www.sigmaelektrik.com 14 Thermal Magnetic Trip Thermal magnetic breakers are tripped by the bimetal heated by the load current. Bimetals are responsive to the heat emitted by the current flow so as to cause the operating mechanism to allow a long time delay on light overloads. Thermal magnetic breakers are also tripped through the use of electro magnet. This provides an instantaneaus tripping action when the current over the predetermined value flows.

www.sigmaelektrik.com 15 Current Limiting The assumed fault current Isc is the short-circuit current Isc that would flow, if there were no limitation, at the point of the installation where circuit-breaker is placed. Since the fault current is eliminated in less than one halfperiod, only the first peak current (asymmetrical peak) need be considered. This is a function of the installation fault cos. An electromagnetic repulsive force is where the forced works between a current of he movable conductor and current (i) in the reversed direction of the fixed conductor. This is an improvement of the...

www.sigmaelektrik.com 20 Intelligent Unit for U1600 A MCCB's Electronic trip units are devices which guarantee a system of protection based on microprocessor electronics.In comparison with thermomagnetic trip units, they allow a mora precise seting both in therms of trip times as well as in terms of current thresholds in order to meet better the installation requirements. Electronic intelligent trip units, which can be mounted on U1600 type MCCB’s implement thi following protection functions. Protection against overloads (long time delay trip function) is identified by Functional L If the falut...
