account for inrush currents during motor startup• Ensure that the circuit breaker trips when necessary to protect the electrical system and connected loadsApplications:The Coil Trip is used in the circuit breaker to generate a magnetic field, which, in turn, actuates a trip mechanism to open the circuit breaker contacts when overcurrent or short-circuit conditions are detected.
