
Distributed busbar protection in incoming feeders and busbar protection interlock in outgoing
feeders (activated if current setting IZS>> is exceeded).

Closing interlocks for any selectable criteria.

Distributed multistage smart load (SCO) and load restoration (Reclose the circuit breaker after
tripping ANSI 79 - SPZ/SCO) automation
and/or two-stage SCO automation, centralized with
SPZ/SCO.

Capability to operate together with other substation automation solutions – start-up of a local
circuit-breaker failure protection (LRW) with a separated contact-type input.

Operation together with current transformers with the rated secondary current of 1 A or 5 A.

Support of the following configurations of busbars disconnectors:
a) single-type busbars:
- disconnectors in conventional configurations,
- three-position disconnectors, including disconnector-earthing switch,
- switchgear w/ withdrawable circuit-breaker segment,
b) double-type busbars:
- two systems of disconnectors,
- disconnector-earthing switch and disconnector.

Control of circuit-breaker and electric driving mechanism of bay disconnectors (depending on
the current APPLICATION version, the control is operated via keyboard using three additional
buttons; operation together with a conventional controller is optional).

Summation of braking currents (switched Amperes) by the circuit-breaker in four adjustable
ranges.

Interlock against “surging”, i.e. multiple closing operations of the circuit-breaker during short-
circuit.

Switch-off and switch-on heavy contacts relays (type SR6 – number of relays depending on
module configuration), dedicated to operate together with circuit-breaker coils (in emergency,
the contact can break a circuit with a typical breaker coil resistance of 185 Ohm without risk of
damage. The number of such emergency operations is up to 300.

Make-contact SPST NO and change-over relays SPDT (number depending on module
configuration), used to fulfill additional functions.

Free allocation of digital inputs (physical terminals and computer inputs) and relay outputs to
selected functions of the application.

Unipolar and bipolar digital inputs (number depending on module configuration), including
inputs with a programmable sensitivity threshold setting >20/>50 V DC and bipolar inputs (with
220/24 V DC input resistance to be readjusted by program).
All logic inputs and outputs are programmable , independently of whether they are
described in external wiring diagrams as dedicated to a specific function or not.

Visual signaling on the LCD screen ( QVGA color or alphanumeric – 2x16 characters),
programmable LEDs (monochromatic or two-color) – depending on the operator panel type,
two diodes to indicate the circuit-breaker status (for configurations w/o graphic display), diode
to indicate proper device operation, diode AW to indicate emergency shutdown, diode UP to
indicate bay supervision request and diodes to indicate activity of interfaces, and remote control
interlock (BTS) diodes.
