NJBK5 Motor Controller
1. General
NJBK5 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 11kW (current up to
22A) to control the direct start and stop of water pumps or
motors, 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: IEC 60947-4-1.

3. Operation conditions
3.1 Altitude: the altitude of the mounting location should not
exceed 2000m;
3.2 Ambient tempeature: -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 Mounting 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°.

4.4 Protection characteristics of the controller
4.4.1 Phase failure protection characteristics of the controller: In case of failure of any phase of the three-phase main circuit passing
through the center hole of the motor comprehensive protector in the controller, the motor comprehensive protector operates for a
period of ≤5s.

5. Features
The controller consists of a CJX2 series AC contactor, a JD-8 series motor comprehensive protector and an NJB1-YW1 liquid level relay
in a protective enclosure and is divided into two types, with liquid level relay and without liquid level relay. Products with liquid level relay
are used to control the start and stop and automatic pumping and drainage of water pumps and provide overload and phase failure
protection. Products without liquid level relay are used to control the start and stop of motors and provide overload and phase failure
protection.
Setting of the motor comprehensive protector in the controller is required before it is connected and put into use.
