General
YCM3 Series mouldedcase circuitbreaker,is new products,with small compact, modular,high break,double breakpoints,zero arcing,green environmental protection.Suitable for AC 50Hz,60Hz,rated operating voltage 690Vand below, rated current 12.5A to 1600A distribution network,used to distribute electrical energy and protection lines and power supply equipment from overload,short circuit and undervoltage failure hazards.It can also be used as a non-frequent conversion of the line under normal conditions and in the infrequent start of the motor
YCM3 circuit breaker equips with intelligent controller as well which not only makes its current adjustable but also grants protection against overload(long delay),short- circuit(short delay),short-circuit(instantaneous)&undervoltage.It'll certainly improve the entire power system's reliability,continuity &security.RS485 interface,MODBUS-RTU protocol.With MODBUS modul equipped,customers can choose options as below.Remote signal:Switching ON/OFF,tripping,alarm & malfunctional singal indication.
Remote control:Switching ON/OFE,reset.Remote test:3-phase cuttent &N-pole current,grounding current.Remote adjustment:accept and execute remote command to debug remote control .Tripping unit memory recording function,last three time'tripping records can be well traced.YCM3 circuit breaker also obtains isolation function(Can be used as an altermative load switch). Standard:IEC 60947-2.
Operating conditions
1.The altitude of the installation site does not exceed 2000m;
2.The YCM3 thermomagmetictype with temperature of the surrounding medium is -5℃~+40°℃,and the average temperature of 24 h is not more than +35℃.The relative humidity of the air at the installation site does not exceed 50%at a maximum temperature of +40℃ at lower temperatures,there may be a higher relativehumidity,the average minimum temperature of the wettest month does not exceed +25°℃ for the average of the month The maximum relative humidity is not more than 90%,and the condensation on the surface of the product due to temperature changes isconsidered.
3.YCM3 intellgent type with temperature of the surrounding medium is - 40°℃~+80°℃.
4.The product is used in non-explosive hazardous media,and the media does not have enough to corrde metals and destroy insulating gases and conductve dust.
5.In places where there is rain protection and no water vapor.
6.The installation category is ClassⅢ
7.The pollution level is level 3.
8.The basic installation of the circuit breaker is vertical (je vertical)or horizontal (e horizontal).
9.The incoming line is either the up line or the down line.
10.Circuit breakers can be divided into fixed andplug-in types.

Note:
Other requirements at the time of ordering are subject to textual instructions.

Release:
The type of stripper is divided into:thermal magnetic stripper and Intelligent stripper
1.Thermal magnetic stripper is divided into types according to protection type Distribution Protection Code:TM;Motor (single-magnetic)protection Code:MA.
2.Intelligen stripperAccording to the function is divided into three kinds: ordinary type,liquid crystal type and with voltage detection type
