Shunt trip
Rated control power voltage of shunt trip is AC 23oV (SOI-Iz or 60Hz) or 400V; it should be e- nsured that ;hunt trip can used to open the trip ofcircuit breaker at all operation condition of the breaker when power voltage is eyual to any of 70%-110% control power voltage The start power for the coil of shunt trip shall not be less rhea 140VA
Auxiliary contacts and alarm contacts
Single break transition contact elements shall be adopted for auxiliary contacts and alarm contacts of auxiliary circuit: the electric structure is linked togetlret
