Indication contacts
These common-point changeover contacts provide remote circuit-breaker status information.
They can be used forindications, electrical locking, relaying, etc.
They comply with the IEC 60947-5 international standards.
Functions
Breaker-status indications, during normal operation or after a fault
A single type of contact provides all the different indication functions:
OF(ON/OFF) indicates the position of the circuit breaker contacts
SD (trip indication) indicates that the circuit breaker has tripped due to
an overload
a short-circuit
an earth fault (Vigi) or a ground fault (Micrologic 6)
operation of a voltage release
operation of the "push to trip" buttono disconnection when the device is ON.
The SD contact returns to de-energised state when the circuit breaker is reset.
SDE (fault-trip indication) indicates that the circuit breaker has tripped due to:an overload
a short-circuit
an earth fault (Vigi) or a ground fault (Micrologic 6).
The SD contact returns to de-energised state when the circuit breaker is reset.
SDV indicates that the circuit breaker has tripped due to an earth fault, It returns to de-energisecstate when the Vigi addon is reset.All the above auxiliary contacts are also available in "low-level" versions capable of switching verylow loads (e.g. for the control of PLCs or electronic circuits).Rotary-handle position contact for early-make or early-break functions
CAM (early-make or early-break function) contacts indicate the position of the rotary handle.They are used in particular for advanced opening of safety trip devices (early break) or to energisea control device prior to circuit-breaker closing (early make).
Chassis-position contacts
CE/CD (connected/disconnected) contacts are microswitch-type carriage switches forwithdrawable circuit breakers.
