General
YCM3 Series moulded case circuit breaker, is new products, with small compact,modular, high break, double breakpoints, zero arcing, green environmental protection. Suitable for AC 50Hz, 60Hz, rated operating voltage 690V and 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/OFF,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 alternative load switch).
Standard: IEC 60947-2.
Operating conditions
1.The altitude of the installation site does not exceed 2000m;
2.The YCM3 thermomagmetic type with temperatureof the surrounding medium is-5℃~+40℃,and the average temperature of 24 h is not more than +35℃.Threlative humidity of the air at the installation site does not exceed 50%atmaximum temperature of +40℃;at lower temperatures,there may be a higherelative humidity;the average minimum temperatureof the wettest month does ncexceed +25℃ for the average of the month The maximum relative humidity is ncmore than 90%,and the condensation on the surface of the product due ttemperature changes is considered.
3.YCM3 intellgent type with temperature of the surrounding medium is40℃~+80℃.
4.The product is used in non-explosive hazardous media,and the media does nothave enough to corrde metals and destroyinsulating gases and conductve dust.
5.In places where there is rain protection and no water vapor.
6.The installation category is Class Ⅲ.
7.The pollution level is level 3.
8.The basic installation of the circuit breaker isvertical (ie vertical)or horizontal
(iehorizontal).
9.The incoming line is either the up line orthe down line.
10.Circuit breakers can be divided into fixed and plug-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 lntelligent stripper 1. Thermal magnetic stripper is divided into types according to protection type
Distribution Protection Code: TM; Motor (single-magnetic) protection Code: MA. 2. Intelligent stripper According to the function is divided into three kinds:
ordinary type, liquid crystal type and with voltage detection type.
