Product Details

1. General

YCQJ7 series motor controller (hereinafter referred to as controller) is mainly used in circuits with a frequency of AC 50Hz (or 60Hz), a rated operational voltage of up to 380V and a rated control power of up to 18.5kW (current up to 38A) to control the direct start and stop of water pumps ormotors, provide motors with overload and phase failure protection, and realize automatic liquid level control for civil water towers and reservoirs.This product is not applicable to the liquid level control of low-conductivity liquids, such as oil, puriﬁed water,inﬂammable and explosive chemical liquids and high-density sewage.

Standards:lEC 60947-4-1.

3. Operating conditions

3.1 Altitude: the altitude of the mounting location should not exceed 2000m;

3.2 Ambient temperature: -5℃~+40℃, and the average temperature in 24h should not exceed +35℃;

3.3 Atmospheric conditions: The relative air humidity at the mounting location should not exceed 50% at the maximum temperature of +40℃ . The relative humidity may be higher at lower temperatures.Special measures should be taken if condensation occurs on the product occasionally due to temperature variation;

3.4 Pollution degree: 3;

3.5 Installation category: Ⅲ;

3.6 In places where there is no significant vibration or impact;

3.7 In non-explosive media that do not contain a sufficient amount of gas or dust to cause metal corrosion or insulation failure; 3.8 In places where rain and snow protection is provided;

3.9 The inclination from the vertical plane should not exceed 5° .

5. Features

The controller consists of a CJX2s series Ac contactor, a JD-8 series motor comprehensive protector and an YCL8 liquid levelrelay in a protective enclosure and is divided into two types, with liquid level relay and without iquid level relay. Products with iquid levelrelay are used to control the start and stop and automatic pumping and drainage of water pumps and provide and stop and automatic pumping and drainage of water pumps and provide overload and phase failureprotection. Products without liquid level relay are used to control the start and stop of motors and provide overload and phase failureprotection.

Setting of the motor comprehensive protector in the controller is required before it is connected and put into use.
