Signaling contacts

31) One changeover contact for electrical signaling of circuit-breaker open or closed and one
changeover contact for electrical signaling of circuit-breaker open due to tripping of the
magnetic, thermal magnetic or electronic trip units, YO, YO1, YO2, YU (tripped position) (only for
voltages up to 250V) (see notes E and I).
32) Two changeover contacts for electrical signaling of circuit-breaker open or closed, two change
over contacts for electrical signaling of circuit-breaker open due to tripping of the magnetic,
thermal magnetic or electronic trip units, YO, YO1, YO2, YU (tripped position) and one
changeover contact for electrical signaling of circuit-breaker open due to tripping of the ther
momagnetic or electronic trip unit (only for voltages up to 250V).
33) Three changeover contacts for electrical signaling of circuit-breaker open or closed and two
changeover contacts for electrical signaling of circuit-breaker open due to tripping of the
magnetic, thermal magnetic or electronic trip units, YO, YO1, YO2, YU (tripped position) (only for
voltages up to 250V).
