Square d brand electronic trip circuit breakers use the micrologic tripping system which includes current sensors a microprocessor based trip unit and a tripping solenoid.
In addition to this electronic tripping units offer more tripping criteria which are not feasible with electromechanical releases.
Thermal magnetic molded case circuit breakers are the most common overcurrent protection devices. Thermal magnetic circuit breakers use bimetals and electromagnetic assemblies to provide overcurrent protection. Their primary functions are to provide a means to manually open a circuit and automatically open a circuit under overload or short circuit conditions. The catch reporting piece of safis is etrips.
