Signaling contacts
34) Three changeover contacts for electrical signaling of circuit-breaker open 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).
35) One changeover contact for electrical signaling of circuit-breaker open due to tripping of the
thermal magnetic electronic trip unit (only for voltages up to 250V).
36) Two changeover contacts 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).
37) 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
voltage up to 400V).
38) Two changeover contacts for electrical signaling of circuit-breaker open or closed (only for
voltage up to 400V).
