a.With control and protection from common characteristic

SCPS series control and protective switching devices with control and protection functions,

equivalent circuit breaker ( fuse ) + auxiliary electrical overload relay contactor.

Very good solution to the separation element cannot or difficult to solve element between the

protection and control characteristics matching problem, so that the protection and control

characteristics with more perfect and reasonable with inverse time limit, and the instantaneous

protection characteristic of three segments .

b.With the operation reliability and continuous system operation performance

SCPS in breaking short circuit current without maintenance can be put into use, that is breaking

short circuit faults of continuous running performance: SCPS in the breaking short-circuit current after the test, is not less than 1500 AC-44 electric service life,

which is composed of circuit breakers and other separation components the system is difficult to

achieve, SCPS of this feature of the system is greatly improved the reliability of operation and

system integration of continuous operation, the Ics 80kA index is similar products in the leading

international, domestic highest index.

c. Saving energy and material:

SCPS has the advantages of small volume, small installation area, without a separate component

contacts, reduce line heating, energy saving, material saving etc..

d. With high breaking capacity, arcing distance short of the characteristics

SCPS in 380V rated short-circuit breaking capacity ( Ics Oco-co ) reached high

breaking type 80kA, type 50kA, type of economic standard for 35kA, 50kA expected in

short circuit current breaking time is 2 ~ 3MS, limiting factor reached 0.2 the following,

reaching the leading level of molded case circuit breakers.

e. Installation of flexible

Horizontal, vertical, horizontal installation the installation does not affect the use of performance.

Can be widely used in compact sets of devices, including a fixed type or a drawer type MCC

cabinets, especially SCPS 12, 16, 18, 32, 45 in 1 / 4 and 1 / 2 Drawer in the application, with

separate components incomparable superiority.
