Functions and applications
JECPS adopted the module structure，integrated with the main functions of conventionaI breaker(fuse),contactor,
overlcadIng(over—current,or phase fai|u re)relay。starter，isolator,motor comprehensive protectlnq device and
etc low oltage electric appliances it can be aut0一contr0|Ied remotely or operatedocallybypersonnel,provide spanel indications,
signal warning function for motor， over voltage,absent—voltage protection，phase—failure，phase absence protection, under-current and Jower power performances,selective time-current tripping characteristics(fou r step protections overloading inverse time limit，fixed time limit,short circuitinstantaneoustrippin9，extrashortcircuitInstantaneoustripping),
it can choose function modules or accessO ries as required tO rea|ize vatiOUS specified controI and protection for motor and power distrlbution

Product model and meanings
The model indication of basic type shall include：model of main body,rated current oftripper,breaking capacity class,
intelligenttripper，productfunctions,cont rol power source
| Main body It has short circuit protection(similar with MCCCB and fuse)，auto control (similar remotely controlling contactor)。local operation and indications，mainly consists of body，main panel，soleplate．electromagnetic driving mechanism． ope rating mechanism．contact g roup of main ci rcuits(contact system and shorf oi rcuit t ripper)and eto |  |
| Electromagnetic driving mechanism The electromagnetic driving mechanism composed of control coil.iron core, contacts for control,and base(similar with electromagnetic control system of contactor,with under-voltageprotection),itcan receivethecommand ofopening and closin9．namely make or break main circuit via main contacts Symbols of wiring terminals in coil are Al.A2 |  |
| Operating mechanism It can receive the signal e| instantaneous short circuit in each pole and fault signal from electror~ie overload tripper, and break the main circuit via control co,tact to cut off control coil circuit by use of operating mechanism, After eliminating the fault, operate knob to reset, The working states of JECPS operating mechanism are shown in the panel.
