OPERATION CHARACTERISTIC
THE OPERATION CHARACTERISTICS OF HK CIRCUIT BEAKERS ARE IN COMPLIANCE WITH CHARACTERISTIC OF STANDARD CEI 23-3 AND CEE 19.

THE DIAGRAM BELOWS SHOWS HOW THE OPERATING RANGE OF HK CIRCUIT BREAKERS IS DEFINITELY WITHIN THE VALUES PRESCRIBED BY THE SPECIFICATIONS.

THE OPERATING CHARACTERISTICS ARE CONSIDERED AT THE ROOM TEMPRETURE OF 20 5 C.

IN CASE OF HIGHER TEPRETURES, THE TEMPRETURES RELAY OF ALL THE CIRCUIT BREAKERS DECREASE THE CURRENT PROGRESSIVELY WITH INCREASE IN TEMPRETURE ACCORDING TO STANDARDS, WITH A 40 C TEMPRETURE, WHICH IS APPROXIMATELY THE TEMPRETURE THAT CAN BE ATTAINED IN FULLY WIRED, A 20 % APPROXIMATE DECREASE IN THE RATE CURRENT VALUE IS ALLOWED.

CONSTRUCTION
CIRCUIT BEAKERS ARE EQUIPPED WITH A TRIP DEVICE ENABLING THE CURCUIT BEAKKERS TO OPEN THE CONTACTS IN CASE OF OVERLOADS OR SHORT-CIRCUIT EVEN WHEN THE LEVER IS IN CLOSE POSITION.

ALL THE POLES OF MULTI POLAR CIRCUIT BREAKERS ARE INTERCONNECTED BY MEAN OF A DEVICE THAT OPENS THEM SIMULTANEOUSLY.

BOTH CONFIGURATION AND LAYOUT OF ALL THE COMPENENTS THAT PROVIDE THE AUTOMATIC OPENING O THE CONTACTS IS SUCH AS TO MAKE THE OPERATION VERY FAST WITHOUT DAMAGING THE OTHER COMPONENTS.

THE CIRCUIT BREAKER FRAME IS MADE OF HIGH HEAT RESISTANCE SELF-EXTINGUISHING INSULATED MATERILA.

BREAKING CAPACITY
AUTOMATIC CIRCUIT BREAKERS ARE SUBDIVIDED INTO TWO SUB-CATEGORIES ACCORDING TO THEIR BREAKING CAPACITY WITH DIFFERENT IN CONSTRUCTION AND USE.

SERIES 9000 WITH 3000 A BREAKING CAPACITY:INCLUDING THE MULTI-POLE CIRCUIT BREAKERS FROM 5 TO 80 A.PARTICULARY SUITABLE FOR CIVIL USE WHERE SHORT-CIRUIT CURRENT RARELY OVERCOMES 3000A

SERIES 9000 WITH 6000A BREAKING CAPACITY:INCLUDING THE MULTI POLE CIRCUIT BREAKERS FROM 5 TO 80A. PARTICULARLY SUITABLE FOR USE IN INSTALLATION WITH THEIR OWN TRANSFORMER ROOM WHERE THE SHORT -CIRCUIT IS EXPECTED TO ATTAIN HIGH VALUES, OWING TO THE PROXIMITY OF THE MV/LIVE TRANSFORMER.HIGHER BREAKING CAPACITIES COULD BE PROVIDED.








FITTING
HK CIRCUIT BREAKERS ARE EQUIPPED WITH A DEVICE TO REALSE CLAMPING ON DIN 46277/3 SECTION AND THUS CAN BE FITTED TO MOST ENCLOSURES, SWITCH BOARDS AND CUBICLES AVAILABLE ON THE MARKET.

ALL EQUIPMENT SHOULD BE FITTED STRICTLY FOLLOWING THE SPECIFICATIONS GIVEN FOR ELETRICAL EQUIPMENT ACCORDING TO THE LIVE RELEVANT STANDARDS

IN PARTICULAR, SPECIAL CARE MUST BE GIVEN IN COMPLYING WITH THE INSULATING DISTANCE AND AVOIDING THE LIVE COMPONENTS TO BE ACCESSIBLE.

AEI HAVE DEVELOPED A FLUSH ENCLOSURE WHICH ENSURE PROPER FITTING OF THE HK CIRCUIT BREAKERS AS WILL AS PERFECT AESTHETICAL COORDINATION.

THIS ENCLOSURE COMES COMPLTET WITH ONE OR THREE PHASE, EARTH AND NEUTRAL BUS BARS.

HK CIRCUIT BREAKERS ARE EQUIPPED WITH WIRING HARNESS EASY AND RAPID WITHOUT REQUITING ANY PRELIMINARY DRESSING.
