HSM6 Series Moulded Case circuit breaker

1, Application
HSM6 Series Moulded Case circuit breaker (MCCB in brief hereinafter)adopted of advanced current limiting technology and has simple tripping mechanism design. A new short circuit tripping release (full series is *0in protection range) designed were compact, high breaker capacity, zero arc with Isolation integrate all of function. Compare to others similar products we had high performance, structure compact and same outline size and installation that could be replacement them.

MCCB for AC *0Hz with rated insulation voltage **0V and rated working voltage below **0V. its for distribute power in the rated current *0A~**0A circuit. At regular working condition as for infrequency witch ON and OFF and breaking the circuit meanwhile protection electrical equipments against overload ,short circuit and under voltage when it operation.

MCCB rated current below **0A could be as squirrel-cage motor for infrequency starting .With a protect function when motor happed overload ,short circuit and under-voltage on the operating.

MCCB had functional overload alarming but not tripping when the circuit is overload. It could be get power continue if MCCB had this function will be not tripping only output overload signal that's conform to and meet requirements of standard GB***5 Article 4.3.5 "Suddenly broken the power will be make big loss then overload for electric circuit, And overload protection by signal not for broken power in the electric circuit."

The MCCB have special products for photovoltaic system according to standard Q/GDW***2,Q/GDW***3 suitable for **0V/**0V distributed photovoltaic grid connected to the National Power Grid Company.

The MCCB has disconnecting function and its corresponding symbol is shown as .

The MCCB conform to standard IEC******2,IEC******4

The MCCB many wiring method : wiring in front of the board, wiring on rear of the board ,wiring by plug in ,wiring of draw-out and wiring of fixed
 
Type designation and classification
2.1 type designation

Note:
1.No code for handle directly operation, D for electric handle, Z for external transfer operation handle.
2.Overload alarm but no tripping MCCB only have electromagnetic tripping release.(There is no this function for HSM***3 and others 4P MCCB with the N pole is Curve D,C )
3.No code for MCCB distribution , motor protection is code 2
4.Rated short circuit breaking capacity : type S(Standard Model),type M (Middle breaking model),type H( High breaking model), type L(Top breaking model).

2.2,Classification
1.As function the MCCB have distribution type and motor protector type
2.The MCCB many wiring method : wiring in front of the board, wiring on rear of board ,wiring front board by plug in ,wiring rear board by plug in .
3.According to operation have handle operated , external transfer handle operation, electrical operation
4.The tripping release has instantaneous tripping release (Electromagnetic **0); Thermal Thermodynamic tripping release (multiples: **0)
5.The MCCB has 3P and 4P
The MCCB neutral pole (N Pole) of the 4P products has four model:
Type A: N-pole without over-current tripping release , it has been connected all along, and does not act with other three poles to switching ON or OFF
Type B: N-pole without over current tripping release , it could act with other three poles switching ON or OFF
Type C: N-pole have over-current tripping release, it could act with other three poles switching ON or OFF.
Type D: N-pole have over-current tripping release , it has been connected all along, and does not act with other three poles to switching ON or OFF
6.The Auxiliary installation could be choice Device with auxiliary and Device don't with it.
Form 1 Tripping release with auxiliary code
 
 working conditions and installing conditions
The MCCB applicable environment as below:

1.Installation Elevation≤***0m

2.Ambient temperature:*5ºC ~**0ºC

3.There must be not any explosive medium, and there must be not any gas which would corrode metal or any conducting dust which would destroy the insulation.
