Product Description

Parameter

• OUTLINE

This breaker's rated in sulation volage is 800V,is applied to distribution network circuit of AC 50HZ,rated working voltage up to 400V,rated working current up to 800A,which is for electrioenergy distribution,circu protection,protecting power dupply facility form destroying by the foultof overloading,short cicuit and underoltage,meanwhile it is also used for proteotion form unfrequent starting,over loading,short circuit and unervdtage of the eletromotor

This beaker has suehcharaoteraoteristics of company volume,high short circuit interrupting capacty,shortflacharoing and etc which is a idealproduct for users,

This breaker can be installed vertically(upringht),and also horizontally.this breakercomply with standard IEC60947-2、GB14048.2.

• CIRCUIT BREAKERS CODES AND LMPLICATIONS

• MAIN FUNCTIONS AND FFATURES

□Residual current three-phase protection:LM1LE circuit breaker achieves g ground fault protection.The working power of the conventional leakage protection module with residual current circuit breaker is as follows:Two-phase,this series of cirrcuit breakers are three-phase,if any phase is missing,the circuit breaker leakage protection module can work normally;

□Field adjustable:rated residual operating current 1 △ n and residual curre ent operating time(non-delay and delay)are adjustable on site according to the actual situation;

□Low voltage protection:When the phase voltage is reduced by 50V,the leakage protection module can still work normally;

□With leakage alarm output function:When the residual current of the equipment or line reaches or exceeds the set value,the circuit breaker with the leakage alarm unit module outputs a passive connection Point signal,drive the correspondinng alarm device;

□Installation is interchangeable:the external dimensions and installation dnimensions are the same as those of the LM1LE series circuit breakers (LM1LE-630 and LM1LE-800 are the sme),and the installation is better Interchangeability.

□Release mode and intemal accessory code The frst digit 2indicates the electromagnetic (instantaneous)release,3 indicates the themodynamic-electromagnetic (duplex)release;the last two digits indicate the intemal accessory code,f there are no accessories,use 00.

□In LM1LE-400,630,the auxiiary contacts of 228,328,248,and 348 specifications are a pair of contacts (that is,one normally open,one nomally closed),and the auxiiary of 268,368 specifications are three pairs of contacts(that is,three normally open,Three normally closed).

□LM1LE-100,225220,320,240,340 auxiary cnlects can provicetwo pairs of ccntacls (etwo nomally open two nomaly cbsed),butmust be specified when crceing □If the LM1LE series has a leakage alarn unit module,the attachment only provides ▲ specifications;there are two ways for the leakage alarm unit module,which the user indicates when ordering:

Method 1:When aleakage occurs,the leakage alarm module sends a signal and the circuit breaker tips at the same time;

Method 2:When a eakage occurs,the leakage alarm module sends a signal,but the circuit breaker does not tip.In order to meet the needs of special occasions, users should consider this carefuly when usingthis function to product electrical appliances.

□See the product identfication or instruction manualfor thewiring diagram of the leakage alarm module.P1-P2,P3-P4 are normally open and nomally closed contacts,the contact capacity is AC230V5A,and the inout power of P5-P6is AC50Hz.230 or 400V(according to the user Need to choose)
