● Tripping of the ETU by the residual current module Rc
● Tripping of the shunt or undervoltage release
● Mechanical tripping by PUSH TO TRIP pushbutton

The circuit breaker can only be reclosed once the mechanical signaling button for "ETU
tripped" (reset) has been operated or the circuit breaker has been reset to its normal
operating position manually or by means of the remote reset magnet RR.
The trip alarm switch (TAS) can only be used for 3VA27 molded case circuit breakers with
