3.2.9 Auxiliary switch (Code 9)<br />

Standard breaker can be equipped with 3, 5 or 10<br />

isolated, form C, invertible auxiliary contacts (1 NO/NC<br />

each). The movable main arm activates the contacts.<br />

The contacts are wired to 15-pin control terminals: -X4<br />

and -X5, with 5 switches to each terminal [Fig. 21].<br />

Conventional thermal current Ith=10 A. Maximum<br />

electrical ratings for switches are 1 A/230 V for AC15. For<br />

DC13 are 0.5 A/110 V and 0.3 A/220 V.<br />

<br />

ARC CHUTE INDICATOR (Code 17) – a potential free, NO<br />

contact mounted on the sidewall. Locks electrically the<br />

closing drive when arc chute is not installed on [Fig. 15].<br />

3.2.10 Indicators<br />

<br />

Optionally, the circuit breaker can be equipped with<br />

following indicators:<br />

POSITION INDICATOR (Code 14) - mounted at the front of<br />

the closing drive. Mechanically switched by means of<br />

drive’s rod. Indicates position of the main contacts.<br />

“O” – means contacts are open<br />

“I” – means contacts are closed<br />

<br />

<br />

<br />

<br />

<br />

A high power solenoid is used to perform fast closing<br />

operation. This drive is mounted at the front of the<br />

breaker and is encased in a grounded casing [Fig. 16].<br />

Closing drive is supplied independently from other<br />

controls (-X2 :1/:2), directly from external power source.<br />

Voltage level must be defined at order placement. Rated<br />

power, depends on breaker type, but is between 1.8 kW<br />

and 2.6 kW.<br />

CLOSING command is enable by external potential free<br />

contact at (-X2 :4/:5). Signal duration shall be ~300 ms.<br />

The closing drive system always includes a self-interrupt<br />

control circuit (SU PCB). This circuit enables short<br />

activation with a time of ~150 ms. SU switches power to<br />

the solenoid and automatically disconnects it after<br />

~400 ms.<br />

The SU unit also prevents repeated drive closing, due to<br />

an existing and continuous short circuit conditions and<br />

provides an “anti-pumping” safety feature.<br />

<br />

OC TRIP TAR<strong>GE</strong>T (Code 10) – a potential free, NO contact<br />

mounted at the top of the OCT [Fig. 14]. Provides a signal<br />

when OCT trips.<br />

<br />

After closing attempt, the switch-in mechanism is<br />

electrically blocked for approximately 8 sec. Lock time<br />

increases to 14 sec, if internal C-bank (NEKO) is present.<br />

This prevents premature closing following a short circuit.<br />
