Supply shunt release series owe the series of voltage release series auxiliary contact alarm contact series auxiliary alarm contact series electric operation Organization CDM3 series electric operating mechanism CD series of manual operating mechanism series plug-in device series board wiring series NS plastic shell breaker attachment series DW45 Intelligent Circuit Breaker Accessories Series CM2 breaker attachment series CM1 leakage circuit breakers and accessories series, cm1, cm2 tm30 (nf30), ??abb (hsm1) ns, totg, ??dz20 such as molded case circuit breaker series of attachments. 

 First, an overview 
 The shunt trip is installed internally in the circuit breaker trip coil attachment, connected to the rated working voltage of the circuit breaker trip gate for the remote control circuit breaker tripping Tripping, also commonly used in fire protection system . A result of the coil is energized, the excitation and switch the action of the sub-gate, so that the coil is called the shunt coil, is one of the circuit breaker internal accessories. 
 Second, the relevant parameters 
 Rated operating voltage range: 85% ~ 110% of rated voltage Ue. 
 Intermediate relay into a form of control in order to avoid fire host power capacity is too small to cause does not release phenomenon when used in fire protection system is recommended. 
 The wiring diagram is as follows: 

 Use 
 Shunt release is used for remote control circuit breaker. The release of the instantaneous working.
